Esters

lab 9.4  William philip
In this lab we synthesized esters.
we started off with a small test tube, we added 5ml of ethanol and then we added 6ml of acetic acid.
After we mixed the ethanol and the acetic acid we added 10 drops of sulfuric acid, the sulfuric acid acted as a catalyst to the reaction.
Then we set up a beaker full of water on a hot plate and waited for it to boil, after it had started to boil we clamped the test tube to a ring stand and lowered the test tube into the hot water, we put a small beaker over the test tube to keep it from overflowing into the water.
After about 10 minutes in the hot water we took out the test tube and put it in another beaker full of cold water to cool it off.
After the test tube had cooled off we diluted the ester with 30ml of water and then smelled it.
The ester smelled just like acetone in nail polish remover.

apparatus used: 5 ml ethanol
                                 6 ml glacial acetic acid
                                 10 drops of concentrated sulfuric acid

ion flame color testing

These are the results i obtained from the flame tests.
The CoCl burned orange.
The LiCl burned  cherry red.
The CaCl burned an orangish red.
The CuCl burned green.
The NaCl burned bright orange.
The KCl burned a light purple.
The SrCl burned red.
The FeCl burned orange.
The BaCl burned leaf green.

the unknown chemical was a blue solution, and it burned green and purple, so that would mean that there was potassium and copper in it.
Also copper sulfate is a blue color.

mid-term evaluation

                                                  mid-term evaluation
What I enjoy doing the most is the labs, like the vitamin C lab.
I like learning things about science and technology that I wouldent have normaly known.                          The online blog posts make it easy to get in projects from home, and it is faster then writeing them by pen.
It is also nice to have time in the computer lab or on my blog app to work on other projects that are needing to be done.

I am finished my photo essay.   (:

features of personal technologies

The personal technology that i have chosen is my cell phone.
The feature i will talk about is the LCD screen (liquid crystal display).
the screen  is a 4.3" super AMOLED plus display screen, and the screen resolution is 480x800
there are many uses for LCD screens, some of them include cameras, cellphones, watches, computers and an infinite number of other things have them.
The technology just keeps getting better for LCD screens, every year the LCD screens have better resolution and are thinner. the LCD screens today are much thinner and the price for them keeps going down.

Volunteering

For my 5 hours of volunteer work I did landscaping at the school.
What I did is help dig trenches in the back field of the school for the irrigation system so that the field gets watered.
It benefited the school community because it helped water the grass so that we can play sports in the back field. It would be harder to play football or soccer on dead grass because there would be not as much grip. And grass also looks better green.

baking soda/powder

This lab is about the reaction of baking soda and vivigar vs the reaction of baking powder and water.

My prediction was that the baking soda would  react more then the baking powder

when I mixed the baking sona and the vinigar they reacted fast and created lots of what i think is carbon dioxide gas.
when I mixed the baking powder with water it reacted much slower, but over a longer time.
 So the baking soda does react more then the baking powder.

prediction
1)BaOH+H2SO4-->BaSO4+H2O there were no noticeable changes.
2)Cl+NaI-->NaCl+I, the solution became an orange color.
3)Zn+CuSO4-->ZnSO4+Cu, the blue liquid became clear.
4)CaCl+NaCO3-->CaCO3+NaCl, there was a white precipitate.
5)CoCl2+NaOh -->NaCl2+CoOH, there was a blue precipitate.
6)Ca+H2O-->H+CaOH. there was lots of gas bubbles and the solution turned white.
7)NaCH3COOH+HCl-->NaCl+CH3COOH
8)Mg+2HCL--->MgCl+H2, this reaction produced lots of gas.

My Personal technology

All the date that I obtained from personal technology chart pointed to one thing.

The personal technology that I use the most would be hands down, my smart phone.                                                          It goes above and beyond all my basic needs.  It can do almost everything that a computer can do, and even things that a computer can’t do, for example, I can download movies or music and instantly share them wirelessly on my TV using all share.  I also find my Samsung galaxy S2 really good for photography because I can take my card out of my camera and put it into my phone and from there I can load it onto Facebook  instagram, or pintrest wherever I am.

If I didn't have my phone, it wouldn't make that big of an impact on me because I went most of my life not having it and didn't realize that I was missing anything. It is just a luxury not so much an essential. If I did loose it, I would definitely use the computer a lot more to check my email, Facebook, etc.

I mentioned some of the positives of having a smart phone, but I also want to bring up some of the negatives.  The first one that comes to mind is that people become consumed with their phones.  No matter where they go, or what they do, they’re with a few hundred of their friends.  I personally know people who are so consumed with Facebook that they have to check it every few minutes to see if anyone commented on their latest status update.  If they aren't doing that, they are messaging their friends about everything that happens and they can never let go of that connection.   It actually stops them from interacting with their environment.  

Is that healthy?  Isn't it important to have private time to think your own thoughts?

Society does try to push people to buy these phones and tells everyone that they can’t live without it.

They tell you that the current phone you have is the old version and you need to get the new one or else you won’t be able to survive. But the fact of the matter is that the current phone that you have is probably still just as good as when you first bought it, though it may have a few more scratches on it, but it still does the same thing in the inside and has not gotten any slower because the new one that just came out is faster.  My conclusion is that if a new version of my phone came out, I wouldn't get it because it really has just a few minor software changes made and looks a bit different.  Of course if something tragic happened to mine, I would definitely get the upgrade.

17) B) steam Condenses
18) B) reduce the concentration of a reactant
19) B) speeds up the reaction
20) Pickled cucumbers would last longer because they are stored in salt or vinigar which is an inhibitor.
21) The beaker of water would have became warm from absorbing heat from the sun, no chemicle reaction has taken place.

24) If I was in a hurry I would choose ground meat rather then meat chunks, because the ground meat has more surface area then the meat chunks, so it would heat up faster then the meat chunks.

26) The steel wool would weigh more after it has reacted with oxygen  because the molar mass of iron is 55.85, and the molar mass of oxygen is 16.00 if you add them together you would get the molar mass of iron oxide which would weigh more then just iron.

Mashups

                                                                              Mash-ups
The first mashup is a mix between Star Wars and the song "call me maybe".
It mixes up diffident lines from Star Wars to sound like the song call me maybe.
I don't think this would be copyright infringement because the people who made this video are not making any money off it, and they are not taking credit away from the artist who wrote this song or the person who made the movie.

The second one is called "Dr monkey the dentist". It is a mashup of random animals with voices put in the background to make it look like the animals are talking. I don't think it is copyright infringement because they give credit to the BBC.




Here are the two mash-ups that I have selected.

Vitamin C test

What we did is test oranges for vitamin C (ascorbic acid)
How it works, vitamin C eats starch, and sodium iodide is an indicator for starch.
So we made a solution of starch water and an iodide solution. We put a small amount of starch water in a test tube, and a small amount of iodide. When added the iodide will turn a very dark blue
Then we put some orange juice in the test tube, if the orange has vitamin C in it, the mixture of iodide and starch will go from dark blue to a clear pink.
Apparatus
Solution if sodium iodide.
Solution if potato starch.
Multiple Test tubes.
We tested onions, tomatos, apples, oranges, a random juce, milk, and bread.

The tomato had vitamin C

The apple did not have vitamin C

The orange had vitamin C

The bread did not have any vitamin C

The milk did not have any vitamin C

The onion did have vitamin C

The random juce did not have any vitamin C

There were more that had no vitamin C then did

John

A man named nicodemus came to Jesus in the night and said, "rabbi, we know that you are a teacher who has come from God. No one else could perform these signs you are doing.
Jesus told him that no one can see the kingdom without being born again.
But nicodemus said, " how can we be born again when we are old"
Jesus reply "very truly i tell you, no one can enter the kingdom without being born of the water and the spirit"
You should not be surprised at my saying, you must be born again.
The wind blows wherever it wants to. You hear its sound, but can't tell where it comes from or where its going. So it is with everyone born in the spirit.
How can this be? asks Nicodemus

Conservation of mass

Today we looked at the conservation of mass.
We put a bit if steel wool in a test tube and filled it about 1/8 of the way full, and I also added about 10ml of a solution of impure potassium chlorate.
Next I filled a balloon with air and placed it over the test tube.

Why? the reason for this is to find out if the steel wool will loose or gain mass after it oxydises.

After a few weeks sitting in the test tube I looked at it and saw that it was rusty.
 before I started this experiment it weighed 23 grams, now it weighed 24 grams. so this proves that this theory is correct in that iron will gain mass when combined with oxygen.

the molar mass if iron is 58.84g\mol
the molar mass of oxygen is 16.00g\mol

So the molar mass of iron oxide is 159.68

Ph scale

William Philip


In science class, we tested the pH of vinegar, bleach, lemon juice, baking soda, soap, oven cleaner, and antacid tablets.  I tested all these substances by dipping a pH strip into each individual chemical to get the results that would allow me to know if they were acidic or basic.

My hypotheses was that the vinegar and lemon juice were both acidic.
 the bleach, antacid, baking soda oven cleaner and soap were all basic

My hypothesis was correct.
The vinegar, and the lemon juice were both acidic. the vinegar was PH 3, the lemon juice was PH 2.
The bleach, antacid, baking soda, oven cleaner, and soap were all basic.
the bleach was pH 12, the antacid was pH 9, the baking soda was PH 9, the oven cleaner was pH 13, the soap was pH 12.

Catalace

In science and tech we experimented with Catalace.
We filled several test tubes with hydrogen peroxide, and put small pieces of liver and potato in it.
My Hypothesis: when we put the liver or the potato in the test tube of hydrogen peroxide it will decompose, it would be an exothermic decomposition reaction.
The amount of foam produced depends on the concentration of hydrogen peroxide and the amount of Catalace in the liver.

When we put the liver in the test tube it instantly started to foam and produce heat.
When we put potato in the test tube it didn't foam very much, and didn't produce a very noticeable amount of heat.
Next thing we did is we put the test tubes in boiling water  to heat up the hydrogen peroxide, when i put the liver in the test tube it made a lot more foam then when not heated. when I put the potato in the test tube of hot hydrogen peroxide it didn't foam as much as it did in the cold hydrogen peroxide did.

What I also did is test blood from dog meat for Catalace, when i mixed the blood with the hydrogen peroxide there was an explosion of foam much bigger then there reaction to the liver.
 So I would say that blood has a much lager concentration of Catalace in it then liver or potatoes do.

water quality testing

                                               Water quality testing lab report 


In science and technology class, we did water quality testing.  Water quality testing consists of several water tests such as testing the pH, dissolved oxygen, alkalinity, Po4, no3 and so on.

What we did for the dissolved oxygen test is this: we had a kit that came with a box of air tight ampules, each containing a small amount of yellow liquid in them.  It came with a plastic beaker as well.  We filled the beaker to the 25 ml mark and then proceeded to put the glass ampule in the beaker and broke the tip off of it. The ampule filled with water  immediately, and the yellow liquid turned blue when it came in contact with the oxygen in the water.
After waiting for two minutes, we compared the filled ampule with other tubes that were filled with a blue solution, and we identified the one that looked the most similar to it in shade.  The number under the tube tells us how many ppm's of oxygen it had.

 The pH, no3, Po4, and total alkalinity tests were all very simple as well.   All we did is use test strips that indicated what the number was, then dipped them in the sample of water, which in this case was my fish tank water.
Here are the test results we got:


total alkalinity: 80
No3: 50 ppm
Po4: 15 ppm
pH:8
dissolved oxygen: 7ppm

paper chromatography

in chemistry class we did paper chromatography
what we did is we made a cone out of filter paper and put it in an appropriately sized beaker.
Next we got another piece of filter paper and put different colored dots on it with a felt marker.
then we put the paper on the cone and then filled the beaker with water.

What i observed
the water started to slowly soak up the paper cone and then the paper on top of the cone
