Conservation of Mass Lab Investigation

Today for our latest experiment we mixed soda and pop rocks. At first I believed that i would create a big reaction so i was kind of dissapointed when I saw the real outcome. It barely released any gas. The vinegar and the baking soda had a much bigger outcome than the soda and the pop rocks. It fizzed up almost all the way to the top. It created a lot of gas and it almost filled halfway of the balloon. The gas that both of the combinations released was CO2 and the reason that the soda and the pop rocks didn't create the most gas is because the pop rocks and the soda already have the Co2 gas so when the two combinations met, they just released all of it . The soda and the pop rocks was not a chemical reaction because it was just releasing the gas that it already had in there. In the pop rocks package it says that it is processed with carbon dioxide. The soda too, is processed with carbon dioxide.

Chemthink: Chemical Reaction

1.) reactants.
2.) products.
3.) chemical change has taken place.
4.)there is a rearrangement of chemical bonds.
5.) breaking and forming
6.) atoms
7.) missing atoms or any new ones.
8.) rearrange the bonds
9.) 2 atoms of H and 2 atoms of O as reactants. 1 molecule of H2O 2,1 atom of O leftover. =H2O.
10.) 2 H2 + 1 O2 = 2 H2O
11.) Law of Conservation of Mass
12.) mass ,atoms
13.) 2 Cu + 1 O2 . 2 CuO
14.) 1 Cu atoms ,1 Cu atoms , 2 O atoms /,1 O atoms
15.) 2 ,oxygen
16.) oxygen, Cu, Cu
17.) 2 Cu , 1 O2 ,2 CuO ,2 Cu atoms = 2 Cu atoms , 2 O atoms = 2 O atoms
18.) 1 CH4 , 2 O2 , 2 H2O 1 ,CO2
19.) 1 N2 , 3 H2 , 2 NH3
20. )2 KCIO3 , 2 KCI , 3 O2
21.) 4 Al , 3 O2 , 2 Al2O3
Summary:
1.) Chemical reactions always involve breaking bonds.
2.) The Law of Conservation of Mass says that the same atoms must be present before and after the reaction.
3.)To balance a chemical equation, you change the coefficients in front of each substance until there are the same number of each type of atom in both reactants and products.

Sodium Silicate Polymer Lab

I our latest lab we mixed together sodium silicate solution and ethyl alcohol and it formed a polymer. The polymer was solid and was very bouncy when molded into a ball. If i had to describe it , i believe that it kind of looked like a bouncy ball and if you mashed it over and over. If we used more alcohol i believe that it would have been harder and more difficult to mold into a ball.
We bounced it 7 times from 30 centimeters and it got about 24.2 centimeters up. When we refrigerated the ball for about 15 minutes and it bounced about 18 centimeters. As soon as we started to stir it it immediately started to get in the form of a solid.The things that were similar with the one that we did on tuesday is that they were both polymers. In the other lab we did it was a lot more liquidy and squishy. in this one it was a lot more compresses together. If we put it in a ball it was very fragile and it could be very crumbly. It could get completely crumbled up if we bounced it too hard or if we squeezed it too hard with our fingers. it felt kind of waxy while the other one that we did on tuesday was more moisturized. it kinda looked cloudy and the other one was completely white. If you let it sit though for a while it will flatten out
