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.
