In our science class, we did a few experiments involving chemical reactions, equations and balancing them. The first experiment was with calcium metal and water. We were testing hydrogen gas. We used two test tubes and we had a flame. When the flame came in contact with the gas, it caused the flame to go out and made a loud popping noise. When the hydrogen gas and oxygen were mixed together it created a reaction, which concludes that it worked and we successfully tested hydrogen gas. Next, we were testing oxygen gas with hydrogen peroxide. The glowing splint caught on fire and also created a small popping noise. There was that noise due to how fast the heat and oxygen molecules reacted with each other. This experiment was successful in creating oxygen gas. The last experiment was testing carbon dioxide gas using carbonate and hydrochloric acid. When the flame went out when it came in contact with the gas. This was also successful because carbon dioxide takes away oxygen. The flame went out because it needs oxygen to keep burning but it came in contact with the carbon dioxide, which resulted in no flame.
