Working With Compounds - l

 We mixed Manganese dioxide(MnO2) and Hydrogen peroxideH2O2) together and a chemical reaction occurred. A chemical reaction is a process in which substances undergo chemical change. Some indications of a chemical reaction include: smoking, bubbling or foaming, change in temperature, a color change, or an odor. This chemical reaction bubbled. Bubbles indicate the presence of a gas. We tested the gas with a glowing wood splint and the splint burst into flames indicating that the gas was oxygen (O).
