Bubbles – Many chemical reactions you see in the science lab make a chemical which is a gas, so you see bubbles. A colour change – If the new chemicals are a different colour from the original ...

Some chemical reactions change temperature, change color, produce a gas, or make a solid from two liquids. Try this reaction and see what it does! Pour 1 tablespoon of hydrogen peroxide into a cup.

Hydrogen peroxide decomposes on its own into water and oxygen gas. This process is sped up by a catalyst. In this reaction, the catalyst is potassium permanganate, and the bubbles are full of oxygen ...

To promote the science of gas kinetics from the fundamental dynamics of gas phase reactions to the application of kinetics to the understanding of complex processes. To support the interests of all ...

Reactions in which a gas is produced can be used to monitor the rate. For example, hydrogen gas is one of the products released when dilute hydrochloric acid reacts with zinc metal. By collecting ...
