The rate of a chemical reaction is a measure of how fast the reactants are being used up and how fast the products are being made. Reactions in which a gas is produced can be used to monitor the rate.

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 ...

If they collide with enough energy, bonds can break and new bonds can form in a chemical reaction. The reactants just sit there until energy is added with the flame. The added energy is enough to make ...

Chemical reactions can take in energy or release energy, often in the form of heat. This causes a change in temperature. There are two different types of energy change that can take place.

Add one or two drops of 1% bromine in dichloromethane to one sample of each hydrocarbon. Compare the rate of the reactions and the conditions. Add one or two drops of 5% KMnO4 to the second sample of ...
