A calorimeter, or a thermometer. Depending on how specific you want to be, and what measurement your looking for.
These are decomposition reactions.
Oxygen as most reactions have it although it could also be hydrogen
Some common laboratory apparatus include beakers, test tubes, graduated cylinders, pipettes, and Bunsen burners. These tools are used for various purposes such as measuring, mixing, heating, and observing chemical reactions.
All chemical reactions have a common structure. It must have reactants, that are the substances that you have at the beginning, and the product that are the new substances you get at the end.
The most common way to speed up chemical reactions in non-living systems is to add heat. Heat causes the molecules to move faster, creating more collisions. In some reactions, extra oxygen is used to speed them up.

Metals rusting, wood or fuel burning, yeast fermenting sugar, and cellular respiration are common chemical reactions.

Explain why energy is necessary to chemical reactions, and describe some common sources of energy.
Energy is necessary for chemical reactions because it allows molecules to overcome activation energy barriers and initiate reactions. Common sources of energy for chemical reactions include heat, light, electricity, and catalysts. These sources provide the necessary energy to break existing bonds and form new ones during a chemical reaction.

Some signs (or evidence) of chemical change are: a gas is produced, the temperature changes, a substance disappears, a solid is formed a colour change occurs, a new odour is produced.
