1. Water breaks down into hydrogen and oxygen: This is a Decomposition reaction. In a decomposition reaction, a single compound breaks down into two or more simpler substances.

2. Leaves make starch using chlorophyll and carbon dioxide: This is a Synthesis reaction. In a synthesis reaction, two or more simple substances combine to form a more complex substance.

3. Food burns in oxygen gas and releases a lot of energy: This is a Combustion reaction. In a combustion reaction, a substance reacts with oxygen to produce heat and light energy.

4. Adding vinegar (acid) to baking soda (alkali) gives a product that is neither acidic nor alkaline: This is a Neutralization reaction. In a neutralization reaction, an acid and a base react to form a salt and water.
