In this video explains atoms or molecules combine to form a new compound in a synthesis reaction. Examples include the addition of oxygen to magnesium metal to create magnesium oxide and the addition of carbon dioxide to water to crete carbonic acid. A combine breaks down into new atoms or molecules in a decomposition reaction. Examples include the break down of sodium azide in a airbag or the break down of hydrogen peroxide in your cells. Decomposition reactions will often release heat as bonds are broken and new bonds are formed.
