Reactants and Products.
Work on your own. Circle the product and answer this question:
How do you know a chemical reaction has taken place?
cake
sugar
butter
flour
I know a chemical reaction has taken place because………….………………..
……………………………………………………………………………………………………….
Underline the products in the sentences below. Remember that
a product is what you have made after the experiment has
finished.
1. Haseeb took methane and burnt it in oxygen. This produced carbon
dioxide and water.
2. Iron sulphate is formed when iron is added to sulphuric acid.
Hydrogen gas is also produced.
3. Pupils found that sodium chloride and water were formed when
sodium hydroxide was added to hydrochloric acid.
4. If you add nitric acid to sodium carbonate they will react together and
produce sodium nitrate, carbon dioxide and water.
Now compare your answers with your partner. He or she should
have underlined the reactants.

that a reactant is what you use at the beginning of an
experiment.
