Name the reactants and the products in each, and write the word equation.
- Magnesium burns in oxygen to give magnesium oxide.
- Zinc reacts with hydrochloric acid to give zinc chloride and hydrogen.
Need a reminder? The key ideaShow
A chemical equation shows the reactants on the left and the products on the right. State symbols: solid, liquid, gas, dissolved in water. Gases such as oxygen, hydrogen and chlorine are written as , , . A number after a bracket multiplies everything inside it.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. (a) Reactants: magnesium and oxygen. Product: magnesium oxide. magnesium + oxygen magnesium oxide.
Step 2. (b) Reactants: zinc and hydrochloric acid. Products: zinc chloride and hydrogen. zinc + hydrochloric acid zinc chloride + hydrogen.
Answer: as above.
