This activity can be used as additional revision support.
This area has 15 chemical equations that need completing. Starting the activity leads you directly to the first equation where you can choose one of three options to fill the gap in the equation.
Look carefully at the equation and determine what may be missing before choosing your option. If you are right you will get a 'tick' and the equation will be completed.
At any point you can go to the help area where you can read about why and how you can balance chemical equations.
This exercise presents you with a series of chemical equations which need completing.
