An iron nail is placed in a solution of blue copper(II) sulfate. Over time, a brown solid appears and the solution becomes colourless. This is because copper and a solution of iron(II) sulfate forms.

To balance an unbalanced equation, you need to add numbers to the left of one or more formulae. Here is one way to work out how to do this for the reaction between nitrogen and hydrogen.

Some chemical reactions change temperature, change color, produce a gas, or make a solid from two liquids. Try this reaction and see what it does! Pour 1 tablespoon of hydrogen peroxide into a cup.
