Hi, I need some help on putting word equations into chemical equations and balancing.

1. Sodium phosphate + calcium chloride ----> calcium phosphate + sodium chloride

2. Calcium hydroxide + phosphoric acid ----> calcium phosphate + water

3. copper + sulfuric acid ---> copper (II) sulfate + water + sulfur dioxide

Any help is appreciated, thanks!

Have a go and tell us where you get to, we will then look at your answers and see if you have done anything wrong, okay? :)

Remember to use valences to make sure your compound formulae are okay, then once you have all the formulae okay, have a go at balancing, remembering that there must be equal amounts of each element on each side of the arrow.

The first one is 2 Na3(PO4) + 3 CaCl2 --> Ca3(PO4)2 + 6 NaCl

Zinc + lead(II) yield zinc nitrate + lead

Zinc + lead (II) nitrate yield zinc nitrate + lead
