Word equations in Chemistry????

I have a bunch of word equations(chemistry ones) that I have little to no idea on how to solve them. If you can help solve at least one of them, that would be of great help. Thanks in advance. Here they are:

1. sodium phosphate + calcium chloride yield(that's the arrow pointing from the reactant to the product)calcium phosphate + sodium chloride

2. potassium chlorate yields potassium chloride + oxygen gas

3. calcium hydroxide + phosphoric acid yield calcium phosphate + water

4. copper + sulfuric acid yield copper(II) sulfate + water + sulfur dioxide

5. hydrogen + nitrogen monoxide yield water+ nitrogen

In case some of you don't know what I'm talking about, I'm supposed to change the words into the actual symbols and numbers. For example, this is what it's supposed to lok like: N2 + H2 ----> NH3. All the numbers are supposed to be subscript. Please put the # of the one yo olved next to it If you can figure these out, that's be great. If not, well, then, you get two free points=)
