I need help in chemistry

The question asks: "Write reactions to show dissociation into ions of the following substances when they dissolve in water: a) sodium carbonate b) magnesium chloride c) ammonium hydroxide"

So do I just write the chemical equation for sodium carbonate and water? Magnesium and water? and ammonium hydroxide and water?

No! You only need to show into which ions the original compound breaks up into!
For example, take Na2CO3 this breaks up as

Na2CO3 ------> 2Na^+ + CO3^2-

Include the state symbols:

Na2CO3(s) ------> 2Na^+(aq) + CO3^2-(aq)
