Ok so I have to balance word equations in chemistry and I'm not very good at it. Can someone please help me?

iron(iii) oxide + hydrogen ---> water + iron

sodium + water ---> sodium hydroxide + hydrogen

potassium iodide + chlorine ---> potassium chloride iodine

chromium + tin(iv) chloride ---> chromium(iii) chloride + tin

magnesium + copper(ii) sulphate ---> magnesium sulphate + copper

zinc sulphate + strontium chloride ---> zinc chloride + strontium sulphate

ammonium chloride + lead(iii) nitrate ---> ammonium nitrate + lead(iii) chloride

iron(iii) nitrate + magnesium sulphide ---> iron(iii) sulphide + magnesium nitrate

aluminium chloride + sodium carbonate ---> aluminium carbonate + sodium choride

sodium phosphate + calcium hydroxide ---> sodium hydroxide + calcium phosphate

#1. You should look up the molecular formulas of each of the compounds. For example, Water is H2O. Write each equation using the molecular formulas.

#2. Balance the metal atoms

#3. Balance the oxides or chlorides or carbon

#4. Balance the hydrogen atoms.

That should get you started. If you're stumped on a particular equation, let me know.
