Help write balanced equation for these

1.) Methane gas burns in air to form carbon dioxide and water.

2.) Solutions of ammonium chloride and sodium hydroxide react to form solid sodium chloride and aqueous ammonium hydroxide.

3.) Magnesium metal reacts with sulfuric acid [ H(2)SO(4) ] to form solid magnesium aulfate and hydrogen gas.


Please write (parenthesis) for the subscript.

1) CH(4) + 2O(2) --> CO(2) + 2H(2)O
This is a combustion reaction
2) NH(4)Cl + NaOH --> NaCl + NH(4)OH
Double replacement reaction
3) Mg + H(2)SO(4) --> MgSO(4) + H2

By the way, parentheses are normally reserved for the state of the compounds (i.e. solid, liquid or gas), using parentheses for the subscript makes it hard to understand what state the compound it's in.

1. CH(4) + 2O(2) ---> CO(2) + 2H(2)O

2. Already balanced: NH(4)Cl + Na[OH] ----> NaCl + NH(4)[OH]

3. Already balanced: Mg + H(2)SO(4) -----> MgSO(4) + H(2)

1 CH(4) + 2O(2) --> CO(2) + 2H(2)O
2 NH(4)Cl + NaOH --> NaCl + NH(4)OH
3 Mg + H(2)SO(4) --> MgSO(4) + H2...
