Answer: CH4 + 2 O2 = CO2 + 2 H2O

           Reaction type: combustion

            CaCl2 + 2 AgNO3 = 2 AgCl + Ca(NO3)2

            Reaction type: double replacement

           C2H6O + 3 O2 = 2 CO2 + 3 H2O

               Reaction type: combustion

Explanation: Happy to help

the last one cant be balanced without changing the coefficiant on the C2H6O and it looks like there isnt a box there
