Cu + CO2
Balance the above reaction by writing in the correct coefficient.

Answer 1

2CU2O + C -----> 2Cu + CO2

Step-by-step explanation:

2 is added in reactants to balance oxygen O on both sides and 2 before Cu is added in products to balance Cu on both sides.

Answer 2

2 Cu2O + C = 4 Cu + CO2

Step-by-step explanation:

CU2O has 2 coefficient

C has 1 coefficient

Cu has 4 coefficient

CO2 has 1 coefficient

Balance Equation 2 Cu2O + C = 4 Cu + CO2
