Solution: Balance the following equation:CaO (s) + C (s) → CaC2 (s) + CO2 (g)

Solution: Balance the following equation:CaO (s) + C (s) → CaC2 (s) + CO2 (g)

Problem

Balance the following equation:

CaO (s) + C (s) → CaC2 (s) + CO2 (g)

Solution
  • For the equation CaO (s) + C (s) → CaC2 (s) + CO2 (g), we have to balance O first, then Ca and lastly C
  • Usually, we balance diatomic or monoatomic molecules lastly (C in this case)
  • Balance O (2 on both sides)

2CaO (s) + C (s) → CaC2 (s) + CO2 (g)
