Balancing Equations P + + = O + + = GCSE/A Level Chemistry

P O + = + = Balancing Equations GCSE/A Level Chemistry Oxygen Hydrogen Water Oxygen Hydrogen P + = Oxygen Hydrogen Carbon O + = GCSE/A Level Chemistry

+ = Balancing Equations The mass on each side of the equation must be equal. Oxygen Carbon Dioxide Carbon + = 1 x 12 = 12g 2 x 16 = 32g 2 x 16 = 32g 1 x 12 = 12g + = 44g 12 32 GCSE/A Level Chemistry

= + Balancing Equations What happens if the masses are not equal/ Then the equation needs to be balanced. Carbon Monoxide Oxygen Carbon = + 2C 2 x 12 = 24g + O2 2 x 16 = 32g = 2CO 2 x 12 = 24g 24 + 2 x 16 = 32g 32 = 56g GCSE/A Level Chemistry
