Coal is mostly carbon (C). When it is burned, it reacts with oxygen in the air in a combustion reaction. 43% of the electricity generated uses coal. On average, each person uses 2680 kg of coal per year to generate electricity that they use.
How much CO2 is produced?
The molar masses are:
C - 12.01 g/mol = 0.01201 kg/mol
CO2 - 44.01 g/mol = 0.04401 kg/mol
The reaction equation is:
C + O2 --> CO2
Answer: 9820 kg
