Question

Сколько литров углекислого газа(при н.у.)образуется при горении 1 кг углерода?

Answer 1

C + O2 = CO2
J(C)= 1000 г/ 12 г/моль =83,3 моль
J(C)=J(CO2)
V(CO2)=J*Vm=83,3 моль*22,4 л/моль= 1865, 92 л

Answer 2

Amount of Carbon Dioxide Produced by Burning 1 kg of Carbon

When 1 kg of carbon is burned, it produces 3.67 cubic meters (m³) or 3670 liters of carbon dioxide at standard temperature and pressure (STP).

This information is based on the chemical reaction for the combustion of carbon, which can be represented as:

C + O2 → CO2

The balanced chemical equation shows that 1 mole of carbon reacts with 1 mole of oxygen to produce 1 mole of carbon dioxide. From this, the molar volume of a gas at STP (22.4 liters) can be used to calculate the volume of carbon dioxide produced when 1 kg of carbon is burned.
