| Which of the carbon oxides is the product of complete combustion of coal. Calculate how much oxygen is theoretically required for the complete combustion of 1 ton of coal.
1. Complete combustion is considered to lead to the production of carbon monoxide in the highest oxidation state, that is, carbon dioxide:
C + O2 = CO2;
2.For the convenience of calculations, let’s move from tons to grams:
1 t = 1000 kg = 10 ^ 6 g;
3.n (C) = m (C): Mr (C);
n (C) = 106: 12 = 8.3 * 10 ^ 4 mol;
n (O2) = n (C) = 8.3 * 10 ^ 4 mol;
4. V (O2) = n (O2) * Vm;
V (O2) = 8.3 * 10 ^ 4 * 22.4 = 185.92 * 10 ^ 4 = 1.86 * 10 ^ 6 dm3 = 1.86 * 10 ^ 3 m3.
Answer: 1.86 * 10 ^ 3 m3.
