How much CO2 is produced on heating of 1 kg of carbon ?
Explanation
The correct answer is Option 1. To determine the amount of CO2 produced, we use the stoichiometry of the combustion reaction: C + O2 → CO2.
In this reaction:
- Atomic mass of Carbon (C) = 12 units.
- Molecular mass of Oxygen (O2) = 32 units (16 × 2).
- Molecular mass of Carbon Dioxide (CO2) = 12 + 32 = 44 units.
According to the law of conservation of mass, 12 kg of Carbon reacts with 32 kg of Oxygen to produce 44 kg of CO2. Therefore, to find the CO2 produced from 1 kg of Carbon, we calculate the ratio: 44 / 12, which simplifies to 11/3 kg (approximately 3.67 kg).
Option 1 represents this stoichiometric derivation. Options 2, 3, and 4 are incorrect as they do not align with the chemical mass-balance required for the complete combustion of carbon.
