Question no. 1 and 3 please explain

Numerical Answer Type 1022 C neat OI Combustion of carbon is 394 kI/mol. The heat evolved in combustion of b.023 * IU atoms of carbon is k ar or S, 1S-297.5 kJ mol-. The energy required for the decomposition of 32 g of SO, (1n kJ) is: wO moles of an ideal gas at 2 bar and 27°C expand isothermally against a constant pressure of l bar. What is the work done by the gas? 2 3 4 Given that

See Reshav Buddy, the heat of combustion is given for one mole of Carbon and the given number of Carbon atoms is 0.1 mole of carbon. (You can easily divide it by Avogadro's number and find the moles). So, if 1 mole correspondens to 39.4 kJ. 0.1 mole will correspond to 3.94 kJ.
