Question

1 mol of hydrocarbon P (contains C and H only) required 240 g of oxygen (O2) for complete combustion at standard state heat of combustion of P(l) is -3350 kJ/mol while heat of formation of CO2(g), H2O(l), and P(l) are -400kJ/mol, -300 kJ/mol and 50kJ/mol the molar mass of P is (in g/mol)​

Answer 1

Answer:

ok, here's the answer is

Explanation:

Heat Capacity

We now introduce two concepts useful in describing heat flow and temperature change. The heat capacity (C) of a body of matter is the quantity of heat (q) it absorbs or releases when it experiences a temperature change (ΔT) of 1 degree Celsius (or equivalently, 1 kelvin)

C=\dfrac{q}{ΔT} \label{12.3.1}

Heat capacity is determined by both the type and amount of substance that absorbs or releases heat. It is therefore an extensive property—its value is proportional to the amount of the substance.
