Question- A paper cup is filled with water (enthalpy of vaporization for water is 40.65 kJ/mol). The activation energy for the ignition of the paper is 470 kJ. The cup holds 200.0 mL of water. Assume that the specific heat capacity of the paper is 0 J K-1 g-1 while that of water is 4.184 J K-1 g-1. A butane (C4H10) container has 20.0g of gas in it and is used to heat the paper cup with water. The enthalpy of combustion of butane is -2877.5 kJ/mol.

1. Determine the amount of heat required to heat the water to 100 °C, assuming it starts at 25 °C?

2. Determine the amount of heat require to vaporize the water

3. If the butane is all burnt, will the paper catch alight (assuming that any water present will prevent the paper from burning)?

I want to know how this is done please show all steps in detail
