How much heat is produced when `4.50g` methane gas is burnt in a constant pressure system ?
Given `:CH_(4)+2O_(2)rarr CO_(2)+2H_(2)O,DeltaH=-8.2kJ`

Calculate heat of formation of water at constant volume at 300 K. Given that: H_(2(g))+1/2O_(2(g))rarr H_2O_(l) DeltaH=-284.2kJ

The heat evolved in the combustion of methane is given by the following equation : CH_(4)(g)+2O_(2)(g)to CO_(2)(g)+2H_(2)O(l) , Delta H = -890.3 kJ How many grams of methane would be required to produce 445.15 kJ of heat of combustion ?
