bomb calorimeter contains 900.0 g of water after a 1.890 g sample of benzoic acid is burned (Heat of Reaction =−3227kJmol). If the temperature of the water increases 8.320∘C, what is the calorimeter constant in J∘C? The molar mass of benzoic acid is 122.12 g/mol. Use 4.184 Jg ∘C for the specific heat capacity of water.

The combustion of methane, ch4, releases 890.4kj/mol. that is, when one mole of methane is burned,890.4 kj are given off to the surroundings. this meansthat the products have 890.4 kj less than the reactants.thus, ah for the reaction = - 890.4 kj. a negative symbolforah indicates an exothermic reaction.ch (g) + 20 (g)> co2 (g) + 2 h0 (1); ah = - 890.4 kga) how much energy is given off when 2.00 mol of ch,are burned? b) how much energy is released when 22.4g of ch. areburned?
