A certain compound contains C, H and O. One molecule of the compound is known to contain 2 atoms of O, and the number of atoms of H is two times the number of atoms of C per molecule. when a quantity of the compound is burned completely in O2 to form CO2 and H2O as the only products, .375 mol of O2 is consumed and .3 mol of H2O is formed. Calculate the chemical formula of the compound.

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?
