    Heat of Combustion Question

    Heat 210g of water by 65ºC using ethanol specific heat capacity= 4.18 heat of combustion of ethanol = 1367KJ/mol ∆H=mc∆t = 210 x 65 x 4.18 = 57057 J (57.057 KJ) Since half heat is lost to surroundings, only 683.5 KJ/mol of heat was utilized from the ethanol. so 57.057/moles of ethanol =...
