What temperature will the water reach when 10.1 g cao is dropped into a coffee cup containing 157 g h2o at 18.0°c if the following reaction occurs? cao(s) + h2o(l) → ca(oh)2(s) δh°rxn = –64.8 kj/mol assume that the cup is a perfect insulator and that the cup absorbs only a negligible amount of heat. (the specific heat of water = 4.18 j/g·°c)
