Zn(s) + 2h +(aq) --> zn 2+(aq) + h2(g). a sample of zinc is placed in the ice calorimeter described in the \"experimental\" section below. if 0.0657g of zinc causes a decrease of 0.109ml in the ice/water volume of the calorimeter, what is the enthalpy change , per mole of zinc, for the above reaction per mole of zinc.. it is also given that enthalpy change for process h20(s) -> h20(l) is +6.01kj/mol or 333j/g and it can be determined that 3.68 kj are released per ml change in volume of ice/water mixture..

Calculate the estimated density of each ball. use the formula d = m/v where d is the density, m is the mass, and v is the volume. record your calculations in table a of your student guide. given that the density of water is 1.0 g/cm3, make a prediction about whether each ball will float in water. record your prediction in table a. what is the estimated density of the table tennis ball? record your answer to the nearest hundredth
