0.50 g of magnesium is placed in a foam cup calorimeter containing 100. mL of 1 M HCl at 25.0ºC. The
solution reaches a temperature of 47.6ºC. How many joules of heat were released by the reaction of
magnesium with HCl?
For calculations, ignore the mass of the magnesium. Assume that HCl is primarily
water and has the same specific heat as water and has a density of 1.00 g/mL.
