Thermochemistry practice problem
A 5.00-g sample of aluminum pellets (specific heat capacity "
0.89 J/'C ! g) and a 10.00-g sample of iron pellets (specific heat
capacity " 0.45 J/'C ! g) are heated to 100.0'C. The mixture
of hot iron and aluminum is then dropped into 97.3 g water at
22.0'C. Calculate the final temperature of the metal and water
mixture, assuming no heat loss to the surroundings.
