A 75.0 g sample of granite initially at 92.5oC is immersed into 60.0 g of water initially at 22.2oC. Determine the final temperature (in oC) when they reach thermal equilibrium. Assume no heat loss to the surroundings. Specific heats: granite = 0.790 J/(goC), water = 4.184 J/goC

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
