50.0 mL of water at 40.5 °C is added to a calorimeter containing 50.0 mL of water at 17.4
°C. After waiting for the system to equilibrate,
the final ternperature reached is 28.3 °C.
Calculate the heat capacity of the calorimeter.
(S. H of water == 4.184 J/gX°C)?

What volume of a 2.00 m stock solution of naoh is needed to prepare 150. ml of 0.40 m solution?

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

Why dose heating increase the speed at which a solution dissolved in water
