in a reaction 35.0 mL of 0.718 M copper II chloride reacts with 45.0 mL of 0.429 M potassium phosphate. Determine the molarity of each of the spectator ions.
A 350g sample of an unknown solid is heated continuously from 10°C to 75°C. Scientists determine that the energy change during that process is 4,860J. If the solid does not change phase during the heating process, what must its specific heat capacity be?
1.20 grams of sodium carbonate reacts with 1.9 grams of calcium chloride dihydrate to form sodium chloride and calcium carbonate in a double replacement type reaction.
1) calculate with reactant is the limiting reactant. Show the work and label which reactant is limiting.
2) once you know which is the limiting reactant, calculate the amount of calcium carbonate which can be made.
3) once you know the limiting reactant, calculate the amount of sodium chloride which can be made.

According to the kinetic molecular theory, if two different gas molecules were at the same temperature and pressure, but one molecule was large and the other was small, which molecule would have the greatest kinetic energy?
What volume of gas would you expect to collect during an experiment if 1.5-moles of carbon dioxide were produced at 35⁰C and 113 kPa?
What volume of gas would you expect to collect during an experiment if 1.5-moles of carbon dioxide were produced at 35⁰C and 113 kPa?
write balanced chemical equations for each, remember to make your molecules neutral first.
Sodium iodide and potassium hydroxide form when aqueous iodide is mixed with sodium hydroxide solution.
A tire contains a mixture of gases with a total pressure of 245.0 torr. If the partial pressures of the oxygen, carbon dioxide, and nitrogen gases it contains are 51.3 torr, 0.10 torr, and 191.3 torr, respectively, what is the remaining partial pressure of the argon gas?
