When a 0.3445 gram sample of solid calcium (ca) was burned in a constant-volume calorimeter (bomb calorimeter) with a measured heat capacity of 0.1975 kj/°c, the temperature of the calorimeter increased by 27.63°c. (a) calculate the change of heat released by the combustion of the calcium sample. kj (b) determine the change of heat that would be released by the combustion of 1 mole of calcium.

For each of the following compounds, write the formula then predict whether it would be a strong, weak, or non-electrolyte when placed in di water. for the ionic compounds only, put (s) or (aq) after the forrmula formula strong, weak or non electrolyte? a calcium hydroxide b. silver carbonate c. lead(ii) sulfate d. phosphorus trifluoride e. sodium phosphide f barium sulfate g. strontium acetate h. zinc nitrate
