Acalorimeter was used to measure the heat change when an ionic compound dissolves in water. the final mass of the contents of the calorimeter was 50.70 g and the change in temperature was 2.00 °c. an insulated coffee cup is filled with a liquid and fully enclosed at the top, except for a small hole for a thermometer.

calculate the heat change of the calorimeter contents, given that its specific heat is 4.13 j/(g⋅°c.)
calculate the heat change of the calorimeter, given that its heat capacity is 7.0 j/°c.
calculate the heat change of the solution process.

The melting point of sulfur is 115 °c and its boiling point is 445 °c. what state would sulfur be in at 200 °c?

The equation below shows a chemical reaction. a + b + heat —> c + d according to the law of conservation of energy, which statement is true? a. the reactants absorb heat because they have less energy than the products. b. the products release heat because they have more energy than the reactants. c. the reactants generate heat because they have more energy than the products. d. the products require heat to form because they have less energy than the reactants.

Under what conditions will a gas be most likely to exhibit the ideal gas properties predicted by the ideal gas law? 1)high pressures and high temperature, because particles are forced closer together with higher kinetic energy, so intermolecular forces of attraction are weaker 2)high pressure and low temperature, because particles are forced closer together and moving slower, so the volume of the particles is less significant 3) low pressure and high temperature, because particles are spread farther apart and moving faster, so the intermolecular forces of attraction are weaker 4)low pressure and low temperature, because particles are spread farther apart with lower kinetic energy, so the volume of the particles is less significant
