Calorimetry NOT DONE

What is Calorimetry used for?

To measure the amount of heat transferred to or from a substance

What is a Calorimeter?

An appartus that measures the amount of heat involved in a chemical or physical process.

If heat produced by the reaction is absorbed by the solution is it Exothermic, or Endothermic?

Exothermic

If heat provided by the reaction is provided by the solution is it Exothermic, or Endothermic?

Endothermic

What does q_soln represent?

Heat gained by the solution

What does q_rxn represent?

Heat produced by the reaction

Heat gained by the solution (q_soln) is equal in magnitude to __ but opposite in sign

q_rxn

What What is bomb calorimetry used to measure?

The energy produced by reactions that yield large amounts of heat and gaseous products.

A student dissolves 5.00 g of CaCl_2(s) in 100.0 g of water in a coffee-cup calorimeter. The water temperature rises from 22.4 to 28.9 degrees Celsius. Assume the solution's specific heat is the same as water (4.184 J/g * degrees Celsius). A.) Calculate the heat absorbed by the water. B.) Determine the heat released by the reaction.

(Hint: Heat absorption)

A.) q = c * m * (uppercaseDelta)T

q = (4.184 J/g degrees celsius) * 100 × (28.9-22.4)

q = 2720 J

B.) q = 2720 J

q_rxn = -2720 J
