100 ml of a 0.300 m solution of agno3 reacts with 100 ml of a 0.300 m solution of hcl in a coffee-cup calorimeter and the temperature rises from 21.80 °c to 23.20 °c. assuming the density and specific heat of the resulting solution is 1.00 g/ml and 4.18 j/g ∙ °c, respectfully, calculate how much heat (q) was released
