Answer to Question #130181 in General Chemistry for Mary

Question

When a solution of KOH is neutralized by hydrochloric acid, the solution gets hot.

Calculate the change in heat of the solution (in J).

Mass of combined solution = 42.0 g

Temperature change of the solution = 13.4 K

Specific heat capacity of the solution = 4.18 J/g·K

Give your answer to three significant figures.

Answer 1

Q=cmΔt=4,18*42*13,4=2350 J
