Zinc metal reacts with hydrochloric acid according to the
Chapter 6, Problem 75E(choose chapter or problem)
Zinc metal reacts with hydrochloric acid according to the balanced equation:
When 0.103 g of Zn(s) is combined with enough HCl to make 50.0 mL of solution in a coffee-cup calorimeter, all of the zinc reacts, raising the temperature of the solution from 22.5 °C to 23.7 °C. Find rxn for this reaction as written. (Use 1.0 g/mL for the density of the solution and 4.18 J/g
°C as the specific heat capacity.)

QUESTION:
Zinc metal reacts with hydrochloric acid according to the balanced equation:
When 0.103 g of Zn(s) is combined with enough HCl to make 50.0 mL of solution in a coffee-cup calorimeter, all of the zinc reacts, raising the temperature of the solution from 22.5 °C to 23.7 °C. Find rxn for this reaction as written. (Use 1.0 g/mL for the density of the solution and 4.18 J/g
°C as the specific heat capacity.)
Solution 75E: Step 1 of 5 In general, the heat (q) required to raise the temperature of a sample is obtained by multiplying the heat capacity of the substance (C ) with mass of se substance (m) and temperature change (T) as given below: q = C ms .......... (1)
