Zinc metal reacts with hydrochloric acid according to the balanced equation: Zn(s) + 2 HCI(aq) -> ZnCl,(aq) + Hz(g) When 0.103 g of Zn(s) is combined with enough HCI 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 AH 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.)| Ans: -1.6 x 10' kJ/mol
Chap 6: Thermochemistry 1. What mass of natural gas (CH.) must burn to emit 267 kJ of heat? CH,(g) + 2 0,(g) CO,(g) + 2 H,O(g) -802.3 kJ Ans: 5.34g
