Question 1

According to the following thermochemical equation, what mass of HF (in g) must react to produce 345 kJ of energy? Assume excess SiO2.

SiO2(s) + 4HF(g) → SiF4(g) + 2H2O(l)DrH° = -184 kJ

◦ 37.5 g
◦ 107 g
◦ 150. g
◦ 42.7 g
◦ 173 g

Question 2

According to the following thermochemical equation, what mass of H2O (in g) must form to produce 975 kJ of energy?

SiO2(s) + 4HF(g) → SiF4(g) + 2H2O(l)DrH° = -184 kJ

◦ 191 g
◦ 102 g
◦ 68.0 g
◦ 95.5 g
◦ 54.1 g
