Question 1

How many grams of calcium hydride are required to produce 4.56 L of hydrogen gas at 25.0 °C and 0.975 bar according to the chemical equation shown below?

CaH2(s) + 2H2O(l) → Ca(OH)2(aq) + 2H2(g)

◦ 7.64 g
◦ 45.6 g
◦ 3.77 g
◦ 15.3 g

Question 2

How many molecules of XeF6 are formed from 12.9 L of F2 (at 298 K and 2.635 bar) according to the following reaction? Assume that there is excess Xe.

Xe(g) + 3F2(g) → XeF6(g)

◦ 7.29 × 1023 molecules XeF6
◦ 8.25 × 1023 molecules XeF6
◦ 1.21 × 1023 molecules XeF6
◦ 2.75 × 1023 molecules XeF6
