Question 1

Consider the equation:

2 Na + 2 H₂O → 2 NaOH + H₂
If 92.0 g of sodium is reacted with 76.0 g of water until the reaction goes to completion, which reactant will remain and in what quantity?
◦ 72.0 g water
◦ 43.5 g sodium
◦ 3.9 g water
◦ 10.0 g sodium
◦ 10.0 g water

Question 2

Consider the gaseous reaction:

N₂H₄(g) + 3 O₂(g) → 2 NO₂(g) + 2 H₂O(g)

If the above reaction has a percent yield of 98.5%, what mass in grams of oxygen is needed to produce 49.0 g of NO₂(g), assuming an excess of N₂H₄?
◦ 50.4 g
◦ 51.9 g
◦ 25.9 g
◦ 23.1 g
◦ 11.5 g
