Question

Assignment

1. If 5.26 L of nitrogen monoxide and 7.64 L of oxygen are combined. What mass of nitrogen dioxide will formed? 2NO + O₂ → 2NO₂

2. 46.1 g of cesium and 13.4 g oxygen reacted-to form 28.3 g of cesium oxide. Which reactant was the limiting reactant? What was the percent yield of this reaction? 4 Cs + O₂ → 2 Cs₂O

3. 28.1 g of tetraantimony hexoxide reacted with enough carbon to form 17.3 g of antimony. What was the percent yield of this reaction? Sb₄O₆ + 6C → 4 Sb + 6 CO
