Answer to Question #212350 in General Chemistry for kylee mulligan

Question

1) What is the limiting reactant if 43.4 g of NH₃ react with 30 g of NO? The balanced equation is 4NH₃ + 6NO --> 5N₂ + 6H₂O.

2) If a reaction takes place and the theoretical yield is 73 g and the actual yield is 62 g, Calculate the percent yield.

3) How many grams of NO are formed if 8.3 g of ammonia react with 11.8 g of oxygen? The reaction is 4NH₃ + 5O₂ --> 4NO + 6H₂O.

4) What is the percent yield if 0.856 g of NO is actually obtained in the lab during the following reaction: 4NH₃ + 5O₂ --> 4NO + 6H₂O . 6.3 g of Ammonia was reacted with 1.8 g of Oxygen?

Answer 1

1). 6NO

2). Percentage yield = (Actual/Theoretical) × 100

= 62/73 × 100= 86.3%
