Question

1)Refer to this equation:
3SCl₂ + 4NaF --> SF₄ + S₂Cl₂ + 4NaCl

64.0 grams SCl₂ is reacted with excess NaF and 12.5 grams of SF₄ is formed.

What is percent yield SF₄?
Hint: find theoretical yield
Hint: percent yield =(actual yield/ theoretical yield) x 100

		34.3 %
		64.4%
		38.0%
		27.8 %
		55.9 %
		92.1%
		36.1%
		24.6%

2)Consider the reaction of 7.92 grams of NH₃ and 12.3 grams O₂. What is the theoretical yield of NO in grams?
4NH₃ + 5O₂ -> 4NO + 6H₂O   
Hint: Find limiting reagent.

		9.23 g
		20.3g
		16.5g
		10.2g
		14.4g
		41.3g
		76.2g
		3.6 g
