Question

5. Will a salt dissolve in a nonpolar solvent? 6. Ammonia NH3, can be synthesized by the following reaction: 2NO+ 5H22NH3 +2 H2O If you start with 90.0 grams of NO and an unlimited supply of H2, what is the theoretical yield of ammonia? How much water is produced? 7. What is the percent yield if 25 grams of ammonia are produced? 8. If 5 grams of product are produced out of a possible 15 grams, what is the percent yield of that product?

Answer 1

5)
Salt is ionic in nature.
They will dissolve in polar solvent.
They will not dissolve in non polar solvent.
Answer: No

6)

Molar mass of NO,
MM = 1*MM(N) + 1*MM(O)
= 1*14.01 + 1*16.0
= 30.01 g/mol

mass of NO = 90 g
mol of NO = (mass)/(molar mass)
= 90/30.01
= 2.999 mol

According to balanced equation
mol of NH3 formed = moles of NO
= 2.999 mol


Molar mass of NH3,
MM = 1*MM(N) + 3*MM(H)
= 1*14.01 + 3*1.008
= 17.034 g/mol


mass of NH3 = number of mol * molar mass
= 2.999*17.03
= 51.1 g

According to balanced equation
mol of H2O formed = moles of NO
= 2.999 mol


Molar mass of H2O,
MM = 2*MM(H) + 1*MM(O)
= 2*1.008 + 1*16.0
= 18.016 g/mol


mass of H2O = number of mol * molar mass
= 2.999*18.02
= 54.0 g

Answer:
Mass of NH3 = 51.1 g
mass of H2O = 54.0 g
