Question
In the diagram above the paired open spheres represent H2 molecules and the paired solid spheres represent N2 molecules. When the molecules in the box react to form the maximum possible amount of ammonia (NH3) molecules, what is the limiting reactant and how many molecules of NH3 can be formed9 (A) N2 is limiting. 5 molecules of NH3 can be formed. (B) N2 is limiting, 10 molecules of NH3 can be formed. (C) H2 is limiting. 8 molecules of NH3 can be formed. (D) H2 is limiting.12 molecules of NH3 can be formed. Vanillin, C8H8O3 (M= 152 g/mol), is the molecule responsible for the vanilla flavor in food. How many 8.Which one of the following cannot act as an oxidizing agent? 9.Which substance is the primary component in stalactites and stalagmites in caves? 10.Five successive determinations of the density of an alloy gave the following results: 10.29 g/mL, 9.95 g/mL, 10.06 g/mL, 9.89 g/mL, 10.18 g/mL What value should be reported for the density of this alloy?Explanation / Answer
N2 + 3H2 ------------> 2NH3
Hence for one molecule of Nitrogen we need 3 molecules of Hydrogen
There are 5 Molecules of nitrogen and 12 molecules of hydrogen.
for 5 Molecules of nitrogen we need 15 molecules of hydrogen. But 12 molecule of Hydrogen only present here. hence Hydrogen molecule is limiting reagent.
As well 4 molecule of Nitrogen only can react and give 8 molecule of ammonia
Finally answer is
C) Hydrogen molecule is limiting reagent and 8 molecule of ammonia will be formed
