7.0 g of nitrogen is reacted with 5.0 g of hydrogen to produce ammonia according to the chemical equation shown below. Which one of the following statements is false? N2(g) + 3 H2(g) → 2 NH3(g)options:3.5 g of hydrogen are left overAll of them are falseHydrogen is the excess reactant.Nitrogen is the limiting reactant.The theoretical yield of ammonia is 15 g.

Sagot :

Step 1

N2(g) + 3 H2(g) → 2 NH3(g) (must be balanced)

The limiting reactant

Data needed:

The molar mass:

For N2) 28 g/mol

For H2) 2 g/mol

For NH3) 17 g/mol

Procedure:

28 g N2 ------ 3 x 2 g H2

7.0 g N2------- X = 1.5 g H2

According to this, for 7.0 g N2, 1.5 g H2 is needed to react, but 5.0 g is provided. Therefore, H2 is the excess, and N2 is the limiting reactant

1.5 g of H2 is reacted, so 5.0 g - 1.5 g= 3.5 g are leftover

------------------

Step 2

The theoretical yield.

Procedure:

28 g N2 ------ 2 x 17 g NH3

7.0 g N2------ X = 8.5 g NH3

Answer: The theoretical yield of ammonia is 15 g. FALSE
