Answer:

1. 10.8 g of NO

2. N₂ is the limting reagent

3. 3.2 g of O₂ does not react

Explanation:

We determine the reaction: N₂(g) + O₂(g) →  2NO(g)

We need to determine the limiting reactant, but first we need the moles of each:

5.04 g / 29 g/mol = 0.180 moles N₂

8.98 g / 32 g/mol = 0.280 moles O₂

Ratio is 1:1, so the limiting reactant is the N₂. For 0.280 moles of O₂ I need the same amount, but I only have 0.180 moles of N₂

Ratio is 1:2. 1 mol of N₂ can produce 2 moles of NO

Then, 0.180 moles of N₂ may produce (0.180 .2) / 1 =  0.360 moles NO

If we convert them to mass → 0.360 mol . 30 g/1 mol = 10.8 g

As ratio is 1:1, for 0.180 moles of N₂, I need 0.180 moles of O₂.

As I have 0.280 moles of O₂, (0.280 - 0.180 ) = 0.100 moles does not react.

0.1 moles . 32 g/mol = 3.2 g of O₂ remains after the reaction is complete.

Answer:

(a) 10.8 grams of nitrogen monoxide

(b) The formula for the limiting reagent is N

(c) 3.22 grams of the excess reagent remains

Explanation:

(a) The equation of reaction involves the reaction of 2 moles of nitrogen atom (N) and 1 mole of oxygen molecule (O2) to form 2 moles of nitrogen monoxide (NO).

From the equation of reaction above,

2 moles of nitrogen atom (28 grams) produced 2 moles of nitrogen monoxide (60 grams)

5.04 grams of nitrogen would produce (5.04×60)/28 = 10.8 grams of nitrogen monoxide.

(b) 1 mole of oxygen (32 grams) reacted with 2 moles of nitrogen (28 grams)

8.98 grams of oxygen would be required to react with (28×8.98)/32 = 7.86 grams of nitrogen but only 5.04 grams is available. Therefore, the limiting reagent is nitrogen atom and its formula is N.

(c) 2 moles of nitrogen monoxide (60 g) are produced from 1 mole of oxygen (32 g)

10.8 g of nitrogen monoxide is produced from (10.8×32)/60 = 5.76 grams of oxygen but 8.98 grams of oxygen is available. Therefore, oxygen is the excess reagent.

Mass of excess reagent that remains after the reaction is complete = 8.98 - 5.76 = 3.22 grams
