If the molecules in the above illustration react to form NH3 according to the equation N2 3 H2 2 NH3 , the limiting reagent is ,
Kamila [148]

Answer:

Follows are the solution to these question:

Explanation:

Given equation:

N_2+3H_2 \longrightarrow 2NH_3

In this equation:

1 N_2 gives = 2NH_3

so,

3N_2 gives=  2 \times 3 = 6 NH_3

similarly:

3H_2 gives = 2NH_3

So, 6H_2 gives = \frac{2}{3}\times 6=4NH_3

Its limited reagent is =N_2

The amount of NH_3 molecules were formed = 4.

and the amount of  H_2 excess molecules are= 1

Copper (II) oxide can be heated until it decomposes into elemental copper and oxygen gas. Is 0.695 grams of Copper (II) oxide is
insens350 [35]

Answer:

0.55 g of Cu can produced by this decomposition

Explanation:

Let's think the reaction of decomposition:

2CuO → 2Cu + O₂

Ratio is 2:2. 2 moles of CuO can decompose into 2 moles of Cu and 1 mol of oxygen.

Let's convert the mass of oxyde to moles → 0.695 g. 1 mol/ 79.55 g =

8.74×10⁻³ moles

8.74×10⁻³ mol of CuO decompose to 8.74×10⁻³ moles of Cu

Let's find out the mass → 8.74×10⁻³ mol . 63.55 g/1mol = 0.55 g
