Answer:

D. The concentrations of N2, H2, and NH3 would remain the same.

Explanation:

  • In reversible reactions, equilibrium is a point in which the rate of forward reaction is equal to that of reverse reaction.
  • Given the equation;

N₂(g)+ 3H₂(g) → 2NH₃(g) is a equilibrium at a constant volume of 1.0 L

  • Addition of Argon gas which an inert gas dose not affect the equilibrium of the reaction.
  • This is because the addition of an inert gas at constant volume only causes an increase in the total pressure of the system while the concentrations of the reactants and products remain constant, therefore not affecting the equilibrium.

A sample of 0.370 mol of a metal oxide (m2o3) weighs 55.45 g. how many grams of o are in the sample?
Wewaii [24]
0.370 mol metal oxide = 55.45 g 

<span>1 mol = 55.45/0.370 = 149.86 g </span>

<span>in 1 mol there are 3 mol O = 16 * 3 = 48 g of O </span>

<span>there is 48/149.86 * 100% O in the sample </span>

<span>the sample has 48/149.86 * 0.370 = 0.119 g O</span>

2Al+3Cl2⟶2AlCl3
Leviafan [203]

Answer:

7.335 moles of  Cl₂ are required to react with 4.89 miles of Al.

Explanation:

Given data:

Moles of Al = 4.89 mol

Number of moles of Cl₂ required = ?

Solution:

Chemical equation:

2Al + 3Cl₂    →   2AlCl₃

Now we will compare the moles of Al and chlorine from balance chemical equation.

                            Al           :         Cl₂

                             2           :           3

                            4.89      :         3/2×4.89 =7.335 mol

Thus, 7.335 moles of  Cl₂ are required to react with 4.89 miles of Al.
