The correct answer of equilibrium concentration of BrCl is 0.2292 M.
The balanced chemical equation:
Br2(g) + Cl2(g) = 2BrCl(g)
[Br2] = [Cl2] = (0.2 - x) M
[BrCl] = (2x) M
7.20 = [2x / (0.2 - x)]2
2.6833 = 2x / (0.2-x)
2.6833 × (0.2 - x) = 2x
0.53666 - 2.6833x = 2x
0.53666 = 4.6833x
x = 0.1146
[Br2] = [Cl2] = 0.2 - x = 0.2 - 0.1146 = 0.0854 M
[BrCl] = 2x = (2 × 0.1146) = 0.2292 M
[BrCl] = 0.2292 M

What is equilibrium concentration?</h3>
A chemical reaction is considered to be in a state of chemical equilibrium when both the reactants and the products are in a concentration that does not change over time any more. The forward response rate and the backward reaction rate are equal in this condition. You can determine the equilibrium concentration for a reaction if you know the starting concentrations of the constituent chemicals.

Answer:
12 amu or 12 g.
Explanation:
One mole of 12C = one 12c atom. The mass of one carbon-12 atom is 12.000 amu.
Answer:
1.45 mol
Explanation:
Given data
- Volume of the gas (V): 8.77 L
- Temperature of the gas (T): 20 °C
- Pressure of the gas (P): 3.98 atm
Step 1: Calculate the absolute temperature (Kelvin)
We will use the following expression.
Step 2: Calculate the number of moles (n) of the gaseous sample
We will use the ideal gas equation.
