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.

#SPJ4
3.88 atm is the pressure in atm, given that there are 1.45 moles of gas in the sample.
Explanation:
Given that:
Volume of the gas sample V = 8.77 litres
temperature of the gas sample T = 20 degrees OR 293.15 K
number of moles of the gas = 1.45
R (Gas constant) = 0.08021 L.atm/mole K
Pressure of the gas = ?
The equation for ideal gas will be used here to calculate the pressure of the gas:
PV = nRT
the equation is rewritten as:
P=
P =
P = 3.88 atm
1.45 moles of the gas at given conditions would have pressure of 3.88 atm.
The answer is
D) Betsy is correct since the line is the same on both graphed and both objects are traveling at a speed of 6.25 meters per second.
Answer:
D
Explanation:
Diffusion is directly propotional to temperature i.e. if the temperature is hight diffusion is more and vice versa
Moreover, diffusion is inversely propotional to size i.e. if molecules are large , diffusion is less and vice versa
Answer:
94.44
Explanation:
Volume is equal to Mass/Density so therefore, you do the mass which is 68.0 g/0.72 g/mL which is the density and get 94.44 mL because the g cancel each other out when it comes to the label!
