Answer : The value of equilibrium constant (K) is, 424.3
Explanation : Given,
Concentration of at equilibrium = 0.067 mol
Concentration of at equilibrium = 0.021 mol
Concentration of at equilibrium = 0.040 mol
The given chemical reaction is:
The expression for equilibrium constant is:
Now put all the given values in this expression, we get:
Thus, the value of equilibrium constant (K) is, 424.3
Automobiles have they highest cost for of pollution in the air
Answer:
0.6522 mol/L.
Explanation:
<em>Molarity is defined as the no. of moles of a solute per 1.0 L of the solution.</em>
<em />
M = (no. of moles of solute)/(V of the solution (L)).
<em>∴ M = (no. of moles of solute)/(V of the solution (L)) </em>= (1.5 mol)/(2.3 L) = <em>0.6522 mol/L.</em>
The answer is A. The vibration caused by the waves through the air eventually weaken, which is why sound diminishes easily over distance.
