The pH would be 3.16 because the formula for finding the pH from a H± ion is pH = -log [H±]
So with that formula, you first have to substitute the H± with your numbers which in this case is 6.9 × 10^-4.
It should like this:
pH = -log (6.9 × 10^-4)
And lastly, just calculate.
pH = 3.16
Hope that helps, do let me know if you need more help in understanding this!
Answer:
3)The reaction is not at equilibrium and willproceed to the right.
Explanation:
The reaction quotient of an equilibrium reaction measures relative amounts of the products and the reactants present during the course of the reaction at particular point in the time.
It is the ratio of the concentration of the products and the reactants each raised to their stoichiometric coefficients. The concentration of the liquid and the gaseous species does not change and thus is not written in the expression.
Q < Kc , reaction will proceed in forward direction.
Q > Kc , reaction will proceed in backward direction.
Q = Kc , reaction at equilibrium.
Given that:
Q =
K =
Since, Q < K , reaction is not at equilibrium and will proceed to right, in forward direction.
Answer:
-149.0K
Explanation:
Charles's law states that the volume of a gas is directly proportional to the absolute temperature under constant pressure.
The equation is:
V1/T1 = V2/T2
<em>Where V1 is initial volume = 6.00L</em>
<em>T1 is absolute initial temperature = 25.0°C + 273 = 298K</em>
<em>V2 is final volume = 2.50L</em>
<em>T2 is our incognite</em>
<em />
Replacing:
6.00L/298K = 2.50L/T2
T2 = 2.50L * 298K / 6.00L
T2 = 124.17K
The temperature is 124.17K - 273.15K =
<h3>-149.0K</h3>

Answer:
It obeys rule
Explanation:
Benzene is an aromatic hydrocarbon because it obeys Hückel's rule.
It is unable to mske movement. It depends on the type of matter.
