Answer:
1.89 × 10^-11 M
Explanation:
Recall that;
[H^+] [OH^-] = 1 × 10^-14
[H^+] = concentration of hydronium ions
[OH^-] = concentration of hydroxide ion
Where [OH^-] = 5.3 × 10−4 M
[H^+]= 1 × 10^-14/5.3 × 10−4
[H^+]= 1.89 × 10^-11 M
- The reaction in which we can't take back the product to reactant form .Or in simple words the reaction which is irreversible is called chemical reaction
Example:-
We cannot pull back the reaction to get wax back .
We use the formula:
ΔP = (ΔH / ΔV) ln(T2 / T1)
where,
ΔH = change in enthalpy from solid to liquid = 4810 J/mol
ΔV = change in volume from solid to liquid = 0.55 cm^3/mol
T2 = 620 K, T1 = 600 K
So,
ΔP = (4810 / 0.55) ln(620 / 600)
ΔP = 286.76 J/cm^3
or converting to atm:
<span>ΔP
= 2830 atm</span>
Answer:
Supersaturated solutions
Explanation:
These are the solution which contain more solute than its ability at high temperature.
They comtain more solute concentration than at the normal conditions.
Answer:
I think that temperature will be cut in half.
When volume increases, pressure decreases. As pressure decreases, temperature decreases. So if you double volume, pressure is halved and so will the temperature. I'm new to this, but I think that's the answer . Tell me if I'm right good luck!
