No.

Kw is a measure of power with units [ML2T-3] whereas 1.0*10-14 is a pure, dimensionless number. There can be no equivalence because the dimensions do not match.

Is 1014 equal?

1,014 = 1 x 1014, 2 x 507, 3 x 338, 6 x 169, 13 x 78, 26 x 39. It is an even number.


What is the pH of pure water at 313 K if Kw at that temperature is 2.917 x 10 -14?

Kw = [H+][OH-] [H+] = 10-pH = 10-6.17 For [OH-] remember that heat causes more water molecules to self-dissociate but for every new H+ generated, a OH- is generated as well. Therefore, the concentration of H+ and OH- is equal. [OH-] = 10-6.17 Kw = [H+][OH-] = 10-6.17 * 10-6.17 = 10-12.34

One light year is 5.88 x 1014 miles so if star 5A is 5.417 x 1014 miles from planet X how many light years is it from Planet x to star 5A?

5.88 x 1014 miles = 1 ly.1 mile = 1/5.88 x 1014 ly.5.417 x 1014 miles = 5.417 x 1014 /5.88 x 1014 ly = 0.9213 ly


An acid has Ka equals 2.5 x 10-4 what is the Kb for the conjugate base of this acid at 25C Kw equals 1.0 x 10-14 at 25C?

To find the Kb of the conjugate base, use the relationship Kw = Ka x Kb. Rearrange the equation for Kb: Kb = Kw / Ka = (1.0 x 10^-14) / (2.5 x 10^-4) = 4.0 x 10^-11.


An acid has Ka equals 3.1 x 10-10 What is the Kb for the conjugate base of this acid at 25 C?

To find the Kb of the conjugate base, you can use the relationship Kw = Ka * Kb. At 25°C, the value of Kw is 1.0 x 10^-14. Given Ka = 3.1 x 10^-10, you can solve for Kb using Kb = Kw / Ka. This gives you Kb = 1.0 x 10^-14 / 3.1 x 10^-10 = 3.23 x 10^-5.

An acid has Ka 3.1 10 10 What is the Kb for the conjugate base of this acid at 25 C Kw 1.0 10 14 at 25 C?

To find the Kb for the conjugate base, you can use the relationship Kw = Ka * Kb. Rearrange the equation to solve for Kb: Kb = Kw / Ka. Plugging in the values, you get Kb = (1.0 x 10^-14) / (3.1 x 10^-10) = 3.23 x 10^-5.


Is the value of Kw always 1.0 x 10-14?
