When:
Fe(OH)3 ↔
Fe3+ + 3OH-so, each 1 mol Fe3+ → 3 mol OH-
and when [OH]
= 1.2 x 10^-5∴ [Fe3+] = (1.2 x 10^-5) / 3
= 4 x 10^-6when
Keq = [Fe3+][OH]^3 = (4 x 10^-6) (1.2 x 10^-5)^3
∴Keq = 6.9 x 10^-21
Answer:
The first one is 102.33 g/ml
Explanation:
307 divided by 3 gets u the answer 102.33(repeated)
Hope this helps :)
Gravity
Explanation:
The unpowered cars as shown gets their potential energy from their acceleration due to gravity and the height above the ground of the hill.
Potential energy is the energy due the position or a body. It is energy primarily at rest of a body.
Potential energy = m x g x h
Where:
m = mass
g = acceleration due to gravity
h = height of the hill.
