If you have 2.86 gallons of pure water, how many molecules of water are ionized at any given time ?

Answer:

The molar mass of water is 18 grams per mole. So in 18 grams of water, there are 6.02 x 1023 molecules.

One gallon of water is equal to 3.7854118 liters. If we assume that the water is at 4 °C (to keep things simple), the density of water is exactly 1 gram per milliliter, or 1 kilogram per liter. So 1 gallon of water at 4 °C weighs exactly 3.7854118 kilograms, or 3785.41118 grams.

If one mole of water weighs 18 grams, then there are 210.30 moles of water in a gallon. Since one mole of water is made up of 6.02 x 1023 molecules, in one gallon of water there are 1.266 x 1026 molecules.

That is: 126600000000000000000000000 molecules!

If we multiply that by the number of atoms in a single water molecule -- 3 atoms -- then we get:

379800000000000000000000000 atoms!

For the reactions system 2H2(g) + S2(g) 2H2S(g), a 1.00 liter vessel is found to contain 0.50 moles of H2, 0.020 moles of S2, an
Mnenie [13.5K]

Answer: 1) 2H_2(g)+S_2(g)\rightleftharpoons 2H_2S(g)

Equilibrium constant is defined as the ratio of the product of concentration of products to the product of concentration of reactants each term raised to their stochiometric coefficients.

K_{eq}=\frac{[H_2S]^2}{H_2]^2\times [S_2]}

where [] = concentration in Molarity=\frac{moles}{\text {Volume in L}}

Thus [H_2S]=\frac{68.5}{1.0}=68.5M

[H_2]=\frac{0.50}{1.0}=0.50M

[S_2]=\frac{0.020}{1.0}=0.020M

K_{eq}=\frac{[68.5]^2}{0.50]^2\times [0.020]}=938450

As the value of K is greater than 1, the reaction is product favored.

2) N_2O_4(g)\rightleftharpoons 2NO_2(g)

K_{eq}=\frac{[NO_2]^2}{[N_2O_4]}

K_{eq}=\frac{[0.500]^2}{[0.0250]}=10

3) N_2+3H_2\rightleftharpoons 2NH_3

K_{eq}=\frac{[NH_3]^2}{[N_2]\times [H_2]^3}

4) Reactions which do not continue to completion are called equilibrium reactions as the rate of forward reaction is equal to the rate of backward direction.
