Well to go from H+ to pOH, you have to convert H+ to pH first.

H+ = <span>7.5 x 10^-2

Formula to get pH = pH= -log(H+)
Plug H+ in: pH= -log(7.5x10^-2)

pH= 1.125

now to get pOH we convert pH to pOH

formula for pOH= pOH=14-pH
plug pH in: pOH= 14- 1.125


Answer: 12.875

Hope this helps :)</span>

What is Keq for the reaction N₂ + 3H2 = 2NH3 if the equilibrium
hram777 [196]

The Keq for the reaction N₂ + 3H2 = 2NH3 if the equilibrium concentrations are Keq = 1.5. The correct option is D.

<h3>What is Keq?</h3>

Keq is the ratio of the concentration of reactant to the concentration of the product.

The balanced equation is

N₂ + 3H₂  = 2NH₃

The equilibrium constant is \rm \dfrac{[NH_3]^2}{[N_2]\; [H_2]^3}

The given concentrations of the compounds have been:

Ammonia = 3 M

Nitrogen = 1 M

Hydrogen = 2 M

\rm \dfrac{9}{1\times 8} = 1.5

Thus, the correct option is D. Keq = 1.5.

The molecule CCI4 contains one double bond and three single bonds. True or False
kifflom [539]

False

Explanation: Carbon is the central atom which has valency of 4 and can form 4 bonds to complete its octet. Each chlorine has valency of 1 and can form only one bond to complete its octet. Thus carbon can bond with four chlorine atoms through sharing of electrons to form four single bonds. Thus it cannot contain a double bond.

I don't know your options but maybe this bit of information will help, the boiling point of water is 212<span>°</span>F so at that temperature it will likely just start evaporating

Calculate the eccentricity of an ellipse. The distance between the foci is 5.2 and the length of the major axis is 20.6.Round of
Dominik [7]

Answer:

The eccentricity of the ellipse is 0.252.

Explanation:

The eccentricity of an ellipse (c), dimensionless, can be determined by means of the following expression:

e = \frac{\bar c}{\bar a} (1)

Where:

\bar c - Distance between the foci, dimensionless.

\bar a - Length of the major axis, dimensionless.

If we know that \bar c = 5.2 and \bar a = 20.6, then the eccentricity of the ellipse is:

e = \frac{5.2}{20.6}

e = 0.252

The eccentricity of the ellipse is 0.252.
