The pOH of a solution is 6.0. Which statement is correct?
I am Lyosha [343]

Answer : Option D) The pH of the solution is 8.0.

Explanation : pOH of a solution is a measure of hydroxide ion (OH^{-}) concentration in a particular solution. It gives the measure of alkalinity of a solution. Normally, aqueous solutions at 25°C have pOH which is less than 7 are usually alkaline, when pOH is found to be greater than 7 then they are acidic and when pOH will be equal to 7 then it is neutral.

pH + pOH = 14, this relationship is used to find pH of any unknown solution with given pOH value,

Here, we known pOH is 6.0, so we get,

pH = 14 - 6 = 8.0;

Hence, the pH will be 8.0.

draw two lewis structures for a compound with the formula c2h6o and compare the boiling points of the two molecules
Volgvan

Answer:

See explanation and images attached

Explanation:

There are two compounds that could have molecular formula of C2H6O, they are ethanol and methoxy methane (trivial name: methyl ether).  The structures of the two compounds are shown in the image attached as obtained from quora.

The boiling point of methoxymethane is -24.8°C  while that of ethanol is about 78.5°C. The reason for the high boiling point of ethanol is the presence of intermolecular hydrogen bonding leading to a stronger intermolecular interaction compared to methoxymethane molecules held together only by very weak dispersion forces.

Consider the reaction: 2N2O(g) ⇌ O2(g) + 2N2(g). Which of the following will cause a shift in the equilibrium to the right? 1. A
Illusion [34]

Answer:

1. Add N2O and

3. Remove N2

Explanation:

In equilibrium, there is a balance between the concentrations of the reactants and products. If more reactants are added, the equilibrium will shift to the right, favoring the forward reaction. This cause an increase in the concentration of the product and the equilibrium constant is unchanged.

Products can also be removed in order to increase the amount of products formed, forward reaction. This shifts the equilibrium to the right.

In the reaction 2N2O <-----> O2 + 2N2, adding N2O to the mixture favors the forward reaction and more products are formed, equilibrium shifts to the right.

Also, removing the product formed favors the forward reaction as more products will be formed in order to achieve equilibrium. The equilibrium therefore shifts to the right.
