Answer:

HBrO forms hydrogen bonds with each other and with water

Acetic acid forms hydrogen bonds with each other and with water

Formaldehyde can't form hydrogen bonds to each other but do form hydrogen bonds with water.

Explanation:

The hypohalous acids are polar molecules hence they form intermolecular hydrogen bonds. They also form hydrogen bonds with water. This enables it to dissolve in water.

Acetic acid can form dimmers with each other due to hydrogen bond formation. Also, acetic acid is capable of forming hydrogen bonds with water. This enables acetic acid to dissolve in water.

Aldehydes do not form intermolecular hydrogen bonds with each other because there is no hydrogen atom attached directly to oxygen in aldehydes. As such, they can only form hydrogen bonds with water. This accounts for the water solubility of low molecular weight aldehydes. Hence,  formaldehyde can't form hydrogen bonds to each other but do form hydrogen bonds with water.

Is oil a reasonable energy source? Why or why not? ​

Answers

Answer:

No, it is not.

Explanation:

Oil is a non-renewable source of energy. ... Burning oil can pollute the air. Much of our oil has to be imported and it is becoming more and more expensive as reserves reduce and imports increase. Producing electricity from crude oil is expensive compared to other fossil fuels such as coal or gas.

Calculate the percent ionization of a 0.381 M solution of hydrocyanic acid.

Answers

Answer:

.00402 %

Explanation:

hydrocyanic acid (HCN) is a weak acid with a Ka of 6.17*10^-10 so you need to do a RICE table

initial concentration of HCN is .381 and initial H+ and CN- concentration is 0.

that means the equillibrium concentration of HCN will be (.381-x) and H+ and CN- will be x

put that into the formula for Ka, so it'll be Ka = x^2/(.381-x) and then use quadratic equation to solve. You'll end up getting x = 1.5 * 10^-5.

Then to find percent ionization you solve (concentration of formed ions / initial HCN)

Which will be (1.5 * 10^-5 / .381) * 100 = .00402 % making it a very weak acid <3
