Options are;

(A) H-O bonds break as H-H and O-O bonds form.

(B) Hydrogen bonds between H2O molecules are broken.

(D) Ionic bonds between H+ ions and OH− ions are broken.

(E) Covalent bonds between H+ ions and H2O molecules become more effective.

Answer:

B: Hydrogen bonds between H2O molecules are broken.

Explanation:

When water is changing from liquid form to vapour form, it's molecules move at a faster rate. This is because the bonds between the molecules have been broken as a result of the heat that converts the liquid to vapour.

And the type of bond that forms water molecules is hydrogen bonds.

Thus, hydrogen bonds are broken when converting from liquid to vapour phase.

Atomic number is defined as the number of protons or number of electrons.

Atomic number = number of protons = number of electrons

Mass number is defined as the sum of number of protons and number of neutrons.

Number of neutrons = Mass number - Number of protons

Number of electrons = Number of protons - charge

Can the ratio of hydrogen to oxygen change if a solute is dissolved in the water

coldgirl [10]

Answer:

Water molecules feature the combinations of hydrogen and oxygen atoms in a 2:1 ratio. Since they are present in a fixed ratio of mass, water molecules obey the law of constant proportions. Water is formed when two molecules of the diatomic hydrogen gas, combine with one molecule of the diatomic oxygen gas to produce two molecules of water

The reaction is shown below,

Step 1: Hydration of Alkene:
In first step Ethene is hydrated to Ethanol through Hydroboration Reaction.

Step 2: Oxidation of Primary Alcohol:
In this step partial oxidation of ethanol is carried out using mild Oxidizing agent <span>Pyridinium chlorochromate (PCC) and Acetaldehyde is produced.

Step 3: Reduction of Acetaldehyde followed by Oxidation:
In this step, first acetaldehyde is reduced to secondary alcohol using grignard reagent. After that the sec. alcohol is oxidized to ketone by using oxidizing agent CrO</span>₃.
