The number of protons never changes in an atom. More electrons means a negative charge and fewer means a positive charge. Once an atom has an electrical charge it is called an ion. In an ion the atomic number and atomic mass do not change from the original.

What does molarity tell us that percent solution information does not tell us?
LUCKY_DIMON [66]

Answer:

Molarity tell us about the concentration of moles of solute in a solution.

Explanation:

Chemical substances are measured in terms of mole. Mole is defined as the amount of substance which contains 6.022×10²³ particles, ions or atoms. In System of international, amount of substance is measured in moles. So molarity tells us more information about amount of solute in a solution as compared to percent solution.

Treatment of an alpha,beta-unsaturated ketone with basic aqueous hydrogen peroxide yields an epoxy ketone. the reaction is speci
Misha Larkins [42]
The reaction mechanism for an alpha,beta-unsaturated ketone to react with basic peroxide to form an epoxide is shown below with a general ketone. The basic hydroxide is used to deprotonate the peroxide molecule to create a strong HOO- nucleophile. The peroxide then attacks the beta-carbon of the alkene and this pushes the electrons up to the oxygen of the carbonyl. This is the first intermediate that is formed during this reaction.

After the intermediate is formed, the lone pair from the oxygen pushes back down to form the carbonyl once more and this breaks a carbon-carbon bond which attacks the oxygen of the peroxy group, ultimately substituting an -OH group and forming the final epoxide ketone product.
