Some scientists hypothesize that Earth's ozone layer is being damaged by halogenated ozone depleting substances (ODS) such as chlorofluorocarbons (CFCs). CFCs have been known to damage the ozone layer for quite some time now which is why many products containing CFCs have been banned or discontinued (styrofoams, refrigerants, aerosols, etc)

An ionic bond is a bond between ____.

exis [7]

An ionic bond is a bond which occurs when there is a difference in the electronegativity of the atoms. One atom which has a stronger electronegativity tends to steal the electron of the other less electronegative atom hence making it more negative (anion), while the other becomes a cation. So answer is:

b. a cation and an anion

“Water” is the best thermal insulator.

Option: B

Explanation:

“Thermal insulators” are the materials which do not allow heat to transfer. “Water” is the substance which does not transfer heat. Hence, the “water” is the best “thermal insulator”. Water is the bad conductor of thermal heat. Water has “low thermal conductivity” than other substances, so this acts as an insulator as long as it is not traveled from one place to another. Heat is transferred when a “hot object collides” with “the cold objects”. The “thermal conductivity” of “water” is 0.6 W/m K.

choose any bases that will selectively deprotonate the above acid, that is, any bases that will favor the formation of products.

Zanzabum

In order to deprotonate an acid, we must remove protons in order to achieve a more stable conjugate base. For this example, we can use the relationship between carboxylic acid and hydroxide.

Deprotonation is the removal of a proton from a specific type of acid in reaction to its coming into contact with a strong base. The compound formed from this reaction is known as the conjugate base of that acid. The opposite process is also possible and is when a proton is added to a special kind of base. This is a process referred to as protonation, which forms the conjugate acid of that base.

For the example we have chosen to give, the conjugate base is the carboxylate salt. This would be the compound formed by the deprotonated carboxylic acid. The base in question was strong enough to deprotonate the acid due to the greater stability offered as a conjugated base.
