I’m not sure if you were looking for a definition or examples so I’ll give you both.

Definition: a conjugate acid is a chemical compound formed by the reception of a proton by a base. You could say it is a base with a hydrogen ion added to it. Also, a conjugate vase is what is left over after an acid has donated a proton during any chemical reaction.

Examples:

Sulfuric Acid (H2SO4) is an acid because it donates H+ to the water. It becomes the hydrogen sulfate ion (HSO-4) which is the conjugate vase if sulfuric acid.

Ammonia (NH3) is a base because it accepts H+ from water to come it’s conjugate acid, the ammonium ion (NH+4)

Answer:

A conjugate acid formed by accepting proton (H+) by a base—in other words, it is a base with a hydrogen ion added to it. On the other hand, a conjugate base is what is left over after an acid has donated a proton during a chemical reaction. Hence, a conjugate base is a species formed by the removal of a proton from an acid.

Verdich [7]
 <span>% by mass = mass solute x 100 / mass solution 

45.5 % = mass solute NaF x 100 / 34.2 

mass solute NaF = 34.2 x 45.5 /100=15.6 g 

molae solute NaF = 15.6 g ( 1 mol / 41.9887 g)= 0.372</span>

What are the similarities and differences between ionic and covalent bonds?
ohaa [14]

Answer:

Explanation:

Similarities.

Both Ionic and covalents bond produce exothermic reactions.

They are both neutral.in Ionic bonds, the two opposite charge will terminate each other and in covalent, the neutral molecules tend to share electrons.

Difference

Ionic bonds have high polarity while covalent have low.

Ionic bonds have no definite shape, covalent have.

Ionic have high melting points, covalent have low.

Io ic have high boiling point, covalents have low.
