Answer:

                     Answers are in the examples of Conjugate Base.

Explanation:

                    Conjugate Acid is a specie which is formed when a base abstract or picks a proton (H⁺).

Example:

               NH₃  +  HCl   →  NH₄⁺  +  Cl⁻

In this example Ammonia (NH₃) is a base which after reacting with acid forms the conjugate acid (NH₄⁺).

                    Conjugate Base is a specie which is formed when an acid looses / donates its proton (H⁺) to a base.

Example:

(a)

               B  +  HNO₃   →  BH⁺  +  NO₃⁻

In this example HNO₃ (Nitric Acid) is the acid which on reaction with base forms the conjugate base ( NO₃⁻) called nitrate.

(b)

               B  +  H₂SO₄   →  BH⁺  +  HSO₄⁻

               B  +  HSO₄⁻   →   BH⁺  +  SO₄⁻

In this example H₂SO₄ (Sulfuric Acid) is the acid which on reaction with base forms the conjugate bases ( HSO₄⁻ and SO₄⁻) respectively.

(c)

               B  +  H₂S   →  BH⁺  +  HS⁻

In this example H₂S (Hydrogen Sulfide) is the acid which on reaction with base forms the conjugate base HS⁻.

(c)

               B  +  HCOOH   →  BH⁺  +  HCOO⁻

In this example HCOOH (Formic Acid) is the acid which on reaction with base forms the conjugate base HCOO⁻ called formate ion.

Which of these charges has the greatest magnitude
Natalka [10]

Answer:

magnitude means absolute value, so the one that is greastest, like |-7| and |4| even id |-7| is a negative number, but it is still the one farthest away from 0, so |-7| is greater than |4|.

That is the way to find the greatest magnitude, but because I don't know your numbers so I can not answer your question, but this is the way to solve for it.

Identify the compound with the smallest dipole moment in the gas phase. identify the compound with the smallest dipole moment in
stepladder [879]
Without solving for the dipole moment, we can easily determine which among the common gases has the smallest dipole moment just by determining the differences in their electronegativity. The greater the difference in the electronegativity, the higher is the value of the dipole moment. 

From the given above, there are obvious differences between the electronegativity between the atoms composing LiF, ClF, and HF. For Cl2, since this is the same molecule then, the difference in the electronegativity is zero.

Answer: Cl2.
