Identify the conjugate acid/base pairs in each of the following equations:

Chemistry
1 answer:
Valentin [98]3 years ago
6 0

Answer:

(a) Pair 1: H₂S and HS⁻

    Pair 2: NH₃ and NH₄⁺

(b) Pair 1: HSO₄⁻ and SO₄⁻

    Pair 2: NH₃ and NH₄⁺

(c) Pair 1: HBr and Br⁻

    Pair 2: CH₃O⁻ and CH₃OH

(d)  Pair 1: HNO₃ and NO₃⁻

     Pair 2: H₃O⁺

Explanation:

When an acid loses its proton (H⁺), a conjugate base is produced.

When a base accepts a proton (H⁺), it forms a conjugate acid.

(a) H₂S is an acid. When it loses a proton, it forms the conjugate base HS⁻.

    NH₃ is a base. When NH₃ gains a proton, it forms the conjugate acid NH₄⁺

(b) The acid HSO₄⁻ loses a H⁺ ion and forms the conjugate base SO₄²⁻.

     The base NH₃ accepts a H⁺ ion to form the conjugate acid NH₄⁺.

(c) HBr is an acid. When loses the H⁺ ion, it forms the conjugate base Br⁻.

   CH₃O⁻ accepts a H⁺ ion to form the conjugate acid CH₃OH.

(d) HNO₃ loses a proton to form the conjugate base NO₃⁻.

    H₂O gains a proton to form the conjugate acid H₃O⁺.

Answer:

$CF_3CO_2H> CHF_2CO_2H>CH_2FCO_2H>CH_3CO_2H$

Explanation:

Florine has the highest electronegativity and it thus pulls the element of $OH^- groups in the COOH group towards itself, making it relatively easy to loose the proton of the carboxyl group.

Boron has 5 protons. If another proton gets added to boron, what will happen?
Alla [95]

If another proton gets added to the molecule there will be an increase in the atomic number and atomic mass by 1 unit and a new species will form.

here boron is taken which has an atomic number of 5 and atomic mass of 11 so when we add  a proton to it, it will change into carbon having atomic number as 6 and atomic mass as 12.

_{5}^{11}\textrm{B}+_{1}^{1}\textrm{p}\rightarrow _{6}^{12}\textrm{C}

The new species formed will be _{6}^{12}\textrm{C}.
