Identify each substance as an acid or a base and write a chemical equation showing how it is an acid or a base according to the Arrhenius definition. (a) H2SO4(aq)

(b) Sr(OH)2(aq)

(c) HBr(aq)

(d) NaOH(aq)

(a) Acid

(b) Base

(c) Acid

(d) Base

Explanation:

According to the Arrhenius acid-base theory:

(a) H₂SO₄ is an acid according to the following equation:

H₂SO₄(aq) ⇒ 2 H⁺(aq) + SO₄²⁻(aq)

(b) Sr(OH)₂ is a base according to the following equation:

Sr(OH)₂(aq) ⇄ Sr²⁺(aq) + 2 OH⁻(aq)

(c) HBr is an acid according to the following equation:

HBr(aq) ⇒ H⁺(aq) + Br⁻(aq)

(d) NaOH is a base according to the following equation:

NaOH(aq) ⇒ Na⁺(aq) + OH⁻(aq)

the child will have heterozygous dominant chromosomes as characters of his father are dominant over the characters of his mother.

the child is heterozygous

it is stable as it is in group 0 which have full outer shells of electrons
