Answer #1

Arsenic has 5 valence electrons.

Thus, it requires 3 more electrons for octet configuration.

Hence, it is expected to form 3 covalent bonds.

-

Arsenic needs 3 covalent bonds with 3 hydrogen atoms to satisfy octet rule.

Hence, the formula of the compound that would form between As and H = AsH3

-

NH4Cl(aq) ------> NH4+(aq) + Cl-(aq)

Ammonium chloride gives ammonium cation and chloride anion on complete dissociation in water.

-

CH3COONa(aq) ------> Na+(aq) + CH3COO-(aq)

Sodium acetate gives sodium cation and acetate anion on complete dissociation in water.
