Answer 1

Answer:

Cd(NO₃)₂ + 2NH₄Cl → CdCl₂ + 2NH₄NO₃

Explanation:

The reaction given is a double replacement reaction, which means that the reactants will dissociate and the ions will be changed between them. So, let's identify the ions.

At Cd(NO₃)₂, the metal Cd has cation Cd⁺², and the anion is NO₃⁻ (the number of ions is changed and the cation is the first to appear in the formula). At NH₄Cl, the cation is NH₄⁺ and the anion is Cl⁻, so the products are CdCl₂ and NH₄NO₃ (the cation comes first, and the charges are replaced between them).

So, the reacion will be:

Cd(NO₃)₂ + NH₄Cl → CdCl₂ + NH₄NO₃

To balance the equation, all the elements must have the same number on both sides, thus we need to multiply NH₄Cl and NH₄NO₃ by 2:

Cd(NO₃)₂ + 2NH₄Cl → CdCl₂ + 2NH₄NO₃

Answer 2

CdCl2+2NH4NO3

It is substitution reaction

Cd is metal with 2+ which connect with Cl(-)

NO3 with NH4 form salt
