Complete the reaction equations in molecular, ionic and abbreviated ionic form 1) aluminum hydroxide + nitric acid 2) magnesium chloride + silver nitrate

a) Al (OH) 3 + 3HNO3 = Al (NO3) 3 + 3H2O, – on the basis of the compiled molecular equation of the ongoing reaction, we compose the ionic one. To do this, you need to paint dissociating (soluble) substances into ions:

Al (OH) 3 + 3H⁺ + 3NO3⁻ = Al³⁺ + 3NO3⁻ + 3H2O, – we got the complete ionic equation. To reduce it to an abbreviated form, it is necessary to mutually annihilate the same groups of ions in both sides of the equation:

Al (OH) 3 + 3H⁺ = Al³⁺ + 3H2O, – the abbreviated ionic equation is ready.

b) MgCl2 + 2AgNO3 = 2AgCl + Mg (NO3) 2, – on the basis of the compiled molecular equation of the ongoing reaction, we compose the ionic one. To do this, you need to paint dissociating (soluble) substances into ions:

Mg²⁺ + 2Cl⁻ + 2Ag⁺ + 2NO3⁻ = 2AgCl + Mg²⁺ + 2NO3⁻, – we got the complete ionic equation. To reduce it to an abbreviated form, it is necessary to mutually annihilate the same groups of ions in both sides of the equation:

2Cl⁻ + 2Ag⁺ = 2AgCl, – the abbreviated ionic equation is ready.
