Answer 2

Molecular Equation:

The molecular equation for the reaction between potassium hydroxide (KOH) and nitric acid (HNO3) is:

KOH + HNO3 → KNO3 + H2O [[1]]

Ionic Equation:

To write the ionic equation, we need to break down the reactants and products into their respective ions. Potassium hydroxide dissociates into potassium ions (K+) and hydroxide ions (OH-), while nitric acid dissociates into hydrogen ions (H+) and nitrate ions (NO3-). The reaction can be represented as follows:

K+ (aq) + OH- (aq) + H+ (aq) + NO3- (aq) → K+ (aq) + NO3- (aq) + H2O (l) [[1]]

Net Ionic Equation:

The net ionic equation is obtained by removing the spectator ions, which are ions that appear on both sides of the equation and do not participate in the reaction. In this case, the potassium ions (K+) and nitrate ions (NO3-) are spectator ions. The net ionic equation is:

OH- (aq) + H+ (aq) → H2O (l) [[1]]

Molecular Equation:

The molecular equation for the reaction between hydrogen bromide (HBr) and ammonia (NH3) is:

HBr + NH3 → NH4Br [[2]]

Ionic Equation:

To write the ionic equation, we need to break down the reactants and products into their respective ions. Hydrogen bromide dissociates into hydrogen ions (H+) and bromide ions (Br-), while ammonia does not dissociate in water. The reaction can be represented as follows:

H+ (aq) + Br- (aq) + NH3 (aq) → NH4+ (aq) + Br- (aq) [[2]]

Net Ionic Equation:

The net ionic equation is obtained by removing the spectator ions, which are ions that appear on both sides of the equation and do not participate in the reaction. In this case, the bromide ions (Br-) are spectator ions. The net ionic equation is:

H+ (aq) + NH3 (aq) → NH4+ (aq) [[2]]

Please note that the above equations are simplified representations of the reactions and may not account for all the possible species present in the solution.
