The net ionic equation for formation of an aqueous solution of AI(NO3)3 via mixing solid Al(OH)3 and aqueous nitric acid is
A) Al(OH)3 (s) + 3HNO3 (aq) + 3H20 (1) + AI(NO3)3 (aq)

B) Al(OH)3 (s) + 3NO3- (aq)
3OH- (aq) + AI(NO3)3 (aq)

C) Al(OH)3 (s) + 3NO3- (aq) + 3OH- (aq) + AI(NO3)3 (s)

D) Al(OH)3 (s) + 3H+ (aq) + 3H20 (1) + A13+ (aq)

E) Al(OH)3 (s) + 3HNO3 (aq) + 3H20 (1) + A13+ (aq) + NO3- (aq)

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
