Quick! you mix two liquids together, and they begin to bubble. has a chemical reaction occurred? why or why not? ( explain to the best of your ability in your own words and not copy off other websites or other answers, ) : )

Yes a chemical reaction has occurred, because it fizzled, ad probably gave off energy as a result of the reaction

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
