If you complete and balance the following oxidation-reduction reaction in basic solutionno2−(aq) + al(s) → nh3(aq) + al(oh)4−(aq)how many hydroxide ions are there in the balanced equation (for the reaction balanced with the smallest whole-number coefficients)?

There is one 1 hydroxide ion in the balanced equation.

Explanation:

Oxidation reaction is defined as the chemical reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

For the given chemical reaction:

The half cell reactions for the above reaction follows:

Reduction half reaction:  

Oxidation half reaction:  

Multiplying the Oxidation half reaction by 2 and we get that:-

Adding the half reactions, we get that:-

There is one 1 hydroxide ion in the balanced equation.

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary
