D because n=1 is 1 and n so n equaling 1 makes sense becaude they requisite 1
It takes place in little or no oxygen.
The substance that can act as an Arrhenius base in aqueous solution is sodium hydroxide since NaOH dissociates in water giving the sodium ions and the hydroxide ions. An Arrhenius base is a substance that is characterized by forming hydroxide ions in an aqueous solution.
Explanation:
An equation that consists of same number of atoms on both reactant and product side is known as a balanced chemical equation.
For example, 
Number of atoms on reactant side are as follows.
C = 7
H = 6
O = 3
Number of atoms on product side are as follows.
C = 1
H = 2
O = 3
Therefore, to balance this chemical equation we multiply
by 8 on reactant side. Whereas we multiply
by 7 and
by 3 on product side.
Therefore, the balanced chemical equation will be as follows.
