The law that states that the volume of a gas is proportional to the moles of the gas when pressure and temperature are kept constant is Avogadro’s law. That is option D.
<h3>What is Avogadro’s law?</h3>
Avogadro’s law states that the volume of a gas is proportional to the moles of the gas when pressure and temperature are kept constant.
Mathematically the Avogadro’s law can be represented by the following:
V1/n1= V2/n1
Where,
V1 = first volume
n1 = first amount of gas
V2 = second volume
n2 = second amount of gas

Answer:
N₂(g) + 4H⁺(aq) + 4e⁻ → N₂H₄(aq)
Explanation:
The half reaction for the reaction for the reduction of gaseous nitrogen to aqueous hydrazine is;
N₂(g) → N₂H₄(aq)
The balancing the atoms in the half reaction. Hydrogen atom is balanced by adding hydrogen ions (H⁺)
We have;
N₂(g) + 4H⁺(aq) → N₂H₄(aq)
Then we balance the charge on both sides by adding electrons where the positive charge is greater;
we have;
N₂(g) + 4H⁺(aq) + 4e⁻ → N₂H₄(aq)
It is to create energy that the cell can use. it takes in oxygen to break down food molecules to get cellular energy for cell function
Water is a very good solvent due to its very polar nature. A polar substance is one where the atoms within the molecules of the substance carry partial charges. Oxygen is very electronegative, so it induces partial charges within the bonds of the water molecule. The extremely polar nature of water, along with its ability to make hydrogen bonds, ensure that it is able to dissolve a variety of substances.
A compound is a substance formed when two or more chemical elements are chemically bonded together
