Answer: Nitrogen Cycle

Explanation:

The nitrogen cycle is one of the most important biogeochemical cycle. It is an essential gas present in the atmosphere.

It is vital for the growth of plants and animals. Animals derive this nutrient by eating plants. But plants cannot take it in the form of nitrogen gas it takes it in different forms.

This is because the nitrogen fixing bacteria fixes nitrogen which means it converts nitrogen in the form which can be used by the plants.

So, the correct answer is nitrogen cycle as it needs to be modified before being used by plants.

What is the volume of a 5.30g piece of aluminum? The density for aluminum is 2.70gmL.
Blizzard [7]

The volume of the piece of aluminum is 1.96 mL

Explanation:

Density is the relationship of the mass of a substance and its volume.

In this case, the mass of aluminum is 5.30 g and the density is 2.70 g/mL

The formula to apply is;

D=M/V where D is density in g/mL, M is mass in g and V is volume in mL

2.70=5.30/V

V=5.30/2.70 =1.96 mL

What volume of a 1.0 M HCl is required to completely neutralize 25.0 ml of a 1.0 M KOH?
kirza4 [7]
The question above can be solved by using this equation: 
CAVA =CBVB
Where:
CA =Concentration of acid = 1.0 M
VA = Volume of acid = ?
CB = Concentration of base = 1.0 M
VB = Volume of base = 25 ml
VA = CBVB / CA
VA = [1 * 25] / 1 = 25 / 1 = 25
VA = 25 ml
Therefore, the volume of acid that is required to completely neutralize the base is 25 ml.<span />
