The part of the carbon cycle where humans had the greatest impact is the return of CO₂ to the atmosphere by burning of ancient organic matter.
The ancient organic matter is also called Fossil Fuels. Some Fossil Fuels are Petroleum and Coal.

Of any substance? What about two powders such as 1/2 cup of white flour, then mixing 1/2 cup of salt together with the flour. This would then form a more coarse mixture being that the two particles differ in shape.
The balanced form of the chemical equation shown is N₂(g) + 3H₂(g) → 2NH3(g) (option A).
<h3>What is a balanced equation?</h3>
A chemical equation is said to be balanced when the number of atoms of each element on both sides of the equation is the same.
According to this question, the chemical equation between nitrogen and hydrogen is given as follows: N₂(g) + H₂(g) → NH3(g)
The balanced form of the chemical equation shown is N₂(g) + 3H₂(g) → 2NH3(g).
