When a biomass is decaying, decomposers are eating these and use it as their food. As a byproduct from these organisms, they release nitrogen to the earth in the form of nitrates or nitrates increasing the amount of nitrogen present in the Earth. Hope this helps.
Carbon always has six protons, as its atomic number is six. Carbon twelve would have six neutrons (six protons plus six neutrons) in the nucleus of the atom. So the atomic number is 12
Answer:
(d) All spontaneous reactions have a negative free-energy change
Explanation:
All spontaneous reactions releases free energy which can be used later for the work to be done. A reaction with a negative value for ΔG releases free energy and is thus spontaneous
Answer:
Basic
Explanation:
The pH scale is measured from 0 to 14.
At the pH scale of 7, a solution is neutral.
Any solution above 7 is basic.
Any solution below 7 is acidic.
Because you have been given the hydronium concentration [H₃O⁺], you can find the pH of the solution using the following formula:
pH = -log[H₃O⁺]
pH = -log(6.0 x 10⁻¹²)
pH = 11.22
As you can see, the solution must be basic because the pH lies within the basic range.
