When water turns to steam,
D) the water absorbs energy which causes the water molecules to have more kinetic and potential energy changing their configuration from a liquid to a gas.

It’s really any metal because metals form metallic bonds. They are the only substances which can make metallic bonds. So the answer is A
Answer:

Explanation:
First of all we need to find the amount of atoms per volume (m³). We can do this using the density and the molar mass.

Now, the fraction of vacancies is equal to the N(v)/N ratio.
- N(v) is the number of vacancies

- N is the number of atoms per volume calculated above.
Therefore:
The fraction of vacancies at 600 °C will be:

Answer:
Nitrification is a biological process by which ammonia is oxidized to nitrites (
) and then to nitrates (
) by action of specialized bacteria in nature (such as <em>nitrosomonas</em> and <em>nitrobacter</em>).
Explanation:
This two-step process utilizes molecular atmospheric oxygen and ammonia and ammonium components of soil and nature.
<em>(a.) Ammonia and ammonium compounds to nitrite</em>
→ 
→ 
<em>(b.) Nitrite to nitrate</em>
→ 
<em>(c.) The reverse process involves reduction of nitrates to molecular nitrogen, called denitrification (with succinic acid in the equation below).</em>
→
(
and
is an intermediate product in this process.)
