Each mole of nitrogen that microbes fix requires the breakdown of 16 moles of ATP (adenosine triphosphate). The energy needed by these microbes is obtained by oxidizing organic compounds. In other words, the nitrogenase enzyme must use a significant amount of energy to convert N2 to NH3.
The great majority of nitrogen on Earth exists as molecular N2, and before to the agricultural and industrial revolutions, the only significant mechanism producing reactive nitrogen was biological nitrogen fixation. Any natural or artificial process known as nitrogen fixation causes free nitrogen (N2), a relatively inert gas present in large quantities in the atmosphere, to chemically interact with other elements to generate more reactive nitrogen compounds like ammonia, nitrates, or nitrites. carbon cycle.

<span>Just solve this by using the molar mass/molecular weight, and the avogadros number in a dimensional analysis
18.46 g Cu x (1 mole/64 g) x (6.022 x 10^23 atoms/1 mole) = 1.74 x 10^23 atoms
</span><span>67.69 g NaCl x (1 mole/58 g) x (6.022 x 10^23 formula units/ 1 mole) = 7.03 x 10^23 formula units
</span>44.99 g H2O x (1 mole/18 g) x (6.022 x 10^23 molecules/ 1 mole) = 1.51 x 10^24 molecules
<span>0.250 moles Mg x (24 g/1 mole) = 6 g

Since the entomb sub-atomic powers must be totally broken overcome to end up a gas. The powers essentially should be relaxed when softening happens.
2nd one, the molecules of the food in the oven are moving faster than the molecules of the food in the freezer.
Even if the food is frozen, the molecules are still moving because they have energy, but when the food is hot, the molecules move even faster.
Answer:
It will lose 2 electrons
Explanation:
Here we have a calcium atom, which has 20 electrons.
Those 20 electrons are in 4 shells. (2-8-8-2)
Saying there are 2 electrons in the valence shell (Shell N), to get to an octet with an ionic bond (with a group 16 element), those 2 electrons will have to go.
