39462 KJ of Gibbs free energy will produce. Number of moles of nitrogen = 90 moles, E0 = 0.74 + ( - 0.42) = 0.74 - 0.42 = 0.32
<h3>
What is a Balanced chemical equation?</h3>
A balanced chemical equation has the same number of reactants and products. We can balance a chemical equation by adding a number to adding the same number of molecules on both sides.
In this equation,
10NO3 + 10 e - -> 5N2
4H + 2 e - -> 2H2
In this equation, 5 moles of N2 and 2 moles of Hydrogen are produced.
5 * 0.74 = 3.7 V
2 * ( -0.42) = - 0.84 V
ΔG = -nFΔE,
where F = 96.48 kJ (mol e-)
= 90 * 96.48 * (3.7 + 0.84)
= 90* 96.48* 4.54
= 39462 KJ
Therefore, 39462 KJ of Gibbs free energy will produce. Number of moles of nitrogen = 90 moles, E0 = 0.74 + ( - 0.42) = 0.74 - 0.42 = 0.32.

Answer:
A conserved set of cyclin-dependent protein kinases (Cdks) initiate or regulate events through phosphorylation of intracellular proteins, thus controlling cell cycle progression, terminal differentiation, and apoptosis. ...
Explanation:
Yes it is.
Carbon dioxide goes through plants, which they turn into oxygen. Humans and animals take in the oxygen and breathe out carbon dioxide. Then it repeats.

Answer:
Energy is said to flow in a "one-way stream" through an ecosystem. In your own words, describe what that means. Energy is not recycled. Energy enters an ecosystem and flows through a food chain, but it is not reused, it is lost as heat.
Hope the answer helps:)
