Answer:
3 moles of hydrogen,
, are needed to react completely with 1 moles of nitrogen, ![H_2](https://tex.z-dn.net/?f=H_2)
Explanation:
Let us consider the Reaction of Nitrogen and hydrogen
![N_2 + 3H_2 \rightarrow 2NH_3](https://tex.z-dn.net/?f=N_2%20%2B%203H_2%20%5Crightarrow%202NH_3)
Two nitrogen atom reacts with 3 hydrogen atom to form ammonia. So it is clear from the chemical equation that 3 moles of hydrogen atom is essential to react completely with nitrogen.
Also when we see the atomic structure of hydrogen and nitrogen ,Hydrogen has only one electron its shell and nitrogen has 5 electron in its valency shell. so for an Nitrogen to have a completely filled shell, it needs 3 more electrons .Thus is need 3 hydrogen atom
Answer:
The salt will be located in period 6 of the periodic table.
Explanation:
Answer:
Fermentation
Explanation:
If your body were to break down glucose with the use of oxygen then it would be aerobic, but since oxygen isn't being used in this case, the process would be anaerobic or fermentation.
Hope this helps :)
I suck at explaining biology questions, but I tried.
Answer:
ΔH > O and ΔH > TΔS
Explanation:
When a reaction is non-spontaneous even though the standard entropy change of the reaction is large and positive the reason is the reaction is highly endothermic and dominates the term TΔS in the standard Gibbs free energy expression:
ΔG = ΔH-TΔS
Remember that for an endothermic reaction to be spontaneous ΔG < 0 and this can occur only if the term TΔS is greater than ΔH. This is not the case for quartz which requires a good quantity of energy to overcome its crystaline 3D lattice in which the oxygen are shared between 2 silicon atoms.
