Reaction
N₂ + 3H₂ → 2NH₃
1 mol = 6.02 x 10²³ particles
9.6 X 10²¹ molecules of Hydrogen, mol :
![\tt \dfrac{9.61\times 10^{21}}{6.02\times 10^{23}}=1.596\times 10^{-2}~moles](https://tex.z-dn.net/?f=%5Ctt%20%5Cdfrac%7B9.61%5Ctimes%2010%5E%7B21%7D%7D%7B6.02%5Ctimes%2010%5E%7B23%7D%7D%3D1.596%5Ctimes%2010%5E%7B-2%7D~moles)
mol H₂ : mol NH₃ = 3 : 2
mol NH₃ :
![\tt \dfrac{2}{3}\times 1.596\times 10^{-2}=0.0106](https://tex.z-dn.net/?f=%5Ctt%20%5Cdfrac%7B2%7D%7B3%7D%5Ctimes%201.596%5Ctimes%2010%5E%7B-2%7D%3D0.0106)
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). <em>At STP, Vm is 22.4 liters/mol.</em>
The volume of NH₃ :
![\tt 0.0106\times 22.4=0.237~L](https://tex.z-dn.net/?f=%5Ctt%200.0106%5Ctimes%2022.4%3D0.237~L)

The answer to the question would be the skin.
The answer: A
Explanation: fossil fuels need to be burned to release the energy stored in them, Which leads to smoke casting cans gas being pumped into the air. Unfortunately, burning fossil fuels Releases harmful particles and greenhouse gases into the atmosphere, resulting in adverse affects humans and earth as a whole.
Answer:
D. Phosphorylation by ATP, which turns the complex off, and dephosphorylation, which turns the complex on.
Explanation:
The pyruvate dehydrogenase complex (PDH) is responsible for the conversion of pyruvate to acetylCoA, the fuel for the citric acid cycle.
The regulation of the activity of PDH is allosterically by the products of the reaction which it catalyses. These products are ATP, acetylCoA and NADH. When their is sufficient fuel available for the needs of the cells in the form of ATP, the complex is turned off by phosphorylation of one of the two subunits of E1 (pyruvate dehydrogenase). This phosphorylation inactivates E1. When the concentration of ATP declines, a specific phosphatase removes the phosphoryl group from E1, thereby activating the complex again.
