Peter Parker is 28 years old in the 616 Marvel Universe. This answer is subject to change, as writers may adapt the age through their stories. Peter's age is somewhat fluid, aging in real time at some points, while almost not aging at all for some periods.
Answer:
The number of active sites enzyme have is 1.
Explanation:
Mass of penicillinase = 4.10 μg =![4.10\times 10^{-6} g](https://tex.z-dn.net/?f=4.10%5Ctimes%2010%5E%7B-6%7D%20g)
1 g = 1000000 μg
The turnover number of the enzyme at 28 °C = ![2.00\times 10^3 s^{-1}](https://tex.z-dn.net/?f=2.00%5Ctimes%2010%5E3%20s%5E%7B-1%7D)
Moles of penicillinase =
![\frac{4.10\times 10^{-6} g}{31200 g/mol}=1.31410\times 10^{-10} mol](https://tex.z-dn.net/?f=%5Cfrac%7B4.10%5Ctimes%2010%5E%7B-6%7D%20g%7D%7B31200%20g%2Fmol%7D%3D1.31410%5Ctimes%2010%5E%7B-10%7D%20mol)
Mass of antiboitic-amoxicillin =2.83 mg =![2.83\times 10^{-3} g](https://tex.z-dn.net/?f=2.83%5Ctimes%2010%5E%7B-3%7D%20g)
Moles of amoxicillin =
![\frac{2.83\times 10^{-3} g}{364 g/mol}=7.7747\times 10^{-6} mol](https://tex.z-dn.net/?f=%5Cfrac%7B2.83%5Ctimes%2010%5E%7B-3%7D%20g%7D%7B364%20g%2Fmol%7D%3D7.7747%5Ctimes%2010%5E%7B-6%7D%20mol)
Moles of reactant which are converted into product per second:
![1.31410\times 10^{-10} mol\times 2.00\times 10^3 s^{-1}](https://tex.z-dn.net/?f=1.31410%5Ctimes%2010%5E%7B-10%7D%20mol%5Ctimes%202.00%5Ctimes%2010%5E3%20s%5E%7B-1%7D)
=![2.6282\times 10^{-7} mol/s](https://tex.z-dn.net/?f=2.6282%5Ctimes%2010%5E%7B-7%7D%20mol%2Fs)
Moles of product converted in 29.6 seconds:
![2.6282\times 10^{-7} mol/s\times 29.6 s=7.779472\times 10^{-6} mol](https://tex.z-dn.net/?f=2.6282%5Ctimes%2010%5E%7B-7%7D%20mol%2Fs%5Ctimes%2029.6%20s%3D7.779472%5Ctimes%2010%5E%7B-6%7D%20mol)
Number of sites:
![=\frac{\text{moles of product}}{\text{moles of reactant}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5Ctext%7Bmoles%20of%20product%7D%7D%7B%5Ctext%7Bmoles%20of%20reactant%7D%7D)
![=\frac{7.779472\times 10^{-6} mol}{7.7747\times 10^{-6} mol}=1.00](https://tex.z-dn.net/?f=%3D%5Cfrac%7B7.779472%5Ctimes%2010%5E%7B-6%7D%20mol%7D%7B7.7747%5Ctimes%2010%5E%7B-6%7D%20mol%7D%3D1.00)
Answer:
a. eletrophile
b. able to impose regioselectivity and stereo selectivity.
c. faster
Explanation:
Necleophile reaction is chemical reaction in which electron rich chemical specie replaces functional group with another electron deficient molecule. Lewis acid catalyst is organic chemical reaction which lewis acid act as electron pair acceptor. Nucleophile reaction proceeds about 25 times more faster than benzene.
It could both the 2nd and the 3rd,
because if you add the exponents (2 + 1 + 6 = 9) you don't get 10.
and also each orbital level can and has to carry 2 electrons, and the 2s only has 1 there.
