Answer: to calculate pH use -log[H+] or - log[OH-]..the solution is basic as the “NaOH” is attached to a hydroxide.Since we need to find the pH (per hydrogen) and not the pOH( per hydroxide) we need to find the pOH of the substance first then we subtract that by 14 so we can arrive at the pH of the substance.
Explanation: So -log( 1 x 10^(-5)) = 5 which is the pOH.Now we subtract that by 14 which gives us -9 and now you’d multiply that by -1 bcuz we can’t have a negative so the pH of the substance is 9
Hello!
the atomic mass of one atom of hydrogen is equal to 1.00784 in atomic mass units
one atomic mass unit is equal to 3.6609e-27 pounds
which means one atom of hydrogen is equal to 3.9478732e-27 pounds
I hope this helps, and have a nice day!
Answer:
The value of the Michaelis–Menten constant is 0.0111 mM.
Explanation:
Michaelis–Menten 's equation:
![v_o=V_{max}\times \frac{[S]}{(K_m+[S])}=k_{cat}[E_o]\times \frac{[S]}{(K_m+[S])}](https://tex.z-dn.net/?f=v_o%3DV_%7Bmax%7D%5Ctimes%20%5Cfrac%7B%5BS%5D%7D%7B%28K_m%2B%5BS%5D%29%7D%3Dk_%7Bcat%7D%5BE_o%5D%5Ctimes%20%5Cfrac%7B%5BS%5D%7D%7B%28K_m%2B%5BS%5D%29%7D)
![V_{max}=k_{cat}[E_o]](https://tex.z-dn.net/?f=V_%7Bmax%7D%3Dk_%7Bcat%7D%5BE_o%5D)
Where:
= rate of formation of products
[S] = Concatenation of substrate
![[K_m]](https://tex.z-dn.net/?f=%5BK_m%5D)
= Michaelis constant
= Maximum rate achieved
= Catalytic rate of the system
![[E_o]](https://tex.z-dn.net/?f=%5BE_o%5D)
= Initial concentration of enzyme
On substituting all the given values
We have :
[S] = 0.10 mM
![\frac{v_o}{V_{max}}=\frac{[S]}{(K_m+[S])}](https://tex.z-dn.net/?f=%5Cfrac%7Bv_o%7D%7BV_%7Bmax%7D%7D%3D%5Cfrac%7B%5BS%5D%7D%7B%28K_m%2B%5BS%5D%29%7D)
The value of the Michaelis–Menten constant is 0.0111 mM.
Answer:
Divers breathe compressed air that contains nitrogen. At higher pressure under water, the nitrogen gas goes into the body's tissues. ... Nitrogen narcosis: Deep dives can cause so much nitrogen to build up in the brain that you can become confused and act as though you've been drinking alcohol.Oxygen becomes rapidly toxic at depth – prolonged exposure to pure oxygen below a few metres can kill you. It is not an appropriate scuba tank gas mixture. ... Oxygen is also highly reactive and can make other substances flammable. Safety training is necessary to work with pure oxygen.
Explanation:
I hope this helped,i m sorry if its not the exact answer you need.
The first step to solve this problem is to multiply the volume of solution times its concentration to find the number of moles needed, remember that M=mol/L:
Now, use the molar mass of sucrose to find the number of grams needed to make the solution. This is, multiply the number of moles needed times the molar mass:
It means that to make 0.500L of a 0.475M you will have to weigh 81.225g of sucrose.
