Silicon
Silicon has the chemical properties that are most similar to those of carbon.
Answer:
% Mass of sand = 35.95%
% Mass of KBr = 64.05%
Explanation:
From the question given, we obtained the following:
Mass of mixture( KBr + sand) = 10g
Mass of sand = 3.595g
Mass of KBr = 10 — 3.595 = 6.405g
% Mass of sand = ( Mass of sand / mass of mixture) x 100
% Mass of sand = (3.595 / 10) x100
% Mass of sand = 35.95%
We can obtain the percentage of KBr by subtracting the percentage of sand from 100. This is illustrated below:
% Mass of KBr = 100 — 35.95
% Mass of KBr = 64.05%
Answer:
17.2 minutes is the value of the turnover number.
Explanation:
Using Michaelis-Menten equation:
![V = V_{max}\times \frac{[S]}{ (Km + [S])}](https://tex.z-dn.net/?f=V%20%3D%20V_%7Bmax%7D%5Ctimes%20%5Cfrac%7B%5BS%5D%7D%7B%20%28Km%20%2B%20%5BS%5D%29%7D)

Where :
= max rate velocity
[S] = substrate concentration
= Michaelis-Menten constant
V = reaction rate
= catalytic rate constant
= initial enzyme concentration
We have :


is the rate is obtained when all enzyme is bonded to the substrate.
is termed as the turnover number.


17.2 minutes is the value of the turnover number.
