Answer:
7.4.
Explanation:
∵ pH = -log[H₃O⁺].
∴ pH = -log(2.5 x 10⁻⁷) = 6.6.
<em>∵ pH + pOH = 14.</em>
<em />
∴ pOH = 14.0 - pH = 14.0 - 6.6 = 7.4.
B. not fully absorbed by the atmosphere.
Explanation:
Visible light, which has a wavelength of between 380nm and 760nm is usually not fully absorbed by the atmosphere.
The earth's atmosphere is transparent to visible light emanating from the sun.
When visible light is radiated out from the sun, on reaching the atmospheric cover of the earth, it goes through without restraints.
- Little to no interaction occurs between the atmospheric cover of earth and visible light.
- This is why the surface is bright and receives sunlight.
- Other more energetic radiations interacts with atmosphere.
- Some of them gets cut off and some partially penetrate through.

Answer: A. An element with the valence electron configuration 5s1 would form a monatomic ion with a charge of Answer: +1. In order to form this ion, the element will Answer: lose electron(s) from/into the 5s subshell(s).
Explanation:
Answer:
Blood is liquid and red, just like a red river. And for humans without blood there is no life because there is nothing to transport nutrients and oxygen to the body cells. Hence blood is the red river of life.
Explanation:
The given reaction is as follows.
![E + S \rightleftharpoons ES \xrightarrow[]{k_{2}} E + P](https://tex.z-dn.net/?f=E%20%2B%20S%20%5Crightleftharpoons%20ES%20%5Cxrightarrow%5B%5D%7Bk_%7B2%7D%7D%20E%20%2B%20P)
Here, [E] = triose phosphate isomerase = 0.1 
[S] = Dihydroxy acetone phosphate = 5 
[P] = Glyceraldehyde-3-phosphate = 2 
Therefore, velocity of the reaction will be as follows.
v = ![\frac{d[P]}{dt}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5BP%5D%7D%7Bdt%7D)
= ![\frac{K_{2}[E][S]}{K_{M} + [S]}](https://tex.z-dn.net/?f=%5Cfrac%7BK_%7B2%7D%5BE%5D%5BS%5D%7D%7BK_%7BM%7D%20%2B%20%5BS%5D%7D)
where, 
= Michaelic menten constant = 
v = 
= 
or, = 30 nm/s
Hence, we can conclude that the actual velocity of the forward reaction under physiologic conditions if KM = 10 μM is 30 nm/s.
