The luster tells if a mineral is metallic or not.
Answer:
10.7
Explanation:
According to this question, we have 4.60 × 10^-4 M hydroxide ion (OH-) concentration.
Since we were given the OH concentration, we first calculate the pOH of the solution, which is given as:
pOH = -log {OH-}
pOH = - log {4.60 × 10^-4}
pOH = - log {0.000460}
pOH = 3.337
pOH = 3.34
Given that; pOH + pH = 14
The pH of the solution = 14 - pOH
pH = 14 - 3.34
pH = 10.66
pH = 10.7
Answer:
Photosynthesis adds carbon dioxide to the air
Explanation:
Answer:
Explanation:
Blue-white screening is a method for distinguishing proof of (recombinant bacteria). It depends on the capacity of ( B-galactosidase) to separate lactose. Blue-white tests exploit the molecule called (x-gel)_ which is like lactose in that it is severed by B-galactosidase. When separated, the (5-bromo-4-chloro-indoxyl) (same as past) turns _(_blue). In the event that uncleaved, which implies a non-function B-gal gene, the X-gal remains (white)_. Subsequently, a __(white) bacterial province implies the B-galactosidase gene isn't practical, and in this way there ___lacz__ a recombinant gene embedded into the vector.
