What does a concentration gradient do to etc?

1 answer:

5 0

<span>Concentration of a chemical in a solution refers to how many of the chemical's molecules are sitting in a small volume of the solution. Concentration could be measured in molecules per liter, although molecules are so small compared to a liter that we usually use different units (just like we wouldn't want to measure the distance between the earth and the sun in inches). A gradient is a measurement of how much something changes as you move from one region to another. So a concentration gradient is a measurement of how the concentration of something changes from one place to another.

Consider two different solutions of the same UV-absorbing compound. Upon UV-analysis, Solution B gave an absorbance of 1.0 and S

Juliette [100K]

We have that the Concentration of solution B is 2.5 times more than solution A's concentration.

<h3>UV(Ultra violent) rays</h3>

Question Parameters:

Upon UV-analysis, Solution B gave an absorbance of 1.0

Solution A gave an absorbance of 0. 4

Generally the equation for the Absorbance is mathematically given as

A = e*c*L

Therefore

For A solution

$0.4 = e*[cA]*L$

For B solution

$1.0 = e*[cB]*L$

Hence

$\frac{0.4}{ 1} = \frac{[cA]}{ cB}$

[cB] = 2.5 [cA]

Therefore

Concentration of solution B is 2.5 times more than solution A's concentration.

Which is the most accurate description of compounds?

baherus [9]

Answer: c.They have a unique set of properties that can be used as identifiers.

Explanation:

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.

Compounds can be decomposed into simpler constituents using chemical reactions.

Example: Water $(H_2O)$
