During a spectrophotometric analysis of an unknown, you measure your solution's absorbance, and the value is higher than the hig
Reil [10]

Answer:

A) Dilute the unknown so that it will have an absorbance within the standard curve. Once the diluted unknown concentration is determined, the full strength concentration can be calculated if the dilution process is recorded. Beer's law only applies to dilute solutions, so diluting the unknown is better than making new standards.

Explanation:

Beer's law states that <em>absorbance is proportional to the concentrations of the absorbing species</em>. This is verified in the case of diluted solutions (0≤0.01 M) of most substances. <u>As a solution gets more concentrated, solute molecules interact between themselves because of their proximity. </u>When a molecule interacts with another, the change in their electric properties (including absorbance) is probable. That's why <u>the plot of absorbance versus concentration stops being a straight line</u>, and <u>Beer's law is no longer valid.</u>

Therefore, if the absorbance value is higher than the highest standard,  dilutions should be made. Once this concentration is determined, the full strength concentration can be calculated with the inverse of the dilution.

What is the product of the unbalanced equation below?
Stolb23 [73]

Answer:

D

Explanation:

The answer is D. I'm not sure that it is a solid. I don't think it is a ppte, which is the only way it can be a true solid. It is ionic if the reaction is taking place in water and there is someway to start the reaction. Be that as it may, the internal balace numbers of the chemical produced is the only possible answer. The balanced eq;uatioon is

2Al + 3Br2 ==> 2AlBr3

Outline the difference between compounds and mixtures. State two examples of each.
alekssr [168]

Compounds are elements and its a pure substance with a gised composition.

Mixtures two or more subtances mixed to together.There are 2 type of mixtures.

Homegenous Mixtures (Solutions)-Two or more substances mixed but is uniform, you cant see the different mixtures.

Ex:Sugar mixed with water.The sugar dissolves and becomes one with the water.

Heterogeneous Mixtures-Two or more substances mixed but is not uniformed.You can see all the substances put into the mixture.

Ex:A salad, you can see whats all mixed in the sald and can pick it apart.
