Correct answer: by a random, short-lived redistribution of electrons.
van der Waal's forces are the weak intermolecular forces of attraction or repulsions that are seen in all molecules, when they come close to each other. These forces of attraction or repulsion are due to the momentary charges that develop between the electron clouds of one atom and the nuclei of the other atom. Therefore, the van der Waal's forces are due to the instantaneous dipoles that are produced between two atoms close to each other, due to the redistribution of electron clouds.
Answer:
[OH-] = 1.0 x 10-10 M
Explanation:
The acidity of a solution can be determined directly from the concentration of the hydrogen ions and indirectly from the concentrations of the hydroxide ions.
Generally, for a neutral solution we have;
[H3O+] = [OH-] = 1.0 x 10-7 M
For an acidic solution;
[H3O+] > 1.0 x 10-7 M
[OH-] < 1.0 x 10-7 M
Comparing the options the correct option is;
[OH-] = 1.0 x 10-10 M
Answer:
It emits hydrogen sulfide...smells like rotten eggs..
ty:)pls let me know whether this is ryt:D
The term sensitivity in Analytical Chemistry is "the slope of the calibration curve or a function of analyte concentration or amount".
<u>Answer:</u> Option B
<u>Explanation:</u>
In a sample, the little amounts of substances can be accurately evaluated by a method is termed as "Analytical sensitivity". This detect a target analyte like an antibody or antigen, process is considered as potential of a test to and generally demonstrated as the analyte's minimum detectable concentration.
The acceptable diagnostic sensitivity is not guaranteed by high analytical sensitivity. The percentage of individuals who have a given disarray who are identified by the method as positive for the disarray is known as "Diagnostic sensitivity".
