the poly atomic molecule is H2
The best answer choices can be A.because it reduction he eletrolytic from positive
Answer:
300 mM
Explanation:
In order to solve this problem we need to calculate the line of best fit for those experimental values. The absorbance values go in the Y-axis while the concentration goes in the X-axis. We can calculate the linear fit using Microsoft Excel using the LINEST function (alternatively you can write the Y data in one column and X data in another one, then use that data to create a dispersion graph and finally add the line of best fit and its formula).
The <u>formula for the line of best fit for this set of data is</u>:
So now we <u>calculate the value of </u><u><em>x</em></u><u> when </u><u><em>y</em></u><u> is 1.50</u>:
Valence electrons are located in the outermost shell of the atom.
Answer:
The answer to your question is: D. Fractional distillation
Explanation:
A. Column chromatography this method is use to separate mixtures base in its capacity to be absorbed.
B. Fractional crystallization this method use the solubility of solutes in a solvent.
C. Simple distillation is a method to separate 2 liquids based on the difference in their boiling points.
D. Fractional distillation is a method used to separate a mixture of liquids which have their boiling points very close.
E. Paper chromatography is a method to separate a mixture based on their different rate of migration on a paper.
