In this experiment, a calibration curve, often called a Beer's Law plot, will be made. A calibration curve should have which of
mr_godi [17]

Answer:

B, C  and F are true, see explanation below.

Explanation:

Beer´s law is given by the formula:

A = εcl,  where   A = Absorbance,

                           ε = molar extinction coefficient,

                           c = concentration in mol/L (M), and

                           l = path length of the cuvette containing the sample,

                               

Now the usefulness of this relation is that if we plot the Absorbance vs  concentration, we get a straight line since the Beer equation has the form  y = mx + b.After the slope and y intercept have been determined, we can determine an unknow concentration of the substance by measuring its absorbance.

This relation is valid for low concentration, and  there are deviations from it.

We are now ready to answer this question with this brief introduction:

A. Absorbance is plotted on the x-axis

False, we plot the absorbance in the y-axis.

B. Concentration is plotted on the x-axis.

True, we vary the concentration and read the absorbance so the plot is Absorbance vs Concentration.

C. The x- and y-axes should be labeled with units as well as quantities

This is true for our plot to be useful and correct.

D. Concentration is plotted on the y-axis

False, for all the reasons stated above.

E. In a hand-plotted graph, individual lines should be drawn between adjacent points

False, in a hand plotted graph we will pass the line between all the points determined as close as to produce the best line where we can read values for the absorbance for a given concentration.

F. Absorbance is plotted on the y-axis

True

G. The command for getting an equation is "Add Trendline" in Microsoft Excel.

False, the command adds only the line of the best fit to our data, to get the equation of the line we have to specify it by choosing it in the options for the format of trendline.

The symbol for xenon (Xe) would be a part of the noble gas notation for the element antimony. cesium. radium. uranium.
nlexa [21]
The noble gas notation is the short or abbreviated form of the electron configuration.

It means that you use the symbol of the previous noble gas as part of the electron configuration of an element.

The gas noble previous to antimony is Kr, so you do not use Xe to write the electron configuration of Sb.

The gas noble previous to radium is Rn, so you do not use Xe to wirte the electron configuration of Ra.

The gas noble previous to uranium is Rn, so you do  not use Xe to write the electron configuration of U.

The gas noble previous to cesium is Xe, so you use Xe to write the noble notation for Sb. This is it: Cs: [Xe] 6s.

Answer: cesium

It takes 26.8 mL of a 0.0700 M NaOH standard solution to neutralize a 250 mL sample of lactic acid (C3H6O3). What mass of lactic
Butoxors [25]
There is 1 OH- in 1 molecule of NaOH. 
Also, there is 1 H+ in 1 molecule of lactic acid.

So the reaction is simple.
so just equate the moles
moles of OH- in NaOH = moles of H+ in lactic acid
26.8 x 0.07 = 250 x Mole of lactic
Moles of lactic = 0.0075

so mass = 0.0075 x 90.8 =  0.681 g
