Ionic is the transference of electrons and covalent is sharing 
Also ionic is with metals and non-metals and covalent is just non-metals

Ionic bonds will be a metal + a nonmetal, and electrons are transferred from the metal to the nonmetal.

A covalent bond will be a nonmetal only. Nonmetals will not give up their electrons so electrons are shared.

I have also written this on the whiteboard in the image provided.

The amount of protein in a sample was measured by the sample's absorbance of light at a given wavelength. Using standards, a bes
FinnZ [79.3K]

Answer:

Protein Concentration is 2.82mg/L

Explanation:

According to Beer-Lambert's Law, Absorbance is directly proportional to the concentration.

However, the concentration of a solution can be determined from a calibration curve, in which Absorbance is plotted on the y-axis and the Concentration on the x-axis.

Plotting the best line, the equation of line is used

y = mx + c

where y is absorbance = 0.150

           m is slope = 0.0163

            x is concentration

             c is intercept = 0.104

inserting the values from the question

y = mx + c

0.150 = 0.0163x + 0.104

0.0163x = 0.150 - 0.104

0.0163x = 0.046

Divide both sides by 0.0163

0.0163x/0.0163 = 0.046/0.0163

x = 2.82

Concentration of protein = 2.82 mg/L
