4 0

Answer:

c. 19

Explanation:

Potassium is a chemical element of the periodic table whose chemical symbol is K, whose atomic number is 19. It is an alkaline metal of white-silver color, which abounds in nature in the elements related to salt water and other minerals. It oxidizes rapidly in air, is very reactive, especially in water, and chemically resembles sodium. It is an essential chemical element.

The K having an atomic number of 19 means that it has 19 protons and in normal conditions for a neutral atom it will have 19 electrons, and being one step away from argon gas makes it extremely unstable.

What are the similarities between DIFFUSION, FACILITATED DIFFUSION and OSMOSIS?
nalin [4]
Osmosis and diffusion are related processes that display similarities. Both osmosis and diffusion equalize the concentration of two solutions. Both diffusion and osmosis are passive transport processes, which means they do not require any input of extra energy to occur. In both diffusion and osmosis, particles move from an area of higher concentration to one of lower concentration. Osmosis and facilitated diffusion both account for movement of molecules from a region of high concentration to a region of low concentration.

<h2>How Diamond and Graphite are chemically identical?</h2>
  • On heating diamond or graphite in the air, they burn completely to form carbon dioxide.
  • - Equal quantities of diamond and graphite when burned, produce exactly the same amount of carbon dioxide.

<h2>Why the physical properties of diamond and graphite are so different?</h2>

Due to the difference in the arrangement of carbon atoms in diamond and graphite

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
