7) A high-school chemistry student performed an acid-base reaction in class and wanted to determine the pH of the resulting solution. The student knows that the concentration of
hydroxide ions, [OH-], in the solution is 5.2 x 10-3 M. What is the pH of this solution?
Choose the range of pH values that contains the correct pH.
A) 1-3.9
B) 4 - 7.9
C) 8-11.9
D) 12 - 14

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

it's c. elements are placed in rows based on how may valencies electrons have.

answer: they produce more slow than unicellular organisms.
