The radius of the sun is approximately 696,000 kilometers, while bacterial cells are as small as 1.9 × 10-4 millimeters. express each of these numbers in an alternate form in scientific notation

Explanation;

Writing scientific notation :

Radius of the sun = 696,000.0 kilometer

Radius of the sun can also be written as =

Size of bacterial cell = millimeter

Size of bacterial cell can also be written as =

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
