Scientists often deal with numbers that are either very large or very small. for example, 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.

696,000 = 6.96 x 10^5 & 1.9 x 10^-4 = 0.00019

Explanation:

For the first number, we can convert it from standard form to scientific notation. To do this, we can move the decimal at the beginning of the number to a place where the digits next to it are from 1-10. Moving the decimal between 6 and 9 would be correct because both of the digits are from 1-10. Because we moved the decimal five times to the right, we make the exponent of 10, 5.

For the second number, we can convert it from scientific notation to standard form by moving the decimal in 1.9 to the left 4 times to get 0.00019.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
