Converting to Scientific Notation
Nitrogen and oxygen are the most abundant gases in Earth’s atmosphere. A nitrogen molecule is 0.00000000003 meters larger than an oxygen molecule.

Which statements describe writing 0.00000000003 in scientific notation? Check all that apply.
The exponent is negative.
The exponent is positive.
The coefficient is 0.3.
The exponent represents the number of places the decimal moves.
The decimal moves to the right.

Answer 1

Correct choices:
- The exponent is negative.
- The exponent represents the number of places the decimal moves.
- The decimal moves to the right.

Explanation: 0.00000000003 = 3 × 10^−11, so the coefficient is 3 (not 0.3), the exponent is −11 (not positive), and it tells you to move the decimal 11 places (you move it to the right to get 3).
