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

Explanation:

Step1: Recall scientific - notation form

Scientific notation is $a\times10^{n}$, where $1\leqslant|a|\lt10$ and $n$ is an integer.

Step2: Convert 0.00000000003 to scientific notation

Move the decimal point 11 places to the right to get $a = 3$ and $n=-11$, so it is $3\times10^{-11}$.

Step3: Analyze each statement

  • The exponent $n=-11$ is negative, so "The exponent is negative" is correct.
  • Since the exponent is negative, "The exponent is positive" is incorrect.
  • The coefficient $a = 3$, not 0.3, so "The coefficient is 0.3" is incorrect.
  • The exponent $n$ represents the number of places the decimal moves. Here $n=-11$ means the decimal moves 11 places, so "The exponent represents the number of places the decimal moves" is correct.
  • To convert 0.00000000003 to scientific - notation, we move the decimal to the right to get a number between 1 and 10, so "The decimal moves to the right" is correct.

Answer:

The exponent is negative., The exponent represents the number of places the decimal moves., The decimal moves to the right.
