Final answer:
False. The number 0.000027 is not expressed in Engineering Notation but is correctly expressed as 2.7 × 10^-5 in Scientific Notation, which is used for handling very large or very small numbers like those found in chemistry.
Step-by-step explanation:
The statement that the number 0.000027 is equal to 2.7 × 10^-5 in Engineering Notation is false. In Engineering Notation, numbers are typically written in powers of three exponentials such as 10^3, 10^6, 10^9, etc. However, the correct expression in Scientific Notation for 0.000027 is indeed 2.7 × 10^-5, where the first digit should be non-zero and it should be followed by a decimal point and the rest of the significant figures. This follows the standard formatting for expressing small numbers in scientific notation, which is commonly used in fields like chemistry to make calculations with very large or very small numbers more manageable.
As an example, the number 56900 can be written as 5.69 × 10^4 in Scientific Notation, demonstrating the same format where a non-zero digit is followed by the decimal point and other significant figures, with the exponent reflecting the number of places the decimal point has been moved.
