Which is a correct representation of .000025 in scientific notation?

Answer : The correct answer is,

Explanation :

Scientific notation : It is the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.

For example :

8000 is written as

779.9 is written as

In this examples, 8000 and 779.9 are written in the standard notation and  and  are written in the scientific notation.

If the decimal is shifting to right side, the power of 10 is negative and if the decimal is shifting to left side, the power of 10 is positive.

As we are given the 0.000025 in standard notation.

Now converting this into scientific notation, we get:

As, the decimal point is shifting to right side, thus the power of 10 is negative.

Hence, the correct answer is,

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.
