express the result of the following calculation in scientific notation: 0.0263 cm2÷ 88.2 cm
when i put into my calculator, i get 2.98^-2
how do i put in the calculator to get 2.98^-4cm

The result of the given calculation is

Explanation:

Scientific notation is defined as the notation in which a number is expressed in the decimal form. This means that the number is always written in the power of 10 form.

We are given an expression:

The operation carried out in the above expression is division operation. The units are also treated in the same way.

The solution for the above expression is:

The value in scientific notation is

Hence, the result of the given calculation is

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
