4 0
The answer should be <span>balance electrically

</span><span>Chemical reactions that form ions should have a balanced charge. The example of the reaction is HCl. When forming ions, the equation should be:
HCl => </span>H^{+} + Cl^{-}
In this case, the hydrogen has one plus charge and chlorine has one negative charge. The resultant should be zero, so it's balanced.

Arrange the following molecules according to the strength of their dispersion forces. Organize in order from largest to smallest
ki77a [65]

Explanation:

The weak intermolecular forces which can arise either between nucleus and electrons or between electron-electron are known as dispersion forces. These forces are also known as London dispersion forces and these are temporary in nature.

Therefore, more is the surface area occupied by the carbon chain more will be the dispersion forces present in it. Hence, less is the surface area occupied by a molecule less will be the dispersion forces present in it.  

Hence, the given molecules are organized from largest to smallest dispersion forces as follows.

CH_{3}CH(CH_{3})C(CH_{3})_{2}CH_{2}CH_{3} > CH_{3}CH_{2}(CH_{2})_{4}CH_{2}CH_{3} > CH_{3}CH_{2}CH_{2}CH_{2}CH_{3} > CH_{3}C(CH_{3})2CH_{3} > CH_{3}CH_{2}CH_{3} > CH4

mylen [45]

He can conclude that his experiment has very low precision.

<h3>What is Precision ?</h3>

Precision is defined as the degree of refinement with which an operation is performed or a measurement .

Precision is how close the exact answers are together.

As, the answers are increasing in time.

None of the answers are similar to one another.

Hence, He can conclude that his experiment has very low precision.
