Answer: chemical energy to mechanical energy

Explanation: potential energy is the energy a body has when it's at rest it a mean position.

Kinetic energy is the energy a body posses when it's in motion or been heated

For a person taking a race course, he is first at a resting position possessing potential energy in form of chemical energy is now been converted to mechanical energy which is used to run.

Energy is stored as chemical energy in the body because it is gotten from food and water eaten.

When activities are been carried out it is converted to kinetic energy

The empirical formula of styrene is ch; its molar mass is 104.1 g/mol. what is the molecular formula of styrene? select one:
Nuetrik [128]
The empirical formula is a formula of a compound showing the proportion of each element involved in the compounds but it does not represent the total number of atoms in the compound. It is the lowest number of ratio between the elements in the compound. In order, to determine the actual number of the atoms or the molecular formula of the compounds, we make use of the molar mass of the compound. 

<span>To determine the molecular formula, we multiply a value to the empirical formula. Then, calculate the molar mass and see whether it is equal to the one given (104.1 g/ mol). From the choices, the only valid options are b, d and e.
</span>                  molar mass
1     CH          13.02
8   C8H8      104.16
6   C6H6      78.12

Therefore the correct answer is option B.
