Chapter 18.1, Problem 6R

To determine

The elements that are present in the compound ${\text{CH}}_{\text{3}}\text{COOH}$ and how many atoms of each element can be found in a unit of ${\text{CH}}_{\text{3}}\text{COOH}$ .

Answer to Problem 6R

The elements present in this compound are carbon (C), Hydrogen (H) and oxygen (O). For each unit of carbon and oxygen atom, there are 2 units of hydrogen atoms.

Explanation of Solution

Given:

The given compound is ${\text{CH}}_{\text{3}}\text{COOH}$ .

Calculation:

Molecules which are formed by the atoms with more than one element through a chemical bond are known as chemical compound.

The label on the box shows ${\text{CH}}_{\text{3}}\text{COOH}$ , which is called as acetic acid also known as vinegar.

Therefore, the elements present in this compound are carbon (C), Hydrogen (H) and oxygen (O).

The compound shows the presence of 2 carbon atoms, 4 hydrogen atoms and 2 oxygen atoms. Therefore, for each carbon and oxygen atom, there are 2 hydrogen atoms.

Conclusion:

Hence, the elements present in this compound are carbon (C), Hydrogen (H) and oxygen (O). For each unit of carbon and oxygen atom, there are 2 units of hydrogen atoms.
