Explanation:

Salt

Step1: Identify elements

From the formula \(NaCl\), the elements are Sodium (\(Na\)) and Chlorine (\(Cl\)).

Step2: Count atoms

In \(NaCl\), there is 1 atom of \(Na\) and 1 atom of \(Cl\).

Step3: Find a fact

Salt (\(NaCl\)) is used to season food.

Sugar

Step1: Identify elements

From the formula \(C_{12}H_{22}O_{11}\), the elements are Carbon (\(C\)), Hydrogen (\(H\)), and Oxygen (\(O\)).

Step2: Count atoms

There are 12 atoms of \(C\), 22 atoms of \(H\), and 11 atoms of \(O\).

Step3: Find a fact

Sugar (\(C_{12}H_{22}O_{11}\)) is a source of energy.

Alcohol

Step1: Identify elements

From the formula \(C_{2}H_{5}OH\) (which can be written as \(C_{2}H_{6}O\)), the elements are Carbon (\(C\)), Hydrogen (\(H\)), and Oxygen (\(O\)).

Step2: Count atoms

There are 2 atoms of \(C\), 6 atoms of \(H\), and 1 atom of \(O\).

Step3: Find a fact

Alcohol (e.g., ethanol \(C_{2}H_{6}O\)) is used in beverages (in appropriate concentrations) and as a solvent.

Vinegar (acetic acid)

Step1: Identify elements

From the formula \(CH_{3}COOH\) (which can be written as \(C_{2}H_{4}O_{2}\)), the elements are Carbon (\(C\)), Hydrogen (\(H\)), and Oxygen (\(O\)).

Step2: Count atoms

There are 2 atoms of \(C\), 4 atoms of \(H\), and 2 atoms of \(O\).

Step3: Find a fact

Vinegar (acetic acid \(C_{2}H_{4}O_{2}\)) is used in cooking for flavoring and as a preservative.

Baking Soda

Step1: Identify elements

From the formula \(NaHCO_{3}\), the elements are Sodium (\(Na\)), Hydrogen (\(H\)), Carbon (\(C\)), and Oxygen (\(O\)).

Step2: Count atoms

There is 1 atom of \(Na\), 1 atom of \(H\), 1 atom of \(C\), and 3 atoms of \(O\).

Step3: Find a fact

Baking soda (\(NaHCO_{3}\)) is used in baking to make dough rise.

Carbon Dioxide

Step1: Identify elements

From the formula \(CO_{2}\), the elements are Carbon (\(C\)) and Oxygen (\(O\)).

Step2: Count atoms

There is 1 atom of \(C\) and 2 atoms of \(O\).

Step3: Find a fact

Carbon dioxide (\(CO_{2}\)) is used in fire extinguishers.

Ammonia

Step1: Identify elements

From the formula \(NH_{3}\), the elements are Nitrogen (\(N\)) and Hydrogen (\(H\)).

Step2: Count atoms

There is 1 atom of \(N\) and 3 atoms of \(H\).

Step3: Find a fact

Ammonia (\(NH_{3}\)) is used in the production of fertilizers.

Glucose

Step1: Identify elements

From the formula \(C_{6}H_{12}O_{6}\), the elements are Carbon (\(C\)), Hydrogen (\(H\)), and Oxygen (\(O\)).

Step2: Count atoms

There are 6 atoms of \(C\), 12 atoms of \(H\), and 6 atoms of \(O\).

Step3: Find a fact

Glucose (\(C_{6}H_{12}O_{6}\)) is the main source of energy for cells in the human body.
