Question

birch syrup contains glucose. the chemical formula for glucose is shown below.

\\\text{c}_6\text{h}_{12}\text{o}_6\text{ (s)}\\

in one molecule of glucose, the number of different elements is \\(i\\) and the total number of atoms is \\(ii\\).

the statement above is completed by the information in row

\

$$\begin{tabular}{|c|c|c|} \\hline \\textbf{row} & \\(i\\) & \\(ii\\) \\\\ \\hline \\bigcirc & 24 & 3 \\\\ \\hline \\bigcirc & 12 & 6 \\\\ \\hline \\bigcirc & 6 & 12 \\\\ \\hline \\bigcirc & 3 & 24 \\\\ \\hline \\end{tabular}$$

Explanation:

Identify the chemical formula

The chemical formula given for glucose is:

$$ \text{C}_6\text{H}_{12}\text{O}_6\text{(s)} $$

Determine the number of different elements

Using the Elements and Compounds knowledge point, we identify the unique chemical symbols in the formula:

• \(\text{C}\) represents Carbon.
• \(\text{H}\) represents Hydrogen.
• \(\text{O}\) represents Oxygen.

There are 3 different elements present in one molecule of glucose. Thus, \(i = 3\).

Calculate the total number of atoms

We sum the subscripts of each element in the chemical formula:

• Carbon atoms: 6
• Hydrogen atoms: 12
• Oxygen atoms: 6

$$ \text{Total atoms} = 6 + 12 + 6 = 24 $$

Thus, \(ii = 24\).

Match with the given options

We look for the row in the table where:

• \(i = 3\)
• \(ii = 24\)

This corresponds to the fourth row of the table.

Answer:

• Row 1: \(i = 24\), \(ii = 3\)
• Row 2: \(i = 12\), \(ii = 6\)
• Row 3: \(i = 6\), \(ii = 12\)
• Row 4: \(i = 3\), \(ii = 24\) (Correct answer)
