Question

the table lists some compounds found in foods and their formulas. based on this information, which of these statements is not true? a a molecule of maltitol has twice as many atoms as a molecule of glucose does. b a molecule of xylitol contains half as many atoms as a molecule of glucose does. c a molecule of sucrose has twenty - three more atoms than a molecule of xylitol does. d a molecule of glucose has the same number of hydrogen atoms as a molecule of xylitol does.

Explanation:

Step1: Calculate atoms in glucose

For glucose ($C_6H_{12}O_6$), number of atoms = $6 + 12+6=24$.

Step2: Calculate atoms in maltitol

For maltitol ($C_{12}H_{24}O_{11}$), number of atoms = $12 + 24+11 = 47$.

Step3: Calculate atoms in xylitol

For xylitol ($C_5H_{12}O_5$), number of atoms = $5 + 12+5 = 22$.

Step4: Calculate atoms in sucrose

For sucrose ($C_{12}H_{22}O_{11}$), number of atoms = $12+22 + 11=45$.

Step5: Analyze Option A

Maltitol has 47 atoms and glucose has 24 atoms. 47 is not twice 24, so Option A is false.

Step6: Analyze Option B

Xylitol has 22 atoms and glucose has 24 atoms. 22 is not half of 24, so Option B is false.

Step7: Analyze Option C

Sucrose has 45 atoms and xylitol has 22 atoms. $45-22 = 23$, so Option C is true.

Step8: Analyze Option D

Glucose has 12 hydrogen - atoms and xylitol has 12 hydrogen - atoms, so Option D is true.

Answer:

A. A molecule of maltitol has twice as many atoms as a molecule of glucose does.
B. A molecule of xylitol contains half as many atoms as a molecule of glucose does.
