D. Sucrose has a 1:1 ratio, maltose has a 1:2 ratio, glucose has a 1:1 ratio, fructose has a 2:2 ratio, water has a 2:1 ratio.

Answer 1

The ratio of hydrogen atoms to oxygen atoms in maltose is 2:1, which also applies to sucrose, glucose, fructose, and water.

Step-by-step explanation:

The disaccharide maltose is formed from two glucose monosaccharides, which are hexose sugars. Each glucose molecule contains 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. Therefore, maltose, being formed from two glucose molecules, contains 12 carbon atoms, 24 hydrogen atoms, and 12 oxygen atoms. The ratio of hydrogen atoms to oxygen atoms in maltose is 24:12, which simplifies to 2:1.

Comparing the ratio of hydrogen to oxygen atoms in other molecules, we find that sucrose, glucose, fructose, and water all have a 2:1 ratio. So, the correct answer is option A: Sucrose has a 2:1 ratio, maltose has a 2:1 ratio, glucose has a 2:1 ratio, fructose has a 2:1 ratio, water has a 2:1 ratio.
