Answer:
5.19 x 10²³ molecules of H₂O
Explanation:
1 mole => 6.023 x 10²³ molecules of H₂O
0.861 mole => 0.861mole x 6.023 x 10²³ molecules of H₂O
= 5.19 x 10²³ molecules of H₂O
When two monosaccharides combine to make a disaccharide, water is the byproduct.
<h3>What are monosaccharides ?</h3>
The most fundamental building blocks from which all carbohydrates are constructed are monosaccharides, commonly known as simple sugars. They are the most basic types of sugar. They are typically crystalline solids, colorless, and soluble in water.
These three monosaccharides—glucose, fructose, and galactose—are crucial for nutrition. Six carbon atoms, twelve hydrogen atoms, and six oxygen atoms make up each single sugar molecule.

Answer:
c. Ice, H₂O, has a solid structure with alternating H−O interactions.
e. HF has a higher boiling point than HCl.
Explanation:
For molecules to interact through hydrogen bonding, it is required that there is an H atom bonded to a more electronegative atom, such as N, O or F.
<em>Select the interactions that can be explained by hydrogen bonding. Check all that apply.
</em>
<em>
a. CH₄ molecules interact more closely in the liquid than in the gas phase. </em>NO. The electronegativity of C is not high enough to form hydrogen bondings.
<em>b. HF is a weak acid neutralized by NaOH.
</em> NO. This reaction occurs in water and it is better explained by ion-ion forces.
<em>c. Ice, H₂O, has a solid structure with alternating H−O interactions.
</em> YES. This structure is a consequence of the hydrogen bonding.
<em>d. H₂Te has a higher boiling point than H₂S.</em> NO. The electronegativities of Te and S are not high enough to form hydrogen bondings.
<em>e. HF has a higher boiling point than HCl.</em> YES. The stronger hydrogen bonding interactions in HF explain the higher boiling point.
