Question

question 7 0.5 pts which of the following questions is/are true? there may be more than one true statement. each water molecule has regions of charge. when the ph value decreases, the acidity decreases. when water molecules \stick\ to other water molecules, this is called cohesion. a hydrogen bond is weak compared to a covalent bond. in the context of water molecules, hydrogen bonds are intramolecular bonds

Explanation:

• Water is a polar molecule, so it has regions of charge. This statement is true.
• A lower pH value indicates higher acidity, so the statement about pH and acidity decrease is false.
• Cohesion is the attraction between like - molecules, so water molecules sticking to other water molecules is cohesion (true).
• Hydrogen bonds are weaker than covalent bonds (true).
• In water molecules, hydrogen bonds are intermolecular bonds, not intramolecular. So the last statement is false.

Answer:

Each water molecule has regions of charge.
When water molecules “stick” to other water molecules, this is called cohesion.
A hydrogen bond is weak compared to a covalent bond.
