Question

1. choose the best answer.

look at the diagram. what does the diagram show?
hydrogen atoms are not perfectly held on opposite sides of oxygen.
hydrogen atoms are held at a 45° angle.
hydrogen atoms carry a strong negative charge.
hydrogen atoms have the same charge as oxygen atoms.

Explanation:

Step1: Analyze each option

• For the option "Hydrogen atoms are held at a \(45^{\circ}\) angle": The angle shown in the diagram is \(104^{\circ}\), not \(45^{\circ}\).
• For the option "Hydrogen atoms carry a strong negative charge": In a water molecule (\(H_2O\)), hydrogen atoms have a partial positive charge.
• For the option "Hydrogen atoms have the same charge as oxygen atoms": Oxygen has a partial negative charge and hydrogen has a partial positive charge in \(H_2O\).
• For the option "Hydrogen atoms are not perfectly held on opposite sides of oxygen": In a water molecule, due to the presence of lone pairs on oxygen, the hydrogen atoms are not in a linear (opposite - side) arrangement.

Answer:

Hydrogen atoms are not perfectly held on opposite sides of oxygen.
