to make a water molecule, ________ bonds are formed between h and o atoms. these water molecules then form ________ bonds between themselves.
nonpolar covalent; hydrogen
nonpolar covalent; ionic
polar covalent; ionic
polar covalent; hydrogen

Explanation:

• Question 1: Mechanical energy is the energy of motion, and when legs move to run, they provide mechanical energy.
• Question 2: In a suspension, solute particles are large and can settle out over time, which is true for blood.
• Question 3: Water molecules are formed by polar - covalent bonds between H and O atoms, and water molecules form hydrogen bonds with each other.

Answer:

Question 1: B. Mechanical
Question 2: B. Suspension
Question 3: D. Polar covalent; Hydrogen
