question 8 (1 point)
water is a _________________ (polar/non-polar molecule)?(24)

question 9 (1 point)
an ionic compound that releases an hydrogen ion in solution is an _________________(24)

question 10 (1 point)
what is the normal ph of blood ?(24)

Explanation:

Analyze water polarity

Water molecules exhibit an uneven distribution of electron density. Oxygen is highly electronegative compared to hydrogen, pulling shared electrons closer to its nucleus. This creates partial negative charges near oxygen and partial positive charges near hydrogen, forming a polar molecule. This relates to Chemical Bonds.

Define hydrogen ion donors

An ionic compound that dissociates in water to release hydrogen ions \((\text{H}^+)\) is chemically defined as an acid. Acids increase the concentration of hydronium ions in a solution.

Determine blood pH range

Human physiological systems tightly regulate arterial blood pH to maintain homeostasis. The normal, slightly alkaline range for human blood pH is between 7.35 and 7.45.
