Question

1. a substance dissociates into k⁺ and cl⁻ in solution. the substance is a(n) _______. a. acid b. base c. salt d. buffer 24. ty is three years old and as a result of a \stomach bug\ has been vomiting for about 24 hours. his blood ph is 7.48. what does this mean? a. tys blood is slightly acidic. b. tys blood is slightly alkaline. c. tys blood is highly acidic. d. tys blood is within the normal range 25. c₆h₁₂o₆ is the chemical formula for a _______. a. polymer of carbohydrate b. pentose monosaccharide c. hexose monosaccharide d. all of the above 26. what organic compound do brain cells primarily rely on for fuel? a. glucose b. glycogen c. galactose d. glycerol

Explanation:

Question 23:

Salts dissociate into cations and anions in solution. Here, the substance dissociates into $K^{+}$ (cation) and $Cl^{-}$ (anion), which is characteristic of a salt.

Question 24:

The normal blood pH range is about 7.35 - 7.45. A pH of 7.48 is slightly above this range, indicating slightly alkaline blood.

Question 25:

$C_{6}H_{12}O_{6}$ is the chemical formula for glucose, which is a hexose monosaccharide. Hexose means it has 6 - carbon atoms and monosaccharide means it is a single - sugar unit.

Question 26:

Brain cells primarily rely on glucose as a fuel source for energy production through cellular respiration.

Answer:

1. c. salt
2. b. Ty’s blood is slightly alkaline.
3. c. hexose monosaccharide
4. a. glucose
