I think the answer is a, that is the only one that makes sense.
Arrhenius Bases, so that other compounds that have the hydroxyl group (OH⁻)

Answer: A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell. They store solutes, regulate cell turigidity, maintain balance. Vacuoles in animals store and breakdown food brought in through phagocytosis, also involved in recycling of molecular components (Autophagy). Assist lysosomes in digestion of food materials and organelles.

1 mole C6H12O6 -------------- 180.15 g
? moles C6H12O6 ------------ 523.46 g
523.46 x 1 / 180.15 => <span>2.905 moles</span>
A chemical change is characterized of the formation of new substances or a chemical reaction. There are a number of observations that we can see if this type of change happens. One would be the formation of gas bubbles, this indicates that one of the products is a gas. Another observation would be a formation of a precipitate in the solution, it would indicate that the new solid formed is not soluble in the solution. A permanent color change in the solution would also indicate a chemical change because it may be that the new substance that is formed has its own distinct color when in solution.
