Explanation

First, let's understand the reaction between hydrochloric acid (HCl) and zinc (Zn). The balanced chemical equation for this reaction is:

\(Zn + 2HCl \rightarrow ZnCl_2 + H_2\)

From the balanced equation, we can see that 1 mole of zinc reacts with 2 moles of hydrochloric acid to produce 1 mole of hydrogen gas.

Now, we have 100 mL of 2 M hydrochloric acid, and we need to find the number of moles of HCl in this solution. To do this, we can use the formula:

Moles of solute = Molarity

Correct Answer: C) fertile males with reduced mouth parts

Explanation

In a honey bee colony, there are different types of bees with different roles to play. One of these types is the drones. The question is asking about the characteristics of drones in a honey bee colony. The first option states that drones are sterile males with reduced mouth parts, while the second option states that they are sterile males with well-developed mouth parts. However, both of these options are incorrect. The correct option is C, which states that drones are fertile males with reduced mouth parts. This means that drones are capable of fertilizing the queen bee but have limited ability to feed themselves. It is important to note that drones do not have a stinger and are solely responsible for mating with the queen bee. Once they have done so, they die shortly after. Overall, drones play an important role in the reproduction of a honey bee colony and their characteristics are unique to their specific role.
