In the following reaction, if you wanted to produce more chlorine gas (Cl2), what should you do? (2 points) 4HCl + O2 ⇄ 2H2O + Cl2

a
Add more H2O

b
Remove HCl

c
Remove O2

d
Add more HCl

The study of chemicals and bonds is called chemistry.

The correct answer is D.

According to the Charlier principle, the reaction will shift to the formation of the product when the amount of reactant is more.

According to the question, we have to produce more Cl in the given reaction.

.

To increase the amount of chlorine in the equation, we have to increase the HCl in the equation because the Chlorine gas is evolved from the HCl.

Hence, the correct answer is D.

d. Add more HCl

Explanation:

To produce more Cl₂ gas, it is best to add more HCl to the reaction. In this way more products will be formed.

According to the Le Chatelier's principle "if the conditions of equilibrium is changed, the system will adjust itself in order to annul the effect of the change".

the correct answer is:

a. formation of precipitation

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
