An amount of 5 moles of

\text{A,}

6 moles of

\text{B}

and excess amount of

\mathrm{C}

are mixed to produce a final product

\mathrm{D}

, according to the following reactions.

\begin{aligned} & \mathrm{A}+2 \mathrm{B} \rightarrow \mathrm{I} \\ & \mathrm{I}+\mathrm{C} \rightarrow \mathrm{B}+\mathrm{D} \end{aligned}

What is the maximum moles of

\mathrm{D},

which can be produced assuming that the products formed can also be reused in the reactions?

View answer and explanation

Correct option: C

5 moles

Option C (A is true but R is false) is correct because HBF4 is a strong acid, but the given reaction of B(OH)3 with HF doesn't explain why HBF4 is a strong acid.
