Answer:

12.3 moles of $AlCl_{3}$ are produced by reacting 18.4 moles of $BaCl_{2}$ .

Explanation:

Balanced reaction: $2AlPO_{4}+3BaCl_{2}\rightarrow 2AlCl_{3}+Ba_{3}(PO_{4})_{2}$

According to balanced equation:

3 molecules of $BaCl_{2}$ produce 2 molecules of $AlCl_{3}$

So $3N_{A}$ molecules of $BaCl_{2}$ produce $2N_{A}$ molecules of $AlCl_{3}$ ( $N_{A}$ is avogadro number).

We know 1 mol of molecule = $N_{A}$ number of molecules.

So 3 moles of $BaCl_{2}$ produce 2 moles of $AlCl_{3}$ .

Hence 18.4 moles of $BaCl_{2}$ produce $(\frac{2}{3}\times 18.4)$ moles of $AlCl_{3}$ or 12.3 moles of $AlCl_{3}$ .

lions [1.4K]

Acetone has α-hydrogens (on both sides) and thus can be deprotonated to give a nucleophilic enolate anion. The aldehyde carbonyl is much more electrophilic than that of a ketone, and therefore reacts rapidly with the enolate.

<h3>What is nitrobenzaldehyde?</h3>

Synthesis. The synthesis of 3-nitrobenzaldehyde is achieved via nitration of benzaldehyde, which yields especially the meta-isomer. Creation allocation is about 19% for the ortho-, 72% for the meta- and 9% for the para isomers.

Acetone, propanone, or dimethyl ketone, is an organic combination with the formula (CH3)2CO. It is the easiest and smallest ketone. It is a colorless, highly volatile, and combustible liquid with a characteristic aromatic odor.

Nitration of benzene with conc nitric acid and conc sulphuric acid gives nitrobenzene. Chlorination with chlorine in the existence of anhydrous aluminum chloride gives meta nitro chlorobenzene.
