Answer:
1.BaCO3 2.MgBr2 3.aluminum and oxygen 4.Potassium chloride
Explanation:
Adding acid and and catching the solution that drains through.
When ketone is reacted with phosphorous pentachloride, chlorination takes place at the carbonyl carbon with substitution of the oxygen atom to give a geminal dichloride (with 2 Cl atoms on same carbon) according to the following equation:
so we can say that acetone is converted into 2,2-dichloropropane by action of PCl₅

Aluminum is 26.982 grams per mole, so 26.982/19.9 will give you the moles 1.3558794
