I think its time isn't a unit
Answer:
Explanation:
To slow down this reaction, we can use any of the methods listed below:
- Increase the size of the magnesium by using solid lumps of the metal. This will take a much faster time to react than powered and granulated magnesium.
- Reduce the concentration of the acid.
- Let the reaction take place at a much lower temperature than that given.
These conditions will slow down a chemical reaction.
Answer:
Se explanation below
Explanation:
Here we will use the technique of extraction taking advantange of the different solubilities of Phenol and and Benzoic Acid in the NaOH and and NaHCO₃ solvents (In reality their anions). Notice that phenol does not dissolve in the weak base NaHCO₃ so we can have the solution of phenol and benzoic acid in ether and proceed to extract with this weak base, the phenol will remain in solution in the organic ether solution and the sodium benzoate will go into the water layer.
We then will repeat the extraction procedure to separate the phenol from the organic layer by using NaOH instead.
Benzoic Acid /
Phenol/ Ether ⇒Extract w/ ⇒ Organic Layer = Phenol/Ether
10 % NaHCO₃ Aqueous Layer = Sodium Benzoate
Sodium benzoate ⇒ 10 % HCl to precipitate Benzoic Acid
Filter Precipitate benzoic Acid ⇒ Recrystallize benzoic Acid
Phenol / Ether Extract w/ Organic Layer = Eher
10 % NaOH Aqueous Layer =
Sodium Phenolate
Sodium Phenolate ⇒ 10% HCl to precipitate Phenol Filter Precipitate Phenol ⇒ Recrystallize Phenol
Ik the answer but you said 50 points but it’s only worth 5♀️
