A mixture could be homogeneous or heterogeneous.

A mixture refers to a combination of two or more substances that are not chemically combined together. They may be solids, liquids or gases.

A mixture may be composed of substances in the same phase or different phases. If substances are combined in the same phase to form a mixture then the mixture is homogeneous. If substances in different phases combine to give a mixture then the mixture is heterogeneous.

Examples of homogeneous mixtures are salt and water solutions while examples of heterogeneous mixtures are sand and water as well as oil and water.

mickey reacts magnesium with 1.0 M of hydrochloric acid. the reaction tales 2 minutes and 34 seconds to complete. what are 2 way
lutik1710 [3]

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.

Phenol and benzoic acid are both weak acids that are solublein
stealth61 [152]

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
