Answer:
First, precipitate of AgCl is formed. Second, a soluble complex of silver and ammonia is formed. Third, AgCl is reproduced due to disappearance of ammonia complex in presence of .
Explanation:
In presence of NaCl, forms an insoluble precipitate of AgCl.
Reaction:
In presence of , AgCl gets dissolved into solution due to formation of soluble complex.
Reaction:
In presence of , complex gets destroyed and free again reacts with free to produce insoluble AgCl
Reaction:
The balanced reaction would be written as:
C7H6O3 + C4H6O3--->C9H8O4 + HC2H3O2
To determine the percent yield, we need to first determine the theoretical yield if the reaction were to proceed completely. Then, we divide the actual yield that is given to the theoretical yield times 100 percent. The limiting reactant from the reaction would be salicylic acid. We do as follows:
Theoretical yield: 1.23 g C7H6O3 ( 1 mol / 138.21 g ) ( 1 mol C9H8O4 / 1 mol C7H6O3 ) ( 180.157 g / mol ) = 1.60 g <span>C9H8O4 should be produced
Percent yield = 1.39 / 1.60 x 100 = 86.88%
Thus, only 86.88% of the theoretical </span><span>C9H8O4 is being produced.</span>
5 because the dividing by 2
Answer is: distillation.
Solution of sugar and water has a uniform composition and is able to be separated by physical means.
Solution is homogeneous mixture has the same proporties of its components throughout any given sample.
Solution of water and salt, can be separated with distillation (process of heating and cooling). Water evaporates and sugar remain in the beaker.
