1) Aqueous solutions of potassium sulfate and ammonium nitrate are
mixed together. Which statement is correct?
A) Both KNO3 and NH4SO4 precipitate from solution
B) A gas is released
C) NH4SO4 will precipitate from solution
D) KNO3 will precipitate from solution
E) No reaction will occur
E is the only correct one.
However, your statements don't match the answers. Potassium sulfate is K2SO4 and ammonium nitrate is NH4NO3. Another error is ammonium sulfate is (NH4)2SO4.
Answer E
E) No reaction will occur
Well, it seems like the potassium sulfate and ammonium nitrate are just going to have a friendly get-together in the aqueous solution. No precipitates forming, no gas being released, just a good old mix and mingle.
To determine the correct statement, we need to examine the reaction between potassium sulfate (K2SO4) and ammonium nitrate (NH4NO3).
The chemical equation for the reaction can be written as follows:
K2SO4(aq) + 2NH4NO3(aq) → 2KNO3(aq) + (NH4)2SO4(aq)
From this equation, we can analyze each statement:
A) Both KNO3 and NH4SO4 precipitate from solution:
According to the balanced chemical equation, the products of the reaction are potassium nitrate (KNO3) and ammonium sulfate (NH4)2SO4. However, both of these compounds remain in aqueous solution, indicating that there is no precipitation. Therefore, statement A is incorrect.
B) A gas is released:
Looking at the chemical equation, we can see that there are no gas molecules listed as reactants or products. Therefore, statement B is incorrect.
C) NH4SO4 will precipitate from solution:
Again, examining the chemical equation, we see that ammonium sulfate (NH4)2SO4 is formed as a product. However, it remains in solution and does not precipitate. Thus, statement C is incorrect.
D) KNO3 will precipitate from solution:
Based on the chemical equation, one of the products is potassium nitrate (KNO3), but it remains soluble and does not form a solid precipitate. Therefore, statement D is incorrect.
E) No reaction will occur:
According to the balanced chemical equation, the reactants (K2SO4 and NH4NO3) do indeed react to form products (KNO3 and (NH4)2SO4). Thus, a reaction will occur, and statement E is incorrect.
In conclusion, none of the given statements are correct. The correct answer would be "None of the above."
