Answer:
See explanation.
Explanation:
Hello,
In this case, after looking for the information, the four cases and their discussion are:
a. Potassium carbonate and hydrochloric acid : in this case, the chemical reaction is:
[tex]K_2CO_3(aq)+2HCl(aq)-->2KCl(aq)+H_2O(l)+CO_2(g)[/tex]
Aqueous potassium chloride and water are formed and carbon dioxide is given off as gas due to the instability of the carbonic acid.
b. Zinc chloride and silver nitrate : in this case, the chemical reaction is:
[tex]ZnCl_2(aq)+2AgNO_3(aq)-->Zn(NO_3)_2(aq)+2AgCl(s)[/tex]
Aqueous silver nitrate is formed and solid silver chloride is precipitated out due to its low solubility in water.
c. Magnesium chloride and sodium hydroxide : in this case, the chemical reaction is:
[tex]MgCl_2(aq)+2NaOH(aq)-->2NaCl(aq)+Mg(OH)_2(s)[/tex]
Aqueous sodium chloride is formed and solid magnesium hydroxide is precipitated out due to its low solubility in water.
d. Ammonium nitrate and sodium hydroxide: in this case, the chemical reaction is:
[tex]NH_4NO_3(aq)+NaOH(aq)-->NaNO_3(aq)+NH_3(g)+H_2O(l)[/tex]
Sodium nitrate becomes aqueous as liquid water is formed and ammonia is given off as a gas due to the instability of the ammonium hydroxide.
Best regards.
