Using the balanced reaction, enter the formula, charge(if any), and state of the species (exclude H2O) in solution if ZnCl2(aq) reactant is present in stoichiometric excess. Separate your answers by comma.
ZnCl2(aq) + K2CO3(aq) → ZnCO3(s) + 2KCl(aq)
Separate the aq compounds into their ions. That's all there is to it.
To determine the formula, charge (if any), and state of each species in the reaction if ZnCl2(aq) is present in stoichiometric excess, we can look at the balanced equation:
ZnCl2(aq) + K2CO3(aq) → ZnCO3(s) + 2KCl(aq)
Since ZnCl2 is in excess, it means that there is more than enough ZnCl2 to react with K2CO3, and it will not be completely consumed in the reaction.
Let's start by identifying the species involved in the reaction and their formulas:
1. ZnCl2: This represents zinc chloride, where Zn is the symbol for Zinc and Cl is the symbol for chlorine. The formula for zinc chloride is ZnCl2.
2. K2CO3: This represents potassium carbonate, where K is the symbol for potassium and CO3 is the carbonate ion. The formula for potassium carbonate is K2CO3.
3. ZnCO3: This represents zinc carbonate, where Zn is the symbol for Zinc and CO3 is the carbonate ion. The formula for zinc carbonate is ZnCO3.
4. KCl: This represents potassium chloride, where K is the symbol for potassium and Cl is the symbol for chlorine. The formula for potassium chloride is KCl.
Now, let's determine the charges (if any) and states of each species:
1. ZnCl2(aq): ZnCl2 is in aqueous (aq) state, meaning it is dissolved in water. Zinc chloride, ZnCl2, dissociates into Zn2+ and 2 Cl- ions in solution.
2. K2CO3(aq): K2CO3 is also in aqueous (aq) state, indicating it is dissolved in water. Potassium carbonate, K2CO3, dissociates into 2 K+ ions and 1 carbonate (CO3^2-) ion in solution.
3. ZnCO3(s): ZnCO3 is in solid (s) state, implying that it is not dissolved and exists as a solid precipitate.
4. 2KCl(aq): 2KCl is in aqueous (aq) state, meaning it is dissolved in water. Potassium chloride, KCl, dissociates into 2 K+ and 2 Cl- ions in solution.
In summary, when ZnCl2(aq) is present in stoichiometric excess in the reaction ZnCl2(aq) + K2CO3(aq) → ZnCO3(s) + 2KCl(aq), the formula, charge (if any), and state of the species are:
ZnCl2(aq): Zinc chloride, ZnCl2, in aqueous state (dissolved in water), dissociates into Zn2+ and 2 Cl- ions.
K2CO3(aq): Potassium carbonate, K2CO3, in aqueous state (dissolved in water), dissociates into 2 K+ ions and 1 carbonate (CO3^2-) ion.
ZnCO3(s): Zinc carbonate, ZnCO3, in solid state (solid precipitate).
2KCl(aq): Potassium chloride, KCl, in aqueous state (dissolved in water), dissociates into 2 K+ and 2 Cl- ions.
