Write the ionic equation for these reaction.
Ca(HCO3)2 + HCL = CaCl2 + CO2 + H2O
ZnO + HNO3 = Zn(NO3)2 + H2O
Well, well, well...let's have some fun with these equations!
First, we have the reaction between Ca(HCO3)2 (calcium hydrogen carbonate) and HCl (hydrochloric acid).
Ca(HCO3)2 + 2HCl = CaCl2 + 2CO2 + 2H2O
Now, onto the next one. We have ZnO (zinc oxide) reacting with HNO3 (nitric acid).
ZnO + 2HNO3 = Zn(NO3)2 + H2O
Hope these equations brought a little laughter to your day!
To write the ionic equation for the given reactions, we need to first identify the ions present in the compounds.
1. Ca(HCO3)2 + HCl → CaCl2 + CO2 + H2O
The ions involved in this reaction are:
- Ca(HCO3)2 dissociates into Ca^2+ and HCO3^- ions.
- HCl dissociates into H^+ and Cl^- ions.
- CaCl2 dissociates into Ca^2+ and 2 Cl^- ions.
Therefore, the ionic equation for this reaction is:
Ca^2+ + 2 HCO3^- + 2 H^+ + 2 Cl^- → Ca^2+ + 2 Cl^- + CO2 + H2O
2. ZnO + HNO3 → Zn(NO3)2 + H2O
The ions involved in this reaction are:
- ZnO does not dissociate since it is a solid.
- HNO3 dissociates into H^+ and NO3^- ions.
- Zn(NO3)2 dissociates into Zn^2+ and 2 NO3^- ions.
Therefore, the ionic equation for this reaction is:
ZnO + 2 H^+ + 2 NO3^- → Zn^2+ + 2 NO3^- + H2O
To write the ionic equation for a chemical reaction, you need to first write the balanced molecular equation, which shows the reactants and products using their chemical formulas. Then, you separate the compounds that are soluble in water into their respective ions. Lastly, you write the net ionic equation by canceling out spectator ions - ions that do not participate in the chemical reaction.
1. Ca(HCO3)2 + HCl = CaCl2 + CO2 + H2O
Balanced molecular equation:
Ca(HCO3)2 + 2HCl = CaCl2 + 2CO2 + 2H2O
Ionic equation (with ions in water):
Ca2+(aq) + 2HCO3-(aq) + 2H+(aq) + 2Cl-(aq) = Ca2+(aq) + 2Cl-(aq) + 2CO2(g) + 2H2O(l)
Net ionic equation:
2HCO3-(aq) + 2H+(aq) = 2CO2(g) + 2H2O(l)
2. ZnO + HNO3 = Zn(NO3)2 + H2O
Balanced molecular equation:
ZnO + 2HNO3 = Zn(NO3)2 + H2O
Ionic equation (with ions in water):
Zn2+(aq) + O2-(aq) + 2H+(aq) + 2NO3-(aq) = Zn2+(aq) + 2NO3-(aq) + H2O(l)
Net ionic equation:
O2-(aq) + 2H+(aq) = H2O(l)
Remember, when writing an ionic equation, you need to consider the solubility of compounds in water and treat them accordingly. Compounds that exist as solids or are insoluble in water are not separated into ions.
I assume these are aqueous solutions as shown. Neither equation is balanced and I didn't balance either.
Ca(HCO3)2 + HCL = CaCl2 + CO2 + H2O
Ca(HCO3)2(aq) + HCl(aq) = CaCl2(aq) + CO2(g) + H2O(l)
Ca^2+(aq) + 2(HCO3)^-(aq) + H^+(aq) + Cl^-(aq) = Ca^2+(aq) + 2Cl^-(aq) + CO2(g) + H2O(l)
The ZnO equation is done the same way.
