Question
The reaction of nitric acid with calcium carbonate produces calcium nitrate, carbon dioxide, and water. Determine the correct balanced equation for this reaction.
|
2HNO3(aq) + CaCO3(s) → CaNO3(aq) + CO2(g) + H2O(l)
|
|
HNO3(aq) + CaCO3(s) → Ca(NO3)2(aq) + CO2(g) + H2O(l)
|
|
2HNO3(aq) + CaCO3(s) → Ca(NO3)2(aq) + CO2(g) + H2O(l)
|
|
2HNO3(aq) + 2CaCO3(s) → 2Ca(NO3)2(aq) + 2CO2(g) + 2H2O(l) |
