Many homeowners treat their lawns with CaCO3(s) to reduce
the acidity of the soil. The net ionic equation for the reaction of CaCO3(s)
with a strong acid, HCl (I chose HCl because it is a strong acid) is CaCO3(s) +2
HCl(aq) → CaCl2(s) + H2O(aq) + CO2(g).
36 grams of oxygen is the answer
Balanced Equation would be; 2N₂ + O₂ → 2N₂O
Hope this helps!
I think the correct answer from the choices listed above is option C. The atmosphere of Earth is an example of a gas-gas solution. The atmosphere is a mixture of different gases where oxygen is the most abundant substance. Hope this answers the question.
