Answer:
D) SrCO3(s) + 2 HNO2(aq) → Sr(NO2)2 + H2O + CO2(g)
Explanation:
When an acid react with carbonate, it produces nitrate, carbon-dioxide gas and water molecule. When nitrous acid react with Strontium carbonate, three products are formed i. e. Strontium nitrate, carbon-dioxide gas and water. In the reaction, both nitrous acid and Strontium carbonate exchange their partners with each other and forming a different products.
Answer:
Option E is correct.
The net ionic equation is given as
SrCO₃(s) + 2H⁺ → Sr²⁺ + H₂O + CO₂(g)
Explanation:
When acids react with carbonate compounds, it leads to the liberation of CO₂, hence, when an aqueous solution of HNO₂ is poured onto a solid pile of SrCO₃, the balanced overall equation is given as
SrCO₃(s) + 2HNO₂(aq) → Sr(NO₂)₂ + H₂O + CO₂(g)
But for the net ionic reaction, it is obtained by eliminating ions that occur on both sides of the overall reaction. Note that ions exist onlubone the aqueous compounds.
Hence, the two aqueous compounds that exist in the balanced overall equation are
2HNO₂(aq) on the left hand side and Sr(NO₂)₂ on the right hand side
In their ionic form, 2HNO₂ ⇌ 2H⁺ + 2NO₂⁻
And Sr(NO₂)₂ ⇌ Sr²⁺ + 2NO₂⁻
And it is evident that the ion that occurs on both sides and needs to be deleted is NO₂⁻,
Hence, the net ionic equation is
SrCO₃(s) + 2H⁺ → Sr²⁺ + H₂O + CO₂(g)
Hope this Helps!!!
