The following chemical reaction takes place in aqueous solution:

Cu(NO3)2(aq) + Na2S(aq) (right arrow) CuS(s) + 2NaNO3(aq)

Write the net ionic equation for this reaction.

science chemistry

Answer 1

Answer #1

Cu(NO3)2_(aq) + Na2S_(aq) -------------> CuS_(s) + 2NaNO3_(aq)

first write complete ionic equation

Cu⁺²_(aq) + 2NO3^-_(aq) + 2Na⁺_(aq) + S^-2_(aq) ------------> CuS_(s) + 2Na⁺_(aq) + 2NO3^-_(aq)

now cancel spectator ions. we will get net-ionic equation

Cu⁺²_(aq) + S^-2_(aq) ------------> CuS_(s) net -ionic equation.
