Question

Aqueous copper (II) nitrate, Cu(NO3)2 reacts with aqueous potassium carbonate, K2CO3 forming solid copper (II) carbonate, Cu(CO3).

Answer 1

Cu(NO3)2 (aq) + K2CO3 (aq) => CuCO3 (s) + 2KNO3 (aq)

Step-by-step explanation:

I interpret your question is how to balance the above reaction, right?

Cu(NO3)2 (aq) + K2CO3 (aq) => CuCO3 (s) + 2KNO3 (aq)

Cu: 2

NO3: 2

K: 2

CO3: 2
