na2s(aq)+Cu(no3)2(aq)→nano3(aq)+Cus(s) net ionic equation?

Answer 1

You would do well to find the caps key on your keyboard and use it. What do you not understand about this.
Here are the steps.
1. Write the molecular equation and balance it. You haven't balanced it yet.
2. Convert to the full ionic equation using the following rules:
a. Write as a molecule gases.
b. Write as a molecule insoluble materials.
c. Write as a molecule weak electrolytes; i.e., H2O, weak acid, weak bases.
d. Cancel any ions that appear on both the left and right sides of the equation.
e. What's left is the net ionic equation.
