Question

I really don't understand "Net Ionic Equations" could someone explain? For example KCl + Na2S?

Answer 1

Not sure what the question is but a net ion equation basically takes the charges into account so you can get the right subscripts before you balance the equation.

Answer 2

In other words, you look up the charges for each element. Each compound in the product needs to be electrically neutral. Also the elements with opposite charges will be the ones who combine in the product.
