In this equation: FeBr2+K2CO3=Fe2(CO3)2+KBr do I simplify the 2's on iron and the CO3 on the "right side" before continuing or keep them and why?

Respuesta :

Yes simplify. Anybody educated in chemistry can look at the equation and see that you have Fe+2 and CO3-2 combined to make FeCO3. But you don't need the 2s. Always simplify the subscripts.

By the way, the equation is not fully balanced. Check KBr.
