Question- Write a balanced net ionic equation for the reactions, if any, that occur between (a) FeS(s) and HBr(aq); (b) K2CO3(aq) and CuCl2(aq); (c) Fe(NO3)2(aq) and HCl(aq); (d) Bi(OH)3(s) and HNO3(aq). Please show me molecular to complete ionic to net ionic as I need to
understand how to do this, not just the answers. Thank you Please answer only if you are 100% confident
