i cut off C because i only need A&B
6.) (Modified from Chemistry, 7h Ed. by Chang) About half the hydrochloric acid produced annually in the US is used in metal pickling. This process involves removal of metal oxide layers from metal surfaces to prepare them for coating. (a) Write the overall and net ionic equations for the reaction between ferric oxide, which represents the rust layer over iron, and HCL. (1) HCl is also used to remove scale (mostly...
