How does the written Lewis structure for potassium chloride differ from that of hydrogen chloride?
Thanks!

In the following reactions, label the substance oxidized and the substance reduced.

a.) ZnO + C= Zn + CO

b.) 8Fe + S = FeS

Thanks so Much! What about..(NH4)3PO4(aq)+LiOH=?

Li(s) + S(s)=

Complete and balance the following equation.
