Correct Line Notation Answers:<\/h3>\n\n\n\n

Left Galvanic Cell:<\/strong>
FeO(s) | Fe(s) || KOH(aq) || Ag(s) | Ag\u2082O(s)<\/p>\n\n\n\n

Right Galvanic Cell:<\/strong>
Cu(s) | Cu\u00b2\u207a(1 M) || NO\u2083\u207b(aq) || Ag\u207a(1 M) | Ag(s)<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

Line notation is a concise way of describing a galvanic or voltaic cell. It shows the substances involved in the redox reaction and the direction in which electrons flow. The notation always starts with the anode (where oxidation occurs) and ends with the cathode (where reduction occurs). Vertical lines separate different phases such as solids and aqueous solutions, while double vertical lines represent the salt bridge.<\/p>\n\n\n\n

In the left cell<\/strong>, iron(II) oxide (FeO) is in contact with potassium hydroxide (KOH), forming a basic medium. Here, FeO loses electrons and is oxidized to Fe metal. This makes the Fe electrode the anode. Silver(I) oxide (Ag\u2082O) is reduced to metallic silver, making the Ag electrode the cathode. The full cell reaction involves the transfer of electrons from Fe to Ag. The salt bridge maintains charge balance, allowing ions to flow between the half-cells. The line notation begins with the anode material FeO(s), then the solid Fe produced, then the electrolyte KOH(aq), and finally the cathode substances Ag(s) and Ag\u2082O(s).<\/p>\n\n\n\n

In the right cell<\/strong>, copper metal is oxidized to copper ions (Cu\u00b2\u207a) in solution. This makes copper the anode. Silver ions (Ag\u207a) from the 1 M solution are reduced to silver metal, making silver the cathode. The nitrate ions (NO\u2083\u207b) serve to balance charge but do not participate directly in the redox reaction. The salt bridge ensures electrical neutrality by allowing ion flow. The line notation for this cell starts with Cu(s), followed by Cu\u00b2\u207a(1 M), then the salt bridge NO\u2083\u207b(aq), and ends with Ag\u207a(1 M) and Ag(s).<\/p>\n\n\n\n

This notation clearly shows the electrochemical process and helps chemists understand how electrons and ions move within the cell.<\/p>\n\n\n\n
