Answer 1

$\huge\boxed{\fcolorbox{red}{ink}{SOLUTION:}}$

▬▬▬▬▬▬▬▬▬▬▬▬

1 .Basic anhydride of Calcium hydroxide.

• e.g., calcium oxide CaO
• sodium oxide (Na2O) or magnesium oxide (MgO)

▬▬▬▬▬▬▬▬▬▬▬▬

2. A material used for making non-attackable

• unreactive elements like Pt, graphite etc. and electrodes which do not dissolve and their mass remain same.

▬▬▬▬▬▬▬▬▬▬▬▬

3. A molecule with 2 lone pairs and 2 bond pairs. electrodes.

• sp2 hybridized central atoms for only possible molecular geometry
