Classify the following substances into ionic, covalent, molecular or m

1.	Classify the following substances into ionic, covalent, molecular or metallic. MgO, SO_(2), I_(2) , H_(2)O("ice"), SiO_(2) (quartz), brass.
Answer» Solution :MGO= Ionic, ` SO_(2)` = Polar molecular , ` I_(2)` = non-polar molecuar, ` H_(2)O` = HYDROGEN bonded molecualar , ` SiO_(2)` = Covalent or network, BRASS = metallic.
