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_2O (ice) , SiO_2 (quartz), brass.
Answer» Solution :MgO=Ionic, `SO_2`=Polar MOLECULAR , `I_2`=non-polar molecular , `H_2O` = Hydrogen BONDED molecular , `SiO_2`=COVALENT or network, brass=metallic
