amagnesium oxide, MgO ionic bStrontium chloride, SrCl2 ionic cOzone, O3 covalent dMethanol, Ch4 O covalent 2) aluminum foil (aluminum is held by metallic bond, hence with the presence of the 'sea of electrons' , it is able to carry the current KOH dissolve in water is aqueous to give K+ and OH- the mobile ions can carry current 3) can't draw it here 4) yessilver is held by metallic bond, hence with the presence of the 'sea of electrons' , it is able to carry the current 5) Ca2+ and OH- hence ionic , in the OH-, they share electrons making it covalent 6) ozone have dative bonding but co2 doesn't have OO-OThe first Oxygen has 2 paired dots, 2nd has 2d paired dots, 3d has 3 paired dotsOne electron was donated by the 2d oxygen to the 3rd oxygenAs dor co2 oco 7) covalent ; made up of 2 non metalsAlso id u draw out the structure, they share electrons hence convalent 8) nitrogenN triple bond N while O double bond O (OO) hence more energy is require to break the triple bond than double bond, Bond energy N2 994kJ/mol, O2 496kJ/mol
