Molecular substances can have both polar and nonpolar covalent bonds.
From the given compounds, only sulfur dioxide has polar covalent bonds. Chlorine and nitrogen have non polar covalent bonds where calcium oxide is ionic.
yes
No. CaO is an ionic compound.
In most cases, covalent bonds are usually weaker, but there are exceptions such as diamond and graphite.
CaO because Ca is a metal and O is a gas and all the other possibillities are gasses combined and ionic has a metal and gas combination if you look at the periodic table of elements the right side is gases but they are determined by like a staircase and the rest are metals
CaO is ionic as the electronegativity difference between the two atoms is above 1.7
SO3
yes
No. CaO is an ionic compound.
H2O has a stronger bond then CaO because H2O is a covalent compound (made up of two nonmetals), whereas CaO is an ionic compound (made up of both a metal and nonmetal), and covalent bonds are stronger then ionic bonds.
In most cases, covalent bonds are usually weaker, but there are exceptions such as diamond and graphite.

Its ionic which means it's polar. All ionic solutes only dissolve in polar solvents.
CaO is ionic as the electronegativity difference between the two atoms is above 1.7
Calcium oxide
Calcium chloride is a compound between a metal and nonmetal. The difference in electronegativity between these elements is great. Therefore, CaCl2 is an ionic compound with ionic bonds
Na2SO4 and NaCl
Calcium oxide: CaCO3------CaO + CO2
