SO2<span> molecule </span>have a dipole moment<span> and a </span>CO2<span> molecule doesn't ... </span>Dipole moment<span> of </span>CO2<span> molecule </span>is zero<span>,becoz it is linear molecule,whereas </span>SO2<span> is angular</span>
How am I supposed to know >:(
Gas is the most compressible because the atoms have more space in between. solids on the other hand, are the least compressible because their atoms are really closely packed.
<span>Chemical transformation: it's all transformation changes the composition of matter, i.e. that matter produces a new substance with different initial properties burning sugar to make caramel, we cannot retrieve the initial sugar.

hope this helps!
Answer:
C) Covalent bonds come about because of a sharing of electrons; ionic bonds do not.
Explanation:
There are two main types of chemical bonds- covalent and ionic/electrovalent bonds.
Ionic bond: Ionic or electrovalent bonds are characterized by the transfer of electrons from electropositive atoms (metals) to electronegative atoms (non-metals). The metal atoms after donating their electrons become positively charged ions (cations) while the non-metal atoms after accepting electrons become negatively charged ions (anions). Strong electrostatic forces of attraction constitutes ionic bonds.
Covalent bond: Covalent bonds are formed by the sharing of electrons by the atoms involved in the bond; usually between atoms of comparable electronegativities or atoms of the same element. The shared electrons are contributed by each of the atoms involved in the bonding or may be contributed by only one of the atoms. In covalent bonding, molecules rather than ions are formed.
