No. The sulfur oxygen bond is polar due to the electronegativity difference between S, EN 2.58, and O, EN 3.44. The molecule is bent and therefore the bond dipoles do not cancel and SO2 has a dipole moment of 1.62D
The CI bond is slightly polar due to the small electronegativty difference between C (EN 2.55)and I (EN 2.66). For example CH3I has a dipole moment of around1.62-1.64 D (different researchers have published different figures)
Molecules experience dipole moments due to the difference in electronegativities between two chemically bonded atoms. Carbon has an electronegative value or 2.55 and oxygen has a value of 3.44, the difference between the two is 0.89, meaning the oxygen atom pulls electrons towards itself and away from the carbon atom with a dipole moment of 0.89. Carbon dioxide has two oxygen opposite each other pulling electron density towards themselves with the same force but in opposite directions. The vectors, being equal in magnitude but opposite in direction, perfectly cancel each other out and leave the overall dipole moment of carbon dioxide to be 0. 3.44-2.55 C-----O p+ ---> p-

Br is one of those diatomic molecules that you'll have to remember. Br-Br is more stable than Br. If you mean bromine itself, then no, there is a 0 electronegativity difference. Dipole moments are, by rule of thumb, generally from EN differences of 0.4 to 2.0. Anything before 0.4 is considered nonpolar/covalent bonded and anything over 2.0 is considered ionic.

The question ¿Dónde estas en este momento? means "Where are you right now?" (Where are you at this moment?) The response depends on where you are. "I am at home" "Estoy en mi casa" "I am in my car" "Estoy en mi coche/auto/carro" "I am at the store" "Estoy en la tienda"
