Your question isn't quite clear, but if you're wondering if a chemical is polar or non-polar, you simply draw a VSEPR sketch and draw arrows where the bonds are. Only draw arrows between atoms, NOT between an atom and a lone pair of electrons. The arrow should point to the most electronegative atom (you should be given an electronegativity scale). Afterwards, you add up the arrows as vectors, and look at the sum of the vectors. If the sum is zero (CH4 is a good example), the chemical is non-polar. If the sum is a vector, the chemical is polar (H2O, or water, is polar).

Answer:“If we’ve covered all of the potential sources, and we know the unique signature of the sand from these different sources, and we find it on a beach somewhere, then we basically know where it came from,” explained Barnard.
Explanation:
The formula that shows the correct representation of the combined gas law is; V1P1 / T1=V2P2 / T2
The combined gas law is obtained from the statements of Charles law and Boyle's law as follows;
Charles law; V/T = k
Boyle's law = PV = k
Combining the two I have; PV/T = k
For two masses of an ideal gas;
V1P1 / T1=V2P2 / T2
This is the statement of the combined gas law.
