You are a forensic scientist and have been asked to identify a white, unlabeled powder recovered from the scene of a crime. as a first step, you're interested in learning if the compound is polar or non-polar. what should you do and how should you interpret your findings?

Answer and Explanation:

What one can do is to try dissolving the  powder in ; if the powder fails to get dissolved, then we can state that it is a non polar compound.  Non-polar compounds are known as or referred to as the compounds which tends to not have the slightly positive and negative charges within the given compound. Electronegativity differences of these  compounds are mostly in between 0 and 0.2.

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.
