Calculations in chemistry can range from large numbers to the smallest number in decimals to be more accurate in data results. When this occurs using scientific notations allows you to note down results regardless of size as accurate as possible without writing a lot of numbers.
Answer:
Polarity is a measure of molecule's electrical charge which means that molecule or it's groups can have a dipole moment and also make hydrogen bonds.
Explanation:
So in terms of polarity methanol is more polar then ethyl acetate due to it's higher dipole moment and that it is a stronger hydrogen bond acceptor and also can be a hydrogen bond donor. So if we add methanol to the elutioning system it becomes more polar because and our compound moves faster on tlc due to methanol providing some more hydrogen bonds to it and increasing dipole-dipole interactions.
Answer:
Predict the glaciers' locations.
Explanation:
You must research each glacier, and where it is now. Then try to figure out where it will go. Glaciers can go either forward or backwards, but they move in patterns. Predict!
Answer:
a), b), c) & f)
Explanation:
d) does not apply because Ms value can be either +½ or -½
e) does not apply because Ml - values range from -l to +l, hence l= 2 doesn't exist when l= 1
