Answer: The answer is D.
Explanation:
As the air rushes toward the center, it winds up moving in a curved path thanks to the Coriolis effect. This creates a circular spinning pattern as air travels from areas of high pressure to low pressure. That's why hurricanes originating in the northern hemisphere rotate counterclockwise.

Answer:
0,0,0,0
Explanation:
The formal charge formula:
So:
Hydrogen: 1 elec. of valence and shares two electrons with the O
Oxygen: 6 elec. of valence, 2 lone pairs and shares two electrons with the H and two with the F
Fluorine: 7 elec. of valence, 6 lone pairs and shares two electrons with the O
Oxygen: 6 elec. of valence, 3 lone pairs
Note: the dative bond between F and the second O doesn't count as shared electrons.
Answer:
use secondary data. the normal method to use
When you add salt to water, you lower to freezing point of the substance.
So for example, normal water freezes at 0°C. But water with salt in it won't freeze at 0°C, because its freezing point is lowered.
In answer to the question. It takes longer for water with salt in it to freeze because the substance requires a lower temperature than normal water to freeze.
Answer:
Physical change
Explanation:
The molecules are being rearranged as the water changes phases from liquid to gas, but this doesn't change the chemical structure of the water.
