Answer: Gravity depends on two main factors.
Explanation: Those factors are mass and distance. I hope this helps!
Answer:
Propyne can be converted to the acetone when it is made to undergo the reaction with mercuric sulphate followed by hydrolysis and thus, resultant product, thus formed is acetone.
Explanation:
When it comes to physical changes like phase changes, there are two types of heat energy: sensible heat and latent heat. Sensible heat is the heat absorbed/released when you heat the substance but it doesn't change phase. An example would be heating lukewarm water. The substance is liquid all throughout. Latent heat, on the other hand, is the heat absorbed/released when there is a phase change. An example would be boiling water, because it changes liquid to vapor.
Hence, for freezing liquid, you use the latent heat, specifically the heat of fusion. The answer should be
2.5 g * (1 mol/18.02 g) * 6.03 kJ/mol = 0.84 kJ/mol
The answer is not in the choices. You only use Hvap if you boil water.
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.
Hope this helps!
