Small drops of water are produced on the inside of the top cup because of the evaporated water from the hot water in the bottom cup and then condensed inside of the top cup. Condensation actually happens one of two ways, it is either the air is chilled to its dew point or when it becomes very saturated with water vapor that it could not hold any more water. Furthermore, condensation could also create water droplets on the outside of glasses of cold drinks or soda cans. When warm air reaches the cold surface, it gets to its dew point then it condenses. This is why there will be droplets of water on the can or glass.
Answer:
ν = 1483.939 m/s
Explanation:
Wave propagation speed (ν):
∴ Wavelength ( λ ) = 4.25 m
∴ Period ( T ) = 1 / f
∴ frequency ( f ) = 349.2 Hz ( s-1 )
⇒ T = 1 / 349.2 s-1
⇒ T = 2.864 E-3 s
⇒ ν = (4.25 m) / (2.864 E-3 s)
⇒ ν = 1483.939 m/s

Answer:
See explanation below
Explanation:
This reaction is known as the Grignard reaction. If's often used to add an alkyl to a molecule, in this case, a ketone. This also helps to reduce the carbonile to an alcohol.
The mechanism is taking place in 3 steps.
The first step involves the attack of the pair of electrons of the oxygen from the cyclohexanone to the MgBr, and the other pair takes the propyl.
The second step involves the breaking of this bond to have the OMgBr and the propyl attached to the carbon of the chain.
The last steps involves an hydration of the molecule, to turn the OMgBr into OH, and that would be the final product.
In this case, the final product will be 1-propyl-cyclohexanol.
The picture below, shows the mechanism and the drawing of the final product.
