What is the hydrophobic effect? what types of atoms are most likely to be found in portions of molecules or entire molecules tha
HACTEHA [7]
Hydrophobic in simple terms is the "fear" of water.

In chemistry, Ionic salts are technically hydrophilic as they will dissolve in water.
most fats and oils or triesters won't why?

salts are made from ions and their structure contain polar bonds Na+ and Cl-
Fats and oils tend to not have these.

Fats and oils contain many carbon covalent bonds which are non-polar which tend to make the molecule non-polar as a whole, therefore, it can't dissolve in water and is said to be hydrophobic.

Hope that heps :)
NB included a diagram to help.

oth hydrogen sulfide (H2S) and ammonia (NH3) have strong, unpleasant odors. Which gas has the higher effusion rate? If you opene
Ksju [112]

Answer: Odor of ammonia would we detect first on the other side of the room.

Explanation:

To calculate the rate of diffusion of gas, we use Graham's Law.

This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows:

\text{Rate of diffusion}\propto \frac{1}{\sqrt{\text{Molar mass of the gas}}}

\frac{Rate_{H_2S}}{Rate_{NH_3}}=\sqrt{\frac{M_{NH_3}}{M_{H_2S}}}

\frac{Rate_{H_2S}}{Rate_{NH_3}}=\sqrt{\frac{17.031}{34.1}}

\frac{Rate_{H_2S}}{Rate_{NH_3}}=0.71

Thus the odor of ammonia would we detect first on the other side of the room as the rate of effusion of ammonia would be faster as it has low molecular weight as compared to hydrogen sulphide.

100 points!! Brainliest if correct!!
Misha Larkins [42]

D has the fastest reaction rate because dynamite explodes almost immediately.

A isn't correct because rusting nails take forever to completely rust.

B isn't correct because logs burning can take around 10 to 20 minutes.

C isn't correct because food digestions takes anywhere between 10 minutes to an hour.
