Which of the following has the lowest entropy?

Chemistry
2 answers:
Bess [88]3 years ago
8 0

Answer: Option (B) is the correct answer.

Explanation:

Entropy is defined as the degree of disorder or randomness. This means that when particles of a matter move rapidly and continuously from one place to another then this shows entropy of the matter is high.

For example, particles of a gas are weakly held and hence, they rapidly collide and show high entropy.

Whereas in solids, particles are held together by strong intermolecular forces of attraction. Thus, they are not moving and hence in solids entropy is the lowest.

Thus, we can conclude that out of the given options, H_{2}O(s) has the lowest entropy.

I believe that the answer is B:  H2O(s) because is the makeup of water also known as one hydrogen and two oxygen. So water as more entropy and the s stands for sol fore i think wich means it contains the most entropy.

user100 [1]

Answer: Barium is +2, Fluorine is -1

Explanation:

The charge of barium is +2, and the charge of fluorine is -1. You can determine this from the periodic table groups.

The formula for barium fluoride is thus BaF2.

Four gases were combined in a gas cylinder with these partial pressures: 3.5 atm N2, 2.8 atm O2, 0.25 atm Ar, and 0.15 atm He.
Cerrena [4.2K]

Answer:

Answer :

The total pressure inside the cylinder is, 6.7 atm

The mole fraction of N_2 in the mixture is, 0.52

Solution :

First we have to calculate the total pressure inside the cylinder.

According to the Dalton's law, the total pressure of the gas is equal to the sum of the partial pressure of the mixture of gasses.

P_T=p_{N_2}+p_{O_2}+p_{Ar}+p_{He}

Now put all the given values is expression, we get the total pressure inside the cylinder.

P_T=3.5+2.8+0.25+0.15=6.7atm

Now we have to calculate the mole fraction of N_2 in the mixture.

Formula used :

pN_2=XN_2 x P_T

where,

P_T = total pressure = 6.7 atm

pN_2 = partial pressure of nitrogen gas = 3.5 atm

XN_2 = mole fraction of nitrogen gas = ?

Now put all the given values in the above formula, we get

3.5atm=XN_2 x 6.7atm

XN_2=0.52

Therefore, the total pressure inside the cylinder is, 6.7 atm and the mole fraction of N_2 in the mixture is, 0.52

Hope it helps answer the question:)
