How would a solute affect the boiling point of water?

2 answers:

8 0

The answer is C. The water will boil at a higher temperature. This is because the solute is an impurity that raises the boiling point and lowers the melting point of water.

Answer: c.)

Explanation: A solute raises the boiling point of water. A solution with any solvent and non-volatile solute has a higher boiling point and a lower freezing point than the pure solvent. The amount by which the boiling point increases depends on the concentration of particles but not on the identity of the solute.

How do carbon-12 and carbon-13 differ?

Feliz [49]

Answer:

They have different amounts of neutrons.

They have different mass numbers.

Explanation:

Carbon-12 and carbon-13 are two isotopes of the element carbon. The difference between carbon-12 and carbon-13 is the number of neutrons in each atom. Atoms of both isotopes of carbon contain 6 protons. Atoms of carbon-12 have 6 neutrons, while atoms of carbon-13 contain 7 neutrons. And because the mass number is the sum of protons and neutrons in the nucleus then will be different too. Atoms of carbon-12 have the mass number equal to 12 a.m.u. while atoms of carbon-13 have the mass number equal to 13 a.m.u. .

a.m.u. - atomic mass units

If the concentration of fluoride anion and aluminum cation was increased to 5 m, by how much would the measured ecell change?.

ladessa [460]

If the concentration of fluoride anion and aluminum cation was increased to 5M, then there would be decrease in Ecell by 0.055 volts

The standard reduction potential of Fluoride anion and aluminum cation are -

2Al -----> 2Al3+ + 6e- $E^o$ cell = +1.66

6e- + 3F2 -----> 6F- $E^o$ cell = +2.87

The complete reaction is -

2Al + 3F2 ------> 2Al3+ + 6F- $E^o$ = +4.53

Using Nernst Equation :-

E = $E^o$ – 0.0592/n*log[Al3+]^2[F-]^6

n = 6 (n = number of transferred electrons)

E = +4.53 - 0.0592/6*log(5)^2(5)^6

E = +4.53 - 0.00987*log(25)(1.56 x 10^4)

E = +4.53 – 0.00987*log(3.9 x 10^5)

E = + 4.53 -0.00987(5.59)

E = + 4.53 - 0.055

E = +4.47

The change in Ecell = 5 - 4.47 = 0.055V
