What is the freezing point of an aqueous solution that boils at 105.0 ∘C? Express your answer using two significant figures.

Answers

The boiling point of standard water is 100 degree Celsius, with the addition of solute the boiling point is elevated. The freezing point of the solution will be -18.04 degree Celsius.

What is boiling point?

The boiling point is the temperature at which the liquid is converted to vapor. The change in boiling point of the aqueous solution gives the molality of the solution as:

$\rm \Delta T=ebuliloscopic constant\;*\;molality\;*\;von't\;hoff\;factor\n105^\circ C-100^\circ C=0.512^\circ C.kg/mol\;*\;1\;*\;m\n9.7\;mol/kg=m$

The depression in freezing point from molality is given as;

$\rm \Delta T=K_f\;*\;molality\;*\;i\n\Delta\;T=1.86\;^\circ C/m\;*\;9.7\;*\;1\n\Delta T=18.04\;^\circ C\n$

The freezing point of aqueous water is zero degree Celsius. The freezing point of the solution will be:

$\rm \Delta T=0^\circ\;C-New\;freezing\;point\n18.04^\circ\;C=0-New\;freezing\;point\nNew\;freezing\;point=-18.04^\circ C$

The freezing point of the solution is -18.04 degree Celsius.

Answer:

T°fussion of solution is -18°C

Explanation:

We have to involve two colligative properties to solve this. Let's imagine that the solute is non electrolytic, so i = 1

First of all, we apply boiling point elevation

ΔT = Kb . m . i

ΔT = Boiling T° of solution - Boiling T° of pure solvent

Kb = ebuliloscopic constant

105°C - 100° = 0.512 °C kg/mol . m . 1

5°C / 0.512 °C mol/kg = m

9.7 mol/kg = m

Now that we have the molality we can apply, the Freezing point depression.

ΔT = Kf . m . i

Kf = cryoscopic constant

0° - (T°fussion of solution) = 1.86 °C/m . 9.76 m . 1

- (1.86°C /m . 9.7 m) = T°fussion of solution

- 18°C = T°fussion of solution

what trend in the periodic table should be expected as the atomic number of the halogens increase from fluorine to iodine

Answers

Well one can expected many trends
1) Reactivity and Electronegativity decreases
2)Melting and Boiling point increases
3)There is an increase in colour intensity due to the progressive shift to longer wavelengths in the spectrum of light
4) The intramolecular attraction increase and as such there is a progressive shift from gas to solid
5)Increase in oxidising power
6) Atomic and ionic radii increases
7) Electrode potential decreases

What is kinetic energy? A. the energy an object has due to its motion B. the energy derived from chemical reactions C. the energy an object has due to its position D. the energy an object releases as heat

Answers

Answer: Option (a) is correct.

Explanation:

When an object moves from its initial position, it acquires some energy. This energy is called kinetic energy, as it is governed by the motion of an object.

The formula to calculate kinetic energy is as follows.

kinetic energy = $\frac {1}{2}mv^(2)$

where,

m = mass of object

v = velocity of object

Thus, it is concluded that kinetic energy is the energy an object has due to its motion.

The energy an object possesses due to its motion.

An Arrhenius base yields which ion as the only negative ion in an aqueous solution?(1) hydride ion (3) hydronium ion

Answers

An Arrhenius base yields hydroxide ion as the only negative ion in an aqueous solution.

What is an Arrhenius base?

This is defined as a substance which dissociates in water to form hydroxide (OH–) ions.

The hydroxide ion formed from the aqueoussolution is the only negative ion which is why option 4 was chosen.
