Answer:

It is possible to separate several distinct compounds according to their varying volatilities by altering the temperature of the distillation process. A nonvolatile solute, on the other hand, will always remain in the solution if you have a nonvolatile solute in your solution.

Explanation:

Hope it helps:)

Answer:

The reason for this is that the composition of the vapor that is distilling varies continuously during the distillation

At the left side; the balanced half equation is:

[tex]\mathbf{2H_2O _{(l)} + 2e^- \to H_{2(g)} + 2OH^{-}_{(aq)}}[/tex]

At the right side, the balanced half equation is:

[tex]\mathbf{4OH^-_{(aq)} \to O_{2(g)} + 2H_2O_{(l)} + 4e^-}[/tex]

The objective of this question is to determine the balanced half-reaction for the electrodes on the left and the right side.

A half-reaction is an oxidation-reduction reaction part of a redox reaction where we make sure both half-reactions are balanced by multiplication of the reactions with appropriate numbers in order to have an equal number of electrons.

According to the given information:

The overall cell reaction can be expressed as:

[tex]\mathbf{H_2O_{(l)} \to H_{2(g)} + \dfrac{1}{2}O_{2(g)}}[/tex]

At the left side; the balanced half equation can be expressed as:

[tex]\mathbf{2H_2O _{(l)} + 2e^- \to H_{2(g)} + 2OH^{-}_{(aq)}}[/tex]

At the right side, the balanced half equation can be expressed as:

[tex]\mathbf{4OH^-_{(aq)} \to O_{2(g)} + 2H_2O_{(l)} + 4e^-}[/tex]

Answer:

A

Explanation:

As  per the concept of thermal energy, heat energy will be moved from hot water of canister to cold water of beaker as heat flows from point at high temperature to point at lower temperature.

Thermal energy is defined as a type of energy which is contained within a system which is responsible for temperature rise.Heat is a type of thermal energy.It is concerned with the first law of thermodynamics.

Thermal energy arises from friction and drag.It includes the internal energy or enthalpy of a body of matter and radiation.It is related to internal energy and heat .It arises when a substance whose molecules or atoms are vibrating faster.

These vibrating molecules and atoms collide and as a result of which heat is generated in a substance , more the collision of particles , higher is the thermal energy.

Pb[lead] [Xe]4f^145d^106s^26p^2

7s^2 5f^4

This notation can be written in core notation or noble gas notation by replacing the

1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^6 6s^2 4e^14 5d^10 6p^6

7s^2 5f^4

with the noble gas [Rn].

[Rn]7s25f4

N[nitrogen] The full electron configuration for nitrogen is 1s^2 2s^2 2p^3.

Ti[titanium] Ti2+:[Ar]3d^2

Ti:1s^2 2s^2 2p^6 3s^2 3p^6 3d^2 4s^2

1s^2 2s^2 2p^6 3s^2 3p^5 = 17 electrons

(1) electron gain will result to a

negative charge (−), and

(2) electron loss will result to a positive charge (+),

1s^2 2s^2 2p^6 3s^2 3p^6 = 18 electrons

Hg[mercury] You should then find its atomic number is 80. It has a Xe core, so in shorthand notation, you can include [Xe]instead of

1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 4p^6 4d^10 5s^2 5p^6,

for 54 electrons. For the 6th row of the periodic table, we introduce the 4f orbitals, and proceed to atoms having occupied 5d orbitals. We, as usual, have the ns orbitals, and n=? for the 6th period?

Mercury has a regular electron configuration. It becomes:

Enzymes are responsible for dictating what chemical changes happen and when, so thus they control the life process of the cells in our bodies.

The cell wall is what gives a plant cell it's distinct shape (animal cells don't have cell walls btw).

Intracellular fluid, or cytosol, is the fluids stored in the Intracellular compartment.

The cell membrane is the barrier between everything inside the cell, and everything else outside of it. It protects the contents of the cell from harm and releases toxins and other waste from it. The cell membrane is basically like the gate keeper of the cell.

Answer:

Explanation:

(winks and runs off)

Answer:

Exothermic

Explanation:

Combustion reactions are almost always exothermic because it is an oxidation reaction that produces heat and in this case it would be considered to be exothermic but there are few cases in which it would be considered endothermic. Combustion of Nitrogen is endothermic because Δ  is positive despite being a combustion reaction.

After beginning the experiment with a saturated solution, then increasing the heat, we will be left with an unsaturated solution.

To obtain the saturated solution, we must dissolve sugar in the water. We can say that the solution has become saturated when the solution is no longer able to dissolve more sugar. It has reached its capacity for the solute that it can dissolve in these conditions.

However, the temperature of a solution has an effect on the dissolving limit of the solution. That is, when a solution is heated it becomes able to dissolve more solute. Therefore, if we were to heat a saturated solution, it will be able to dissolve more solute and therefore will no longer be at its limit, meaning it is no longer a saturated solution. It has become unsaturated.
