The mixture can be separated into three separate components by using a centrifuge and a separating funnel.

A centrifuge is used to separate a solid that is held in suspension by a liquid. In this case a solid dissolved in water. In contrast, a separating funnel is used to separate two immiscible liquids.

-First take the flask containing the two immiscible liquids and pour contents in to a closed separating funnel.

- The most dense liquid will settle at the bottom, then open the separating funnel valve to collect contents of dense liquid into a flask.

- The remaining liquid on the separating funnel can be collected in a different flask.

-Now take the liquid that is a solution of a solid in water and pour in a test tube. Place the contents in a centrifuge.

- Centrifuge at high speed until the solid sinks to the bottom of the test tube, then decant the liquid into a flask and the solid remains in the test tube

Answer:

It can be separated using a separating funnel followed by crystallization.

Explanation:

First the mixture is put into a separating funnel. This will separate the two immiscible liquids. When the two immiscible liquids are separated, we recall that one is a solution of a solid solute and we wish to recover the solid from the solution whilst recovering the solvent also.

The solid can only be recovered by crystalization if we do not want to loose the solvent. Seeds of already crystalized solute may be added to system to induce crystalization.

Answer:

<u>True</u>

Explanation:

|ndeed,  Psychologist Abraham Maslow's sought to describe hierarchy in which the average (or most) humans place their needs. In other words, he believes we as humans have basic needs which we long to satisfy.

On the ranking or hierarchy, according to Maslow the need humans satisfy first is their physiological need. Here's the full hierarchy:

Physiological Needs

↓

Safety Needs

↓

Love/Belonging Needs

olga2289 [7]

Answer:

The correct answer is "True".

Explanation:

A reaction mechanism is a theoretical postulate that tries to explain in a logical way which are the elemental and intermediary reactions that happen in a chemical reaction and that allow to explain the qualitative and quantitative characteristics observed in its development, in which a unique molecular event is described in each elemental step.

Which of the following statements about electronic configurations of atoms and mononuclear ions, and atomic orbital quantum numb
ruslelena [56]

Answer:

a. The electronic configuration of the hydride anion is 1s2. TRUE

b. The valence electronic configuration of strontium is 4d2.  FALSE

c. For a given value of l the number of possible values of ml is 2l + 1.  TRUE

d. Cu+ has the same electronic configuration as Ni.  TRUE

e. The magnetic quantum number is never larger than the principle quantum number (for a given orbital). TRUE

Explanation:

a. The electronic configuration of the hydride anion is 1s² is true since the hydriden anion is the hdrogen atom which has gained an electron and we will add that electron to the 1s¹ configuration of H.

b. The valence electronic configuration of strontium is 4d2 is false since Sr is an element of period 5 , therefore its valece electrons are in in period five and it has 2 electrons because Sr belongs to group 2.

c. For a given value of l the number of possible values of ml is 2l+1 is true since this number gives the magnetic orientation for the sublevel. Thus for s there is only one orientation, then ml = 2 (0 ) +1 . Por p with  l equal to 1 we have three possible orientations : 2(1) + 1 =3. The d and f sublevels have 10 and 14 orientations.

d. Cu⁺ has the the same electronic configuration as Ni is true since Cu, atomic number 29, has one more electron than its neighbor Ni with an atomic number of 28. If we remove one electron from copper we are gong to have the same 28 electrons niquel has in its neutral state.

e. The magnetic quantum number is never larger than the principal quantum  number for a given orbital is true since l, the magnetic quantum number can have values up to n-1, the principal quantum number.
