One way to separate the different kinds of matter in a mixture is through


A. filteration
B. decomposition
C. electrolysis
D. chemical reactions

Answers

Answer 1
The answer is filtration (A).

Creating a mixture is a physical process; as such, the substances that make up a true mixture do not undergo any chemical reactions with one another. It follows, then, that to separate substances that are mixed together, the process to use would be physical, not chemical. Filtration fits that bill: Solutes that do not dissolve in the solvent can be trapped, for example, by a fine mesh whose openings are large enough for the solvent to pass through but too small for the undissolved solute(s) to do so.

Choices B, C, and D are all chemical processes.

Decomposition (B) is the breakdown of a substance into chemically distinct fragments. For example, hydrogen peroxide in a mixture (solution) with water decomposes in the presence of an appropriate catalyst—the products you are left with are water and oxygen gas, which bubbles out of the mixture. But you haven’t separated the hydrogen peroxide from the water—through decomposition, the hydrogen peroxide molecules are broken up and the atoms rearranged to form different molecules. There’s no hydrogen peroxide left to separate anymore. So, decomposition doesn’t separate different substances in a mixture—it transforms them.

Electrolysis (C) is a chemical process that uses an electric current to drive the movement of charged particles (electrons and ions) through a conductive medium. Suffice it to say that this will almost certainly change the chemistry of a mixture. For example, assume you’ve got a mixture of some inert, insoluble solute in water. If you run a very strong electric current through water, you’ll end up decomposing the water molecules themselves into oxygen and hydrogen gases. Again, you haven’t technically separated the solute from the mixture because separation implies that you have the separated substances still around. In this example, you’ve “separated” your solute by chemically transforming your solvent into two different gases; one part of your mixture no longer exists. (Side note: electrolysis of pure water takes quite a bit of energy; on the other hand, tap water, which contains dissolved electrolytes, can be readily decomposed via electrolysis using the current delivered by a standard alkaline battery.)

As a rule of thumb, the suffix (–lysis) usually indicates chemical decomposition, and the stem that precedes the suffix usually indicates what the decomposition process involves. Examples include electrolysis (as we just discussed), hydrolysis (breaking a chemical bond using water), glycolysis (the biochemical process of breaking down glucose into smaller molecules to harness the energy released), and radiolysis (splitting a bond within atoms comprising a molecule using ionizing radiation).

Finally, as should be clear by this point, chemical reactions are not the way to go about separating mixtures. Again, the chemical substances in a mixture retain their chemical identities. Separating the constituents of a mixture essentially entails isolating these substances. Filtration can and does isolate solutes from solvents without altering their chemical identities (assuming the filter itself is chemically inert). A chemical reaction changes a substances chemical identity, and so could not properly be regarded as a method of separation, and only separation.
Answer 2

One way to separate the different kinds of matter in a mixture is through filtration. The correct option is A.

What is filtration?

Filtration is a physical or mechanical process by which two or more substances are of different compositions. These substances can be solid, liquid, or gas.

There are three types of filtration. These are mechanical, chemical, and biological. The different types of filtration are based on a similar principle, which is a mixture of several types poured onto a filter membrane. A specific size of the pore is present in the filter membrane.

The other options are decomposition, which is a process of breaking down substances. Electrolysis is separating charged ions and chemical reactions to form compounds.

Thus, the correct option is A. filtration.

equatinal by elimination melha
8n-3y = 18 and5x+6y=27

Answers

Answer:

x = 3 and y= 2

Explanation:

Given equations:

           8x - 3y  = 18  - ---- (I)

           5x + 6y = 27 -------(II)

Solve this problem by elimination;

  In the elimination method, we simply find a common term that can make one of the variables in the two equation the same. Then we either add or subtract to remove the variable.

 Mulitply equation (i) by 5 to give equation III

 Mulitply equation (II) by 8 to give equation IV

     5(8x - 3y) = 5(18) ------- III

     8(5x + 6y) = 8(27) ------- IV

   40x - 15y = 90------- III

   40x + 48y = 216  ------- IV

Subtract  equation III and IV;

        -15y - 48y = 90 - 216

         - 63y = -126

                y = 2

Solve for x;

      40x - 15y = 90;

       40x - 15(2) = 90

         40x - 30 = 90

           40x = 90 + 30

              40x = 120

                 x = 3

At the end of meiosis, there are four cells, each with 23 chromosomes, for a total of 92 chromosomes split between the four cells.

Explanation:

During meiosis, a diploid cell  (46 chromosomes) replicates its DNA (making 92 chromosomes) then undergoes two cell divisions to generate four haploid cells (23 chromosomes).

These haploid cells are the gametes which, during fertilization, fuse to become a zygote with 46 chromosomes.

A 10.04-g block of solid tin at 14.77 °C is immersed in a 24.11-g pool of liquid ethylene glycol with a temperature of 63.52 °C. When thermal equilibrium is reached, what is the temperature of the tin and ethylene glycol? Specific heat capacities: tin = 0.213 J/g °C; ethylene glycol = 2.36 J/g °C

Answers

Answer:

61.75 °C

Explanation:

According to the law of conservation of energy,

Qtin = - (Qliquid)

(m×c×∆T)tin = -(m×c×∆T) ethylene glycol

Where; m = mass

c = specific heat capacity

∆T = change in temperature

According to the information given in this question;

For tin: m= 10.04g, c= 0.213 J/g °C, initial temperature= 14.77 °C, final temperature=?

For ethylene glycol: m= 24.11g, c= 2.36 J/g °C, initial temperature= 63.52 °C, final temperature=?

Hence; (m×c×∆T)tin = -(m×c×∆T) ethylene glycol

10.04 × 0.213 × (T - 14.77) = - {24.11 × 2.36 × (T - 63.52)}

2.139 (T - 14.77) = - {56.899 (T - 63.52)}

2.139T - 31.59 = -56.899T + 3614.225

2.139T + 56.899T = 31.59 + 3614.225

59.038T = 3645.815

T = 3645.815/59.038

T = 61.75 °C

The final temperature of tin and ethylene glycol is 61.75 °C

Describe what will happen to the pressure of the gas as the plunger is pushed in.

Answers

Answer:

The pressure of gas will increase.

Explanation:

The question above is related to "Boyle's Law." According to this law, provided that the temperature and amount of gas are stable, the absolute pressure of gas is inversely proportional to its volume.

In this sense, if the plunger will be pushed in, the volume of the gas will definitely decrease due to lack of space while the pressure will increase because the molecules of the gas are colliding with each other. The greater the collision, the greater the pressure. This explains the answer above.
