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.

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
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

The relative atomic mass of element A : 6.075 u
Further explanationThe elements in nature have several types of isotopes
Isotopes are atoms whose no-atom has the same number of protons while still having a different number of neutrons.
So Isotopes are elements that have the same Atomic Number (Proton)
Atomic mass is the average atomic mass of all its isotopes
Mass atom X = mass isotope 1 . % + mass isotope 2.% ...
Element A
mass number of isotope 1 = 6 , percent : 92.5%
mass number of isotope 2 = 7, percent : 7.5
Relative atomic mass of element A
[tex]\tt = 92.5\%\times 6+7.5\%\times 7\\\\=5.55+0.525=6.075~u[/tex]

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

8n-3y = 18 and5x+6y=27
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

Answer:
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.

Which terms represents the fixed proportion of elements in a compound
Answer:
Protons
Explanation:
I'm not exactly sure if this is what your question, but the number of protons is what makes an atom that atom. If you change the number of proton it is now a different atom. You change the number of electrons and get an ion or change the number of neutrons and get an isotope but you can't change the number of protons as you would be changing the elemnt.

Write the chemical symbols for three different atoms or atomic cations with 26 electrons.
The chemical symbols for three different atoms or atomic cations with 26 electrons are Fe, [tex]Co^+[/tex], [tex]Ni^{2+}[/tex]
Explanation:
The atomic number of an atom is equal to the number of protonsAn atom is neutral, it has an equal number of electrons and protons.Element with atomic number 26 is Iron, Fe.A neutral atom of iron has an equal number of protons and electrons.Cobalt has an atomic number of 27.A neutral atom of cobalt has an equal number of protons and electrons.Cobalt has 27 electrons and by losing one electron it will form a cobalt (I) ion with 26 electrons.The cobalt (I) ion has 26 electrons, [tex]Co^+[/tex].Nickel has an atomic number of 28.A neutral atom of nickel has an equal number of protons and electrons.Nickel has 28 electrons and by losing two electrons it will form a nickel(II) ion with 26 electrons.The nickel (II) ion has 26 electrons,[tex]Ni^{2+}[/tex].So, from this, we can write chemical symbols for three different atoms or atomic cations with 26 electrons are Fe, [tex]Co^+[/tex], [tex]Ni^{2+}[/tex].
