The volume did not change, it remained at 20 ml
Further explanationGiven
20 ml a sample gas at STP(273 K, 1 atm)
T₂=546 K
P₂=2 atm
Required
The volume
Solution
Combined gas Law :
[tex]\tt \dfrac{P_1.V_1}{T_1}=\dfrac{P_2.V_2}{T_2}[/tex]
Input the value :
[tex]\tt \dfrac{1\times 20}{273}=\dfrac{2\times V_2}{546}\\\\V_2=\dfrac{1\times 20\times 546}{273\times 2}\\\\V_2=20~ml[/tex]
The volume does not change because the pressure and temperature are increased by the same ratio as the initial conditions (to 2x)

Based on the image below, what is the displacement of the sound wave for Sound A + B at 0.1025 seconds?
A. -0.3316
B.0.3316
C.0.6255
D.1.6162
Answer:
The displacement of the sound wave for Sound A + B at 0.1025 is;
D. 1.6162
Explanation:
The sum of the displacement of two sound waves is given by the principle of superposition as follows;
y(x, t) = [tex]y_m[/tex]·sin(k·x - ω·t) + [tex]y_m[/tex]·sin(k·x - ω·t + ∅)
Therefore, by the property of the superposition of waves, the amplitudes of linear waves are added linearly when they meet at the same point at a the same time
The given parameters for the wave are;
The time at which the value of the wave amplitude are given, t = 0.1025 seconds
The displacement of the sound wave A at the given time, "t" is A = 0.9739
The displacement of the sound wave B at the given time "t" is B = 0.6423
Therefore, the displacement of the sound A + B = 0.9739 + 0.6423 = 1.6162

What is the ability for a substance to flow
The ability for a substance to flow is fluidity.
Which substances show flowing?Only liquid and gaseous substances have the ability to flow from one point to other as they have weak intermolecular force in it.
Fluidity is the quantity which gives idea about the ability of that substance to flow. At normal conditions at room temperature, any substance has the tendency to distort its shape in order to flow or take the shape of the container it is enclosed in.
Hence the ability for a substance to flow is fluidity.

When using the process of evaporation to separate a mixture, what is left behind
in the evaporating dish?
Answer:
When a solution is heated, the solvent evaporates, leaving behind the dissolved solids as residue. When a solution containing dissolved solutes is heated, the solvent will evaporate. Only the solute will remain in the evaporating dish.

When using the process of evaporation to separate a mixture, solute is left behind in the evaporating dish
What is evaporation?
Evaporation is a sort of vaporization that occurs on a liquid's surface when it transitions from a liquid to a gas.
Evaporation is a separation technique that can be used to separate components of a combination including a decomposed solid in a liquid. The liquid gets evaporated, which means it is converted from a liquid to a gas. This frequently necessitates the use of heat. The solid will be all that remains after the liquid has entirely evaporated.

The empirical formula : C₁₀H₂₀O
Further explanationGiven
Combustion of menthol
Required
The empirical formula
Solution
Mass of CO₂ produced : 0.449 g
mass C = 12/44 x 0.449 = 0.122
Mass water produced : 0.1840 g
Mass H = 2.1/18 x 0.1840 = 0.02
Mass O in menthol :
=mass sample - (mass C+mass H)
= 0.1595 - (0.122+0.02)
= 0.0175
Mol ratio C : H : O in sample :
= 0.122/12 : 0.02/1 : 0.0175/16
= 0.01 : 0.02 : 0.001
= 10 : 20 : 1
WILL GIVE BRAINIEST is C6H1005 + O2 → CO2 + H2O balanced?
Answer:
No! The balanced equation is given below:
C₆H₁₀O₅ + 6O₂ —> 6CO₂ + 5H₂O
Explanation:
C₆H₁₀O₅ + O₂ —> CO₂ + H₂O
The equation above is not balanced. It can be balance as illustrated below:
C₆H₁₀O₅ + O₂ —> CO₂ + H₂O
There are 6 atoms of C on the left side and 1 at the right side. It can be balance by 6 in front of CO₂ as illustrated below:
C₆H₁₀O₅ + O₂ —> 6CO₂ + H₂O
There are 10 atoms of H on the left side and 2 atoms on right side. It can be balance by 5 in front of H₂O as illustrated below:
C₆H₁₀O₅ + O₂ —> 6CO₂ + 5H₂O
There are a total of 7 atoms of O on the left side and a total of 17 atoms on the right side. It can be balance by 6 in front of O₂ as illustrated below:
C₆H₁₀O₅ + 6O₂ —> 6CO₂ + 5H₂O
Now, the equation is balanced.

Which of the following halogens has the weakest attraction for electrons?
I
F
Br
Cl
Answer:
I
Explanation:
Among the halogens given in this problem, iodine has the lowest attraction for electrons.
This property is known as electronegativity.
Electronegativity is expressed as the relative tendency with which the atoms of the element attracts valence electrons in a chemical bond.
As you go down the periodic group the electronegativity decreases. The most electronegative element on the periodic table is fluorine. Down the group, iodine is the least electronegativeThis is due to the large size of its atom.
