Answer:
1. Pollution caused the bark to become darker.
2. The light-colored peppered moth had a higher chance of survival
3. The dark-colored peppered moth had a higher chance of survival
4. During the Industrial Revolution, the barks of trees got darks, causing the moths to be seen easily on a dark background. Now predators were more likely to eat the lighter cloured moths as they were easier to find. Since fewer light-colored moths were surviving, there was a smaller likelihood of light moths surviving long enough to reproduce. Since there were fewer light-colored moths, the dark-colored moths had less competition and were able to reproduce quickly.
5. Sunny, warm place: I live in a place with lots of light and sunshine, so it would be easier for light moths to blend in with their environment long enough to reproduce and thrive.
Dark, rainy Place: I live in a place with little light and sunshine, so it would be easier for dark moths to blend in with their environment long enough to reproduce and thrive.

A). Ball A is repelled by Ball B ,
B). Ball B is attracted to Ball A ,
C). Ball B transfers energy to Ball A ,
D). Ball A transfers energy to Ball B
Answer:
C). Ball B transfers energy to Ball A
Explanation:
The motion of ball A is a because of the energy it acquires.
Ball A initially due to its position posses potential energy due to its position.
The moving ball B has kinetic energy due to the motion of this ball.
Due to the collision, momentum is transferred from the moving ball to the static one. As the momentum of the static ball changes, potential energy is converted to kinetic energy. The magnitude of the energy possessed by the static ball must be lesser than that of the moving.Answer:

Periodic table is divided into three metals, non metals and metalloids. The metals are kept on the left side of the periodic table. Gold is a metal which exist in d block.
What is metal ?
Metals are those elements which is hard, conduct electricity, ductile, lustrous and malleable.
The properties of gold are:
1.Gold have free electrons that's why they can conduct electricity
2. Since atoms in Gold are very closely packed in a definite crystal so gold is solid. It is not brittle that is it can not be broken down easily
3. Gold does not react with water easily.
4.Gold is denser than water hence it sink in water.
Gold is a transition element. Gold is found in d block of periodic table. Its symbol is Au.
Therefore, Gold is a metal which exist in d block.

What is the molarity of a HCl solution that
contains 6.27 g of HCl in 163 mL of solution?
Answer in units of M.
Answer:
M = 1.04 M
Explanation:
Given data:
Molarity of solution = ?
Mass of HCl = 6.27 g
Volume of solution = 163 mL (163 mL× 1L /1000 mL = 0.163 L)
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Number of moles of HCl:
Number of moles = mass/molar mass
Number of moles = 6.27 g / 36.5 g/mol
Number of moles = 0.17 mol

If the world suffered a huge catastrophic event (an event causing great and often sudden damage or suffering; a disaster) that wiped out almost all the organisms. Who would have the best chance of repopulation the world with living organisms, an asexual reproducing organism or a sexually reproducing organism? Explain your answer.
Answer:
An asexually reproducing organism would have the best chance of repopulating the world.
Explanation:
Sexual reproduction is a method of reproduction that involves two parents and the formation and subsequent fusion of male and female gametes during fertilization. On the other hand, In asexual reproduction, only one parent is involved and produces offspring by making copies of itself through various methods such as binary fusion, budding and vegetatively.
In a case of a catastrophic event that wiped out almost all organisms, an organism that reproduces asexually have a greater chance of repopulating the world because of the following advantages in reproducing asexually:
1. Only one parent is needed, therefore reproduction is easier.
2. It isaves time and energy. Since almost all organisms have been wiped out, there is a lesser likelihood of finding a compatible mate, so reproducing asexually will give the organism a better chance.
3. It occurs at a very fast rate; much faster than sexual reproduction
4. The population can increase very quickly and colonization of new habitats is much easier.
All these advantages will give the esexually reproducig organism a fairer chance to repopulate the world.

Using the diagram below and the labels attached to it answer the following:
Transverse Wave Anatomy
1. Define the crest and trough of a wave and identify TWO points that represents a crest or a trough.
2. Define wavelength and identify TWO points that could be used in the diagram to measure it.
2. Determine the frequency of this wave if the waves the diagram represents occurred within 1 second.
Answer & Explanation:
Crest is a point in the cycle where maximum or peak amplitude exists. In another way, it is a point on the positive side of a wave where maximum amplitude exits. Trough is a point in the cycle where minimum amplitude exists.
Crest: points A and E
Trough: points C and J
Wavelength is the distance between two crests or two troughs. One example is distance between points A and E.
Frequency is 3 because there are 3 oscillations in 1 second (follow the line from beginning to point D, then D to G, the G to end).
I asked that question on my brainly account to answer your question so the people that answerd my question said this is right I HOPE IT IS!!
1. The highest point or crest of a wave is called a crest, and the lowest point or valley is called a trough.
2. The wavelength of a wave is the distance between its two successive crests or troughs.
3. The frequency of a wave is the number of complete cycles (peak or trough) that occur in a unit time.
1. The highest point or crest of a wave is called a crest, and the lowest point or valley is called a trough. On the other hand, in a transverse wave, the peak and trough will be represented by the places of highest displacement above and lowest displacement below the equilibrium position, respectively.
2. The wavelength of a wave is the distance between its two successive crests or troughs. However, wavelength can be determined by comparing any two locations that are separated by a full circle, such as two successive crests or troughs.
3. The frequency of a wave is the number of complete cycles (peak or trough) that occur in a unit time. If the waves in the diagram are visible within one second, then the frequency will be determined by how many complete cycles were visible within that time.

1. The gases SO2, O2 and SO3 are allowed to reach equilibrium at a constant temperature. The equilibrium constant for the reaction
2SO2(g) + O2(g) -> 2S03(g)

a) Calculate the value of Kp for the reaction
SO2(g) + ½O2(g) -> SO3(g)
(b) The equilibrium constant for the dissociation of Pcl5(g) to form PCl3(g) and Cl2(g) is
0.04 at 250°C. An equilibrium mixture contains 0.20 mol PC13 and 0.12 mol Cl, in a
4000 cm container.

b)
[tex]PCl_5\rightarrow PCl_3+Cl_2[/tex]
[tex][PCl_5]=0.0375M[/tex]
Explanation:
Hello!
a) In this case, since we can see that the second reaction is equal to the half of the first reaction, we can relate the equilibrium constants as shown below:
[tex]K_2=K_1^{1/2}[/tex]
Thus, by plugging in the the equilibrium constant of the first reaction we obtain:
[tex]K_2=(1.6x10^4atm^{-1})^{1/2}\\\\K_2=1.3x10^{2}atm^{-1/2}[/tex]
b) In this case, for the described reaction we can write:
[tex]PCl_5\rightarrow PCl_3+Cl_2[/tex]
Thus, the corresponding equilibrium expression is:
[tex]K=\frac{[PCl_3][Cl_2]}{[PCl_5]}[/tex]
In such a way, since we know the equilibrium constant and the concentrations of PCl3 and Cl2 at equilibrium, we can compute the concentration of PCl5 at equilibrium as follows:
[tex][PCl_5]=\frac{[PCl_3][Cl_2]}{K}\\[/tex]
[tex][PCl_5]=\frac{\frac{0.20mol}{4L} *\frac{0.12mol}{4L} }{0.04}[/tex]
[tex][PCl_5]=0.0375M[/tex]

KClO3→ KCl+. O2
Answer:
2KClO₃ → 2KCl + 3O₂
Explanation:
The unbalanced expression is given as:
KClO₃ → KCl + O₂
The reaction equation above is unbalanced and we need to choose between the numbers 2,3,4 and 5 to finally the correct expression that will obey the law of conservation of mass.
aKClO₃ → bKCl + cO₂
Let a, b and c be the numbers that will balance the expression;
Conserving K;
a = b
Conserving Cl;
a = b
Conserving O;
3a = 2c
let a = 1, b = 1 and c = [tex]\frac{3}{2}[/tex] multiply through by 2;
a = 2, b = 2 and c = 3
So, the balance expression insert;
2KClO₃ → 2KCl + 3O₂
