When you look at the absorption spectra of cranberry juice and apple juice, what colors/parts of the visible spectrum are absorbed?
Discuss how the colors/parts that are not absorbed contribute to the colors of cranberry juice and apple juice.
Looking at the absorption Spectra of cranberry juice and apple juice the color and part of the visible spectrum that are absorbed as well as how the colors that are not absorbed contributed to the the colors of the cranberry juice and apple juice are;
When the light actually hits on a surface,it is only a part of it that is reflected to the eyes whereas the rest of the spectrum is then absorbed by the object.
However,if the red wavelength is reflected,you will see the red color,but if all the spectrums are absorbed,you will see the black color,if then all the spectrums is reflected,you will see the white color.
When the light hits the surface, just a part will be reflected in the eyes of the person.
From the complete information, when an individual looks at the absorption spectra of cranberry juice and apple juice, just a part will be seen.
When the light hits the surface, there'll be a reflection in the eyes of the person as just a part will be reflected. The rest of the spectrum will be absorbed by the object.
Also, if the red wavelength is reflected, then one will see the red color. When all the spectrum is absorbed, one will see the black color. Lastly, when all the spectrum is reflected, one will see the white color.

and 11 electrons.
2. All sodium atoms have the atomic number
11.
3. All sodium atoms have the same number
of protons.
4. All sodium atoms have 11 neutrons.
5. All atoms with atomic number 11 are
sodium atoms.
Answer:
1 is not correct ......
All neutral sodium atoms have 11 protons and 11 electrons is about sodium atoms (Na) is not correct. Therefore, option 1 is correct.
Which are neutral atoms?When an atom has the same number of electrons and protons, it has the same number of negative (electrons) and positive (protons) electric charges (the protons).
As a result, the total electric charge of the atom is zero, and it is said to be neutral. As a result, all elements in the periodic table have neutral atoms.
The sodium atom contains 11 electrons. As sodium atom loses one electron to form sodium ion, sodium ion has ten electrons. Only sodium atoms have a strong reaction with water, whereas sodium ions do not.
Thus, All neutral sodium atoms have 11 protons and 11 electrons is about sodium atoms (Na) is not correct, option 1 is correct.

30.5 g of sodium metal reacts with chlorine gas to produce sodium chloride. How much (in grams) chlorine gas must react with this amount of sodium
Answer:
Mass of chlorine = 47.22 g
Explanation:
Given data:
Mass of sodium = 30.5 g
Mass of chlorine= ?
Solution:
Chemical equation:
2Na + Cl₂ → 2NaCl
Number of moles of Na:
Number of moles = mass/molar mass
Number of moles = 30.5g/ 23 g/mol
Number of moles = 1.33 mol
Now we will compare the moles of Cl ₂ with Na from balance chemical equation.
Na : Cl ₂
2 : 1
1.33 : 1/2×1.33 = 0.665 mol
Mass of chlorine gas:
Mass = number of moles × molar mass
Mass = 0.665 mol × 71 g/mol
Mass = 47.22 g

0.817 grams of an unknown gas occupies 1.25 L at 27.0 C and a pressure of 765
mm Hg. Is the gas most likely methane (CH 4 ), ethane (C 2 H 6 ), propane or butane?
Show work to support your answer.
The gas is most likely methane (CH₄)
Further explanationIn general, the gas equation can be written
[tex]\large{\boxed{\bold{PV=nRT}}}[/tex]
where
P = pressure, atm
V = volume, liter
n = number of moles
R = gas constant = 0.08205 l.atm / mol K
T = temperature, Kelvin
[tex]\tt PV=\dfrac{mass}{M}RT\\\\M=\dfrac{mRT}{PV}=\dfrac{0.817\times 0.082\times 300}{1,00658\times 1.25}=15.97\approx=16[/tex]
So the gas is most likely methane (CH₄ )

Small frogs living in a marshy region feed on small insects in the region. The relationship between the frogs and insects is a relationship. A particular species of lizards is introduced into the marshy land. These lizards also start feeding on these insects. The introduction of lizards may lead to .
Answer:
The indroduction of lizards in this marshy habitat may lead to severe alterations of its own ecosystem. Since the lizards and frogs are both species who feed on small insects, the insect population might begin to decrease around the area. Furthermore, if insects have lessened in the marsh, that means food for the lizard as well as for the frog. In an extreme scenario, unless the two species adapt to these new conditions, their population may rapidly decrease.

Small frogs living in a marshy region feed on small insects in the region. The relationship between the frogs and insects is a commensal-host relationship. A particular species of lizards is introduced into the marshy land. These lizards also start feeding on these insects.

What is the volume of 902.0 g of C₂H₄ gas at STP
Answer:
Volume = 722.1 L
Explanation:
Given data:
Mass of gas = 902.0 g
Temperature = standard = 273.15 K
Pressure = standard = 1 atm
Volume of gas = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will calculate the number of moles of C₂H₄.
Number of moles = mass/molar mass
Number of moles = 902.0 g/ 28.05 g/mol
Number of moles = 32.2 mol
Volume of gas:
PV = nRT
1 atm ×V = 32.2 mol × 0.0821 atm.L/ mol.K × 273.15 K
V = 722.1 atm.L/1 atm
V = 722.1 L

Because of its size, adult blue whale has few natural predators. It’s diet consists exclusively of tiny creatures called krill. These whales can dive to great depths but must come to the surface regularly for air. From this information, what is one limiting factor for population of blue whales?
A. Availability of krill
B. Available sunlight for photosynthesis
C. Oxygen in water
D. Salinity of water
E. Visibility in water
Answer:
A
Explanation:
The correct answer would be the availability of krill.
A limiting factor is a substance or condition whose presence/absence can prevent a population from reaching its potential. Limiting factors can be biotic (living) or abiotic (non-living). Biotic factor includes the presence of competitive organisms in a population while abiotic factor includes food.
In the case of the blue whale, its diet is krill. Hence, its survival is largely dependent on the availability of krill. Otherwise, the blue whale might starve. Therefore, the availability of krill is a limiting factor for the population of whales.
The correct option is A.

13. Which are the simplest pure substances that cannot be broken down into any other substances?
Answer:
Elements
Explanation:
Each kind of atom is an element. Elements are pure substances that cannot be broken down into simpler substances by ordinary chemical means.
Answer:
Elements
Explanation:
Elements such as those on the periodic table are unable to be broken down into simpler forms.
Mixtures (both homogenous and heterogenous) are made of multiple elements making it able to be physically broken down back to its original elements.
Compounds are also made up of multiple elements, however it must go through a chemical separation process in order for it to be broken down into its original elements.
Matter is a broad term of any substance. So it could both be a combination or a single element making it incorrect for this question.

Which of the following quantum numbers describes a d-orbital in the fourth energy level?
a. n = 4, l = 0, m = 0
b. n = 3, l = 1, m = 0
c. n = 3, l = -1, m = 0
d. n = 4, l = 2, m = 0
Answer:
d. n = 4, l = 2, m = 0
Explanation:
A d-orbital in the fourth energy level can only be represented by n = 4, l = 2, m = 0.
n is the principal quantum number(n) which signifies the energy level, here it is 4;
l is the azimuthal quantum number or l which signifies the shape of the subshell, it takes a value of n - 1, 0,1,2 or 3
m is the magnetic quantum number(m) which can be -2, -1, 0, 1 , 2
So, the right and fitting solution is n = 4, l = 2, m = 0
