Witch zone contains plenty of sunlight for photosynthesis
Answer:
well maybe it is open ocean (or the euphotic zone, witch is not an answer choice)
Explanation:
The top zone is the euphotic or sunlit zone. This is the ocean zone that sunlight penetrates. Because this zone gets sunlight, photosynthesis can occur and plants can grow here. The sunlit zone goes down to about 660 feet.

5. Element X has two isotopes: X-100 and X-104. If the atomic mass of X is 101
amu, what is the relative abundance of each isotope in nature?
Answer:
The abundance of X-100 is 75 percent, and X-104 has an abundance of 25 percent. The answers are found by solving two equations with two unknowns, which are A plus B equals 100, and 100A plus 104B equals 10,100.
The relative abundance of each isotope in nature
X-100 = 75%
X-104=25%
By dividing the total number of ions identified by the number of ions with a particular m/z m/z m/z ratio, one may determine the relative abundance for each individual ion in the sample.
How can the abundance of two isotopes be determined?
For chemistry problems involving relative abundance, use the following formula:
(M1)(x) + (M2)(1-x) = M (E)
Find the relative abundance of the isotopes if one nitrogen isotope, nitrogen-14, has a mass of 14.003 amu and another, nitrogen-15, has a mass of 15.000 amu.
Algebra can be used to find x. ...
x = 0.996

How does heat affect solubility of solids in a liquid?
A. The particles of a solid lose their shape and do not dissolve properly when heated
B. Solubility is not affected by heat.
C. Solubility generally decreases with heat.
D. Solubility generally increases with heat.
Answer:
Option D
Explanation:
Solubility is the amount of a substance in a solvent that dissolves at a specific temperature. So knowing this you would know that generally when you increase the temperature it also increases the solubility of a substance which means the answer is option D or "Solubility generally increases with heat."
Hope this helps.

3. Measure: Find the mass, volume, and density of each of the three crowns.
Mass (g)
Volume (cm)
Density (g/cm)
The volume of a bottle is 500cm. what is the volume of the bottle in millimeters
Answer:
5000mm
Explanation:
10mm makes 1 cm
so if we compare them:
10mm-->1cm
x -->500cm
now cross multiply:
1x-->5000
divide both sides by 1 for x to be alone
therefore we get x=5000
what kind of chemical processes are used to create these synthetic products
Aluminium is a natural material that is widely utilised in a variety of sectors and may be converted into a variety of synthetic goods via various chemical processes.
The following are some examples of synthetic compounds created from aluminium and the accompanying chemical processes:
Aluminium Foil: Aluminium foil is a thin, flexible sheet of metal.Aluminium Cans: Aluminium cans used for beverage packaging are created through a process known as can forming. Aluminium alloys are synthetic goods formed by mixing aluminium with additional elements such as copper, zinc, magnesium, or silicon.Thus, these are only a few examples of synthetic goods generated from aluminium and the chemical processes that produce them.

What is the density of a 500g box whose volume is 67 ml?
Answer:
7.46 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 500 g
volume = 67 mL
We have
[tex]density = \frac{500}{67} \\ = 7.462686[/tex]
We have the final answer as
7.46 g/mLHope this helps you

How many moles are there in 8.94*10^24 atoms P?
Answer:
14.85 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
[tex]n = \frac{8.94 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 14.850498[/tex]
We have the final answer as

Which statement describes what a thermos does?
A. A thermos makes things warmer
B. A thermos stops heat transfer
C. A thermos makes things cooler
D. A thermos slows heat transfer
A thermos slows down the process of heat transfer as it minimizes the process of conduction and convection.
What is conduction?
Conduction is defined as a process as a means of which heat is transferred from the hotter end of the body to it's cooler end.Heat flows spontaneously from a body which is hot to a body which is cold.
In the process of conduction,heat flow is within the body and through itself.In solids the conduction of heat is due to the vibrations and collisions of molecules while in liquids and gases it is due to the random motion of the molecules ,
When conduction takes place, heat is usually transferred from one molecule to another as they are in direct contact with each other.There are 2 types of conduction:1) steady state conduction 2) transient conduction.According to the type of energy conduction is of three types:
1) heat conduction
2) electrical conduction
3)sound conduction

How many moles of carbon atoms are there in
5g of carbon?
Answer:
12 atoms of carbon
Explanation:
(6.023X10^23)/12 atoms of Carbon.
There are 0.42 moles of carbon atoms in 5g of carbon.
HOW TO CALCULATE NUMBER OF MOLES:The number of moles in a substance can be calculated by dividing the mass of the substance by its molar mass. That is;no. of moles = mass (g) ÷ molar mass (g/mol)
According to this question, the mass of carbon is 5g. The molar mass of carbon is 12g/mol.No. of moles = 5g ÷ 12g/mol
No. of moles = 0.42moles
Therefore, there are 0.42 moles of carbon atoms in 5g of carbon.
