Prevailing winds bring air from one type of climate to another. For example, warm winds that travel over water tend to collect moisture as they travel; the water vapor in the air will condense as it moves into colder climates, which is why temperate coastal areas often receive heavy rainfall.

Is it possible for two different compounds to be made from the exact same two elements? Why or why not? With a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds or do we have a large number of compounds in this world?
PLEASE HELP ASAP
Thank you!!
Answer:
Yes. The two elements can combine to form different compounds.
Explanation:
Two elements can combine at different ratios.
Consider CO and CO₂. Both are made from carbon and oxygen. However, C and O combine at a 1:1 ratio in CO but at a 1:2 ratio in CO₂. CO is a fuel; it burns in the air. CO₂ does not burn in the air; it is used to put out fires and is found in extinguishers. CO and CO₂ are two distinct compounds.
There are many ways for the elements to combine with each other. As a result, the first twenty elements on the periodic table alone can produce a large number of compounds.

Answer:
the color change
Ples help is it Fission, Fusion, or Both 1. Incredibly high amounts of energy are released. ____ 2. Results in a nuclear change. ______ 3. The end product is heavier. _____ 4. Two nuclei become one. ____ 5. The end product is lighter. ____
Answer:
1. fission
2. both
3. fusion
4. fusion
5. fission
Explanation:
Fission refers to the splitting of a single nucleus into two or more small nuclei while fusion refers to the combination of two or more small nuclei into one heavy nucleus.
When a single heavy nucleus splits, energy is released and the end products are 2 or more lighter nuclei. On the other hand, when several light nuclei fuse into one nucleus, energy is absorbed and the end product is one heavy nucleus. Both fission and fusion result in a nuclear change.

What are the atoms found at the bottom of the periodic table known as?
The size of an atom would be described in _______.
Answer:
atomic radius
Explanation:
so radius
Answer:
Explanation:
The average size of an atom is about 100 picometers or one ten-billionth of a meter. Almost all of the mass of an atom is in its nucleus; almost all of the volume of an atom is occupied by electrons. The number of protons (also known as its atomic number) determines the element. Varying the number of neutrons results in isotopes.
Need help. Is this correct
Answer:
Yes, that is correct!
Explanation:
Answer:
Yes
Explanation:
A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.

What do you think causes a lunar eclipse? (Use your knowledge of solar eclipses and feel free to run the Gizmo to help you.)
Moon reflects the light frim the sun, thats why we are able to see it and it shines in the night. But, we know that Earth revolves around Sun and Moon revolves around Earth. During this revolution, Earth and Moon comes in a position when Earth is in the middle of the Moon and Sun. So, it blocks the light of Sun frim reaching Moon. Hence, we see no reflection and it causes Lunar eclipse.
Answer:
A total lunar eclipse occurs when the moon and the sun are on exact opposite sides of Earth. Although the moon is in Earth's shadow, some sunlight reaches the moon. The sunlight passes through Earth's atmosphere, which causes Earth's atmosphere to filter out most of the blue light.
Explanation:
A coffee cup calorimeter contains 153.21 g of water at 22.50 °C. A 65.454 g piece of iron is heated to 101.62 °C. The piece of iron is added to the coffee cup caloriemter and the contents reach thermal equilibrium at 25.68 °C. The specific heat capacity of iron is 0.449 Jg·K and the specific heat capacity of water is 4.184 Jg·K. How much heat, , is lost by the piece of iron?
Answer:
Q = 2232J
Explanation:
In the system, the energy that is lost by the iron is:
Q = S*ΔT*m
Where Q is heat, S is specific heat of iron ΔT is change in temperature and m is mass of the piece of iron.
S = 0.449J/gK
ΔT = 101.62°C - 25.68°C = 75.94°C
m = 65.454g
Q = 0.449J/gK*75.94°C*65.454g
Q = 2232J

Substance 2 has a stronger molecular attraction.
What are solids?Solid is one of the four fundamental states of matter. The molecules in a solid are closely packed together and contain the least amount of kinetic energy. A solid is characterized by structural rigidity and resistance to a force applied to the surface.
Both solids are supplied with an equal amount of energy. Out of both substances, substance 2 has a stronger molecular attraction due to which it can not easily change into a liquid while substance 1 has a lesser molecular attraction so supplying of few amounts of heat will change substance 1 into a liquid state.
Hence, Substance 2 has a stronger molecular attraction.

A. HF, because both fluorine and hydrogen are capable of forming only one ionic bond.
B. HF, because both fluorine and hydrogen are capable of forming only one covalent bond.
C. H2F, because fluorine is short of two electrons, and hydrogen is short of one electron.
D. H2F, because fluorine is capable of forming one, and hydrogen is capable of forming two covalent bonds.
Thank you
The answer is B
HF, because both fluorine and hydrogen are capable of forming only one covalent bond.
The formula for a compound made from fluorine and hydrogen is HF, because both fluorine and hydrogen are capable of forming only one covalent bond. The correct option is option B.
What is chemical Compound?Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion. Covalent bond is weaker than ionic bond.
There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron.
The formula for a compound made from fluorine and hydrogen is HF, because both fluorine and hydrogen are capable of forming only one covalent bond.

how does eating contribute to the flow of energy in a ecosystem
Answer:
Eating contributes to the flow of an ecosystem because in a food web/chain, there is always a consumer. Starting from the very bottom of the food web/chain, all organisms eat to pass on the energy to the next cosumer. For example, a grasshopper eats some grass. That grass is made into energy. Then, a possum eats that grasshopper, the energy from the grasshopper converting to the energy of the possum. Then a giant snake comes along and eats the possum. The energy keeps flowing up and up the food chain as animals consume(and be consumed).

An atom has an atomic number of 15 and a mass number of 31. How many protons are there in the atom?
Answer:
No of protons = 15
Explanation:
Given that,
Atomic number = 15
Mass number = 31
We need to find the no of protons in the atom.
We know that,
No of protons = Atomic no of the atom
No of protons = 15
Hence, there are 15 protons in the atoms.
CaO + H2O -> Ca(OH)2
3.50g of Ca(OH)2 was made from 4.20g of CaO? What is the % yield of Ca(OH)2?
The % yield of Ca(OH)₂ : 62.98%
Further eplanationPercent yield is the compare of the amount of product obtained from a reaction with the amount you calculated
General formula:
Percent yield = (Actual yield / theoretical yield )x 100%
An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients
Reaction
CaO + H₂O ⇒ Ca(OH)₂
mass CaO= 4.2 g
mol CaO(MW=56,0774 g/mol) :
[tex]\tt mol=\dfrac{mass}{MW}\\\\mol=\dfrac{4.2}{56,0774 g/mol}\\\\mol=0.075[/tex]
mol Ca(OH)₂ based on mol CaO
mol ratio CaO : Ca(OH)₂,= 1 : 1, so mol Ca(OH)₂ = 0.075
mass Ca(OH)₂(MW=74,093 g/mol) ⇒ theoretical
[tex]\tt mass=mol\times MW\\\\mass=0.075\times 74,093 g/mol\\\\mass=5.557~g[/tex]
% yield :
