power
Renewable Resources
Nonrenewable Resources
steel

hydroelectric powwer
coal and oil
gemstones
Wind power and hydroelectric power are renewable resources whereas, steel, gemstones, apple tress coal and oil etc. are non- renewable sources. Hence, they cannot be regenerated when exhausted.
What are renewable sources ?Renewable sources are resources that can used for longer period or eternal. They can be regenerated and reused even after consumption of the existing amount. Wind power, solar power, hydroelectric power etc. are renewable sources and they are nature genuine.
Non- renewable sources are those which cannot be regenerated once they are exhausted. For example, petroleum, coal, oil, diesel etc. are non-renewable because, once they completed from the earth, they cannot be regenerated or excavated.
Non-renewable sources are creating pollution by the production of toxic hydrocarbon gases as well. Gemstones are non renewable because, once they consumed, they cannot be generated.

Which of the following statements best describes how the speed and velocity of an object differ?
Answer:
Speed is the time rate at which an object is moving along the path, while velocity is the rate and direction of the object's movement. put another way, speed is a scalar value while velocity is a vector value.

What is an orbital? How does it differ from an orbit?
Answer:
An orbit is the simple planar representation of an electron. An orbital refers to the dimensional motion of an electron around the nucleus in a three-dimensional motion. An orbital can simply be defined as space or the region where the electron is likely to be found the most.
Explanation:
Answer:
An orbital on the other hand is simply the probable area where one can expect to find the maximum density of electron presence within an atom. An orbit on the other hand is simply present in a body with a certain mass, while an orbital exists for an electron as well as an atom.
Thus, these are the simple differences between Orbit and Orbitals. It is important to know the major differences, you can check out the differences between Orbit and Orbitals below:
Differences between Orbit and Orbitals
Orbit Orbitals
An orbit is the simple planar representation of an electron. An orbital refers to the dimensional motion of an electron around the nucleus in a three-dimensional motion.
It can be simply defined as the path that gets established in a circular motion by revolving the electron around the nucleus An orbital can simply be defined as the space or the region where the electron is likely to be found the most.
The shape of molecules cannot be explained by an orbit as they are non-directional by nature. The shapes of the molecules can be found out as they are directional by nature.
An orbit that is well-defined goes against the Heisenberg principle. An ideal orbital agrees with the theory of Heisenberg’s Principles.
Thus, these are the major differences between Orbit and Orbitals.

Why it is necessary for plants to have chloroplasts?
In your own words, please
Chloroplasts is an important part in the process of photosynthesis in some organisms. The chloroplast absorbs the energy in sunlight and uses it to produce sugars.
The main function of chloroplast in plants is to convert light energy into chemical energy via the photosynthesis process.
What is the role of chloroplasts in plants?Photosynthetic chlorophyll is found in chloroplasts, which catch sunlight and converts it into chemical energy, releasing oxygen from water. All green plants and algae have chloroplasts. Chloroplasts help plants in the formation of food.
Chloroplasts are found in the leaves of the plant's guard cells. Chloroplasts contain a lot of chlorophyll, which helps to trap sunlight. The chloroplast is capable of reproducing without any help from the rest of the cell.
The primary job of chloroplast is to produce food through the photosynthesis process. Chloroplast has a component called chlorophyll, which traps sunlight and is used for food synthesis or sugar and other organic molecules in all green plants. They also form lipid components and amino acids that are required for chloroplast membranes.

Aluminum metal reacts with hydrochloric acid to produce solid aluminum chloride and hydrogen gas. how many moles of aluminum are needed to produce 1.2 moles of hydrogen gas?
Moles of Aluminum needed : 0.8
Further explanationGiven
1.2 moles H₂
Required
moles of aluminum
Solution
The reaction coefficient in a chemical equation shows the mole ratio of the components of the compounds involved in the reaction (reactants and products)
Reaction(balanced equation)
2Al + 6 HCl = 2AlCl₃ + 3H₂
From the equation, mol ratio of Al : H₂ = 2 : 3, so mol Al :
= 2/3 x mol H₂
= 2/3 x 1.2
= 0.8 moles

PLEASE HELP!! Sulfur dioxide gas and oxygen gas react to produce gaseous sulfur trioxide. What mass of sulfur trioxide is produced when 125 g of sulfur dioxide reacts with 50.00 g of
oxygen to produce sulfur trioxide as the only product.
2SO2(g) + O2(g) —> 2SO3(g)
Answer:
Mass = 156.195 g
Explanation:
Given data:
Mass of SO₂ = 125 g
Mass of O₂ = 50.00 g
Mass of SO₃ produced = ?
Solution:
2SO₂ + O₂ → 2SO₃
Number of moles of SO₂:
Number of moles = mass/molar mass
Number of moles = 125 g/ 64.1 g/mol
Number of moles = 1.95 mol
Number of moles of oxygen:
Number of moles = mass/molar mass
Number of moles = 50.00 g/ 32 g/mol
Number of moles = 1.56 mol
Now we will compare the moles of SO₃ with SO₂ and O₂
O₂ ; SO₃
1 ; 2
1.56 : 2/1×1.56 = 3.12 mol
SO₂ ; SO₃
2 ; 2
1.95 : 1.95
Less number of moles of SO₃ are produced by SO₂ it will act as limiting reactant:
Mass of SO₃ :
Mass = number of moles × molar mass
Mass = 1.95 mol × 80.1 g/mol
Mass = 156.195 g

Two atoms of the same element cannot have different numbers of _____.
a. particles c. protons
b. neutrons d. electrons.
Answer:
c. protons
Explanation:
A "proton" is a subatomic particle that is stable and is positively-charged. You will identify the number of protons that is present in the nucleus of a chemical element by its "atomic number." It gives us an identity of the element, therefore, every atom of the same element have the "same" number of protons. For example, the number of protons for "Hydrogen" is 1. This means that even if you have two atoms of Hydrogen, each of them has "1" as the number of proton.

What is “the process in which electrons are rearranged without direct contact”???
Answer:
Induction
Explanation:
The process whereby electrons are rearranged without direct contact with one another is called induction.
By induction electrons can get charged without them having to be in contact with one another.
When a charged body is brought to the vicinity of the electrons, either an attraction or repulsion force is set up. Similar charges causes repulsion If a negatively charged body is brought near the electrons, there would be heavy repulsion and the electrons would be forced to rearranged. This effect is product as a result of a force field.Consider the decomposition of hydrogen peroxide reaction. If the rate of decomposition of hydrogen peroxide at a particular temperature is determined to be 0.098 mol/(L·s), what are the rates of reaction with respect to the products of the decomposition reaction?
Answer:
0.049 mol/L.s
Explanation:
The decomposition of hydrogen peroxide is:
[tex]H_2O_2 \to H_2O + \dfrac{1}{2}O_2[/tex]
[tex]Rate = -\dfrac{\Delta [H_2O_2]}{\Delta t}= \dfrac{\Delta [H_2O_2]}{\Delta t}= \dfrac{ 2 \Delta [H_2O_2]}{\Delta t}[/tex]
The rate of decomposition reaction = the rate of formation of [tex]H_2O[/tex] = 0.098 mol/L.s
∴
Rate of formation of [tex]O_2[/tex] [tex]= \dfrac{ rate \ of \ reaction }{2}[/tex]
[tex]= \dfrac{ 0.098 }{2}[/tex]
= 0.049 mol/L.s
