Eg:- fossil fuels, crude oil/petroleum, natural gas, and nuclear fuels.
Explanation:
Renewable resources are those resources that can be repeatedly used and cannot run out of stock as they are naturally replaceable.
Eg:-Wood,Paper,Cotton
Among the options mentioned in the above question steel is not a renewable resource. Steel is made up of iron ,which is mined from the ground.
Brainliest?
The statement is "the steel frame used to make the bike."
What is non-renewable resourceA non-renewable resource is one that cannot be replenished by natural processes at a rate fast enough to keep up with use. Carbon-based fossil fuels are an example.
Metals are essential and valuable resources in general. Metals are extremely recyclable and reusable, despite the fact that their natural supply or the supply of components used to make diverse alloys are set.
Steel is created from iron, a nonrenewable resource.
Hence the correct option is A.

Each B atom is adjacent to 2 A atoms and 2 B atoms. What is the B-C-B angle ?
Answer:
120 degrees
Explanation:
The molecule has trigonal bipyramidal geometry. The angle between B molecules is 120 degrees. The angle between A and B molecules is 90 degrees.
The bond angle of B-C-B is equal to 120° as the given geometry of the molecule is trigonal bipyramidal.
What is the trigonal bipyramidal geometry?The trigonal bipyramid formation in chemistry is a molecular geometry in which one atom is at the center and 5 more atoms are at the corners molecular structure.
The bond angles of this geometry surrounding the central atom are not identical because there is no geometrical arrangement with five terminal atoms in equivalent positions. For example, this molecular geometry is PF₅, PCl₅ in the gas phase.
In PCl₅, the P atom shares a plane with three Cl atoms at 120° angles to each other in equatorial positions, and two more Cl atoms above and below the plane or at axial positions. An axial atom has three neighboring equatorial atoms at a 90° bond angle.
In the given figure, the B-C-B is present at the equatorial plane of the molecule. The angle between the bonds at the equatorial plane is 120°. Therefore, the angle of B-C-B is equal to 120°.

How many electrons does the Mg+2 ion have?
Answer:
10 electrons
Explanation:
The easiest way to do this is to simply look at the periodic table, find the atomic number of magnesium, and subtract 2 from it. The reason this works is that the atomic number tells you how many protons an element has. If we want the element to be neutral, then by definition it will have the same number of electrons.
Answer:
10 Valence Electrons
Explanation:
Easiest thing to do is to look at your periodic table :)

Lewis Dot structure for N2?
PHOTO ABOVE
Is not D I got it wrong
Answer: C
Explanation:
The N2 should have a triple bond because it needs three covalent bonds to fill its outer shell. This means the two atoms need to share three electrons each.
It also serves as a nice illustration of a triple-bonded molecule. For the Lewis structure of N2, there are ten accessible valence electrons. Therefore, option C is correct.
What is lewis structure ?The diagrams known as Lewis structures, often referred to as Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures, depict the interactions between the atoms in a molecule as well as any lone pairs of electrons that may be present.
It contradicts the octet rule, as shown by the production of molecules, and could not account for the release of energy during the formation of covalent bonds.
The three parallel lines between the N atoms represent three bonds. This is a triple bond, with one electron from each N atom contributing to each bond. A total of 6 electrons are thus represented by this triple bond.
Thus, option C is correct.

The correct Lewis Dot Structure for Nitrogen is structure C. Therefore, option C is correct.
What is lewis dot structure ?The valence shell electrons in a molecule are depicted in an extremely simplified manner by a Lewis Structure. It is used to demonstrate how the electrons in a molecule are positioned around particular atoms.
Gilbert N. Lewis, who first described it in his 1916 article The Atom and the Molecule, gave the Lewis structure its name. Lewis structures add lines between atoms to represent shared pairs in a chemical bond, extending the idea of the electron dot diagram.
In Nitrogen molecule, every nitrogen atom has five valence electrons and there is a triple bond between the two nitrogen atoms. Thus, the correct lewis dot structure is; :N⋮⋮N: .

A.
gases only
ОВ.
solids, liquids, and gases
solids and liquids only
C.
D.
solids only
Reset
Submit
Answer:
A. gases only
Explanation:
It is only in gases that the particles are very far apart so they can fill their contains.
There are four major states of matter which solid, liquid, gases and plasma.
Particles of a gas have very weak attractive forces between them. They do not have fixed volume nor shapeThey easily fill up any containers they are put into. Gases are compressible and moves randomly in a straight line. Liquids and solids do not fill up containers. Liquids although have weak forces but they are better attracted than gases. Solids have fixed and definite volume.So, option A is the perfect answer.

hope this helps you out bro
Answer:
The order is B, C, A.
Explanation:
When the liquid is first poured into the container, the entropy is still very high because there is a very large difference in color of the liquid. The more time passes, entropy becomes lower because the blue color liquid disperses through the rest of the container. So the entropy is the highest in B and lowest in A. At A the entropy is as close to 0 as it can be in this situation out of the three parts.
