Answer: The relation between the forward and reverse reaction is
Explanation:
For the given chemical equation:
The expression of equilibrium constant for above equation follows:
.......(1)
The reverse equation follows:
The expression of equilibrium constant for above equation follows:
.......(2)
Relation expression 1 and expression 2, we get:
Hence, the relation between the forward and reverse reaction is
b. density.
c. energy level.
d. specific heat.
The correct answer is (C) energy level.
The explanation:
When the electrons release photons , and those photons are at different levels
of energy . So we can define the electron's energy level from this photons which
tell us the energy level they are on.
Determining the number of atoms in a jar of liquid task most likely involves a calculation that uses moles.
The term mole is defined as a standard scientific unit for measuring large quantities of very small entities such as atoms, molecules, or other specified particles.
A mole is the amount of material including 6.023 × 10²³ particles. 1 mol = 6.023 × 10²³particles. This number is also called Avogadro's number.
In determining the number of atoms that makes up a substance, the number of moles is very necessary.
The mole is the favorable unit of quantity of particles. It can be likened to a quantity of things in everyday life like a dozen, a score and a gross.
A mole of any substance contains 6.023 x 10²³ particles
These particles can be atoms, protons, neutrons, electrons etc.
Thus, to find the number of atoms, we must know the number of moles.

Your answer is: determining the number of atoms in a jar of liquid.
(1) N2 (3) Na
(2) NH4+ (4) NaHCO3
The species that significantly represents a chemical compound is known as NaHCO3. This is also known as Sodium bicarbonate or sodium hydrogen carbonate. Thus, the correct option for this question is D.
A chemical compound may be defined as a type of chemical substance that is mainly composed of many similar molecules that contain atoms of more than one chemical element. These atoms are typically held together by chemical bonds.
According to the context of this question, Na is sodium and N2 is dinitrogen or simply nitrogen gas. Both these chemical constituents are classified as the type of chemical element. While NH4+ is a polyatomic ion which is known as an ammonium ion.
So, NaHCO3 is classified into the category of a chemical compound. This is because it mainly consists of sodium, hydrogen, carbon, and oxygen.
Therefore, the species that significantly represents a chemical compound is known as NaHCO3. This is also known as Sodium bicarbonate or sodium hydrogen carbonate. Thus, the correct option for this question is D.

Answer:
4.) NaHCO3
Explanation:
In a compound, two or more elements are chemically combined. NaHCO3 is a compound containing the elements sodium (Na), hydrogen (H), carbon (C), and oxygen (O). N2 and Na are elements. NH4+ is the polyatomic ion ammonium.Zoom
