Limiting reagents are the substances that are completely consumed in the completion of a chemical reaction. They are also referred to as limiting agents or limiting reactants. According to the stoichiometry of chemical reactions, a fixed amount of reactants is required for the completion of the reaction. Let us consider the following reaction of formation of ammonia:
3H2 + N2 → 2NH3

Mass percent of solute = mass of solute/ mass of solution×100
Mass of solute = 20 g
Mass of solvent = 80 g
Mass of solution = 20 g
∴ Mass percent of solute =20/20 × 100
=100%

An atom consists of a large number of orbitals which are distinguished from each other on the basis of their shape, size and orientation in space. The orbital characteristics are used to define the state of an electron completely and are expressed in terms of three numbers as stated, Principal quantum number, Azimuthal quantum number and Magnetic quantum number and Spin Quantum number.

Volume of the Solution = 250 cm³.
= 250 mL.
= 250 × 10⁻³ L.
Mass of the Oxalic Acids = 0.63 grams.
Molar Mass of the Oxalic Acid = 1236 g/mole.
For molarity,
∵ No. of moles = Mass/Molar Mass
∴ No. of moles = 0.63/126
= 5 × 10⁻³ moles.
Using the Formula,
Molarity (M) = No. of moles of the Solute/Volume of the Solution in liter
∴ M = (5 × 10⁻³)/(250 × 10⁻³)
M = 0.02 M
Hence, the molarity of the solution is 0.02 M.

The electron density is concentrated behind the nuclei of the two bonding atoms in anti-bonding molecular orbitals. This results in the nuclei of the two atoms being pulled away from each other. These kinds of orbitals weaken the bond between two atoms.

The set of numbers used to describe the position and energy of the electron in an atom are called quantum numbers. There are four quantum numbers, namely, principal, azimuthal, magnetic and spin quantum numbers.
The notion of energy levels and notation has been taken from the atom ‘s earlier Bohr model. Schrodinger ‘s equation evolved the concept from a two-dimensional flat Bohr atom to a three-dimensional model for wave motion. Where n = 1 , 2 , 3 is called the main quantity, and h is the constant of Planck.

The bond order shows the number of chemical bonds present between a pair of atoms. For instance, the bond order of diatomic nitrogen N≡N is 3 and bond order between the carbon atoms in H-H≡C-H is also three. The bond order describes the stability of the bond. The molecular orbital provides an easy understanding of the concept of the bond order of a chemical bond. It quantifies the degree of covalent bonds between the atoms.
How to calculate Bond order?
The Bond Order Formula can be defined as half of the difference between the number of electrons in bonding orbitals and antibonding orbitals.
Bond order = 1/2 = Nb - Na
Where,
Nb is the number of bonding electrons
Na is the number of antibonding electrons

Dipole Moment Formula
A dipole moment is the product of the magnitude of the charge and the distance between the centers of the positive and negative charges. It is denoted by the Greek letter ‘µ’.
Mathematically,
Dipole Moment (µ) = Charge (Q) * distance of separation (r)
It is measured in Debye units denoted by ‘D’. 1 D = 3.33564 × 10-30 C.m, where C is Coulomb and m denotes a meter.
The bond dipole moment that arises in a chemical bond between two atoms of different electronegativities can be expressed as follows:
μ = ?.d
Where: μ is the bond dipole moment,
? is the magnitude of the partial charges ?+ and ?–,
And d is the distance between ?+ and ?–.

Stoichiometry as the calculation of products and reactants in a chemical reaction. It is basically concerned with numbers.
Stoichiometry helps us determine how much substance is needed or is present. Things that can be measured are;
- Reactants’ and Products mass
- Molecular weight
- Chemical equations
- Formulas
