Enthalpy is the measurement of energy in a thermodynamic system. The quantity of enthalpy equals the total content of heat of a system
Buffers are generally characterised by pH range by which they maintain a more or less constant pH by their buffer capacity.
According to Hund’s rule: Before the double occupation of any orbital, every orbital in the sub level is singly occupied.
Pauli exclusion principle states that no two electrons present in a single atom will have an identical set or will have the same quantum numbers
Enantiomers are a pair of molecules that exist in two forms that are mirror images of one another but cannot be superimposed one upon the other
water that contains a required quantity of dissolved minerals (like calcium and magnesium) ,Water hardness is usually measured as calcium hardness in milligrams per litre (mg/l)
The Aufbau principle highlights the way in which the electrons are filled in the atomic orbitals of an atom in its ground state
Hybridization is process, where the atomic orbitals having different shape and energy inter mingle together to form a set of similar orbitals
Quantum number is a value that is used to indicate the energy that is present in atoms and molecules, in addition an electron that exists within an ion or atom has four such numbers to exhibit the energy state
Chirality is an important property of asymmetry in many branches of science. A chiral molecule or ion exists in two stereoisomers that are mirror images of each other, called enantiomers
Enthalpy is the measurement of energy in a thermodynamic system. The quantity of enthalpy equals the total content of heat of a system
Enantiomers are a pair of molecules that exist in two forms that are mirror images of one another but cannot be superimposed one upon the other
It is a process that involves the protection of steel and iron from exposure to the atmosphere leading to rusting
Elastomers are polymers showing properties of both viscosity and elasticity and are also called viscoelasticity. The molecules of elastomers held together by weak intermolecular forces
Coagulation is a chemical process that is used in water treatment,a coagulant is added to remove the dispersed oils.
The sample path length and concentration of the sample are directly proportional to the absorbance of the light.
Li-ion batteries are able to be recharged hundreds of times and are more stable
