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
Petroleum Refining is defined as the industrial process of production of useful petroleum products from crude oil. The crude oil in its raw form is a dark and sticky liquid which is not useful. To get the usable products from the crude oil, it needs to be refined.
The sample path length and concentration of the sample are directly proportional to the absorbance of the light.
Amines are functional groups and compounds having a basic nitrogen atom with a lone pair. In other terms amines are the derivatives of ammonia(NH3)
The algebraic sum of ALL the currents entering and leaving a node must be equal to zero, the algebraic sum of all voltages within the loop must be equal to zero
The Molecular orbital theory was utilised initially to emphasize the bonding in molecules as the valence band theory could not explain the bonding in molecules.
Polyvinyl chloride is produced from the main component. It is white, brittle solid material available in powder form or granules.
Li-ion batteries are able to be recharged hundreds of times and are more stable
Smelting, is a process in metallurgy, where the metal obtained from its ore by heating beyond its melting point, in the presence of oxidizing agents,
Buffers are generally characterised by pH range by which they maintain a more or less constant pH by their buffer capacity.
