In thermodynamics the symbols like `DeltaH`, `DeltaS` and `DeltaG` are commonly used.
how are they related?

In thermodynamics the symbols like DeltaH , DeltaS and DeltaG are commonly used. What do the symbols DeltaH , DeltaS and DeltaG denote?

Bond order is a term commonly used in MO theory. How is it calculated ?

Second law of thermodynamics deals with the spontanelty of a process. Iron is extracted from the ore Fe_2O_3 . Using the date given above suggest whether the decomposition of Fe_2O_3 is feasible or not. Substantiate. (DeltaH^@= 824 kJ//mol, DeltaS^@ + 0.276 kJ//mol K, T = 298 K).

Write the condition of temperature for a process to be spontaneous whose DeltaH and DeltaS values are positive. [Hint: DeltaG = DeltaH - TDeltaS]

How much money does 4 ten- rupee notes and 3 five - rupee notes make?Using t for the number of ten rupee notes, f for the number of five rupee notes, and m for the amount of money they together make, write the relation connecting t, f and m :

In addition to the standard ring systems (such as cyclohexane ), cyclic compounds can also be bicyclic, tricyclic, etc., or they can be spirocyclic, bicyclic or bridge head carbons. The point of attachment of two rings are called bridge head atoms. Some bicyclic compounds like camphor are commonly found in plants. Others like norbomane can be synthesized in the laboratory. The formal names of bicyclic and related ring systems are based on: 1) Total number of atoms in the molecule. 2) The number of atoms in each bridge connecting the bridge head atoms. These numbers are written in square bracket in decreasing order. Spirocyclic compounds have two fused rings, but only one bridge head atom. Spirocyclic compounds are named like bicyclic compounds, but have the prefix spirocyclo. Select the correct statement about the following compounds:
