Endothermic reaction is the reaction in which energy is obserbed for the change.

Chemical weathering is the process of altering rocks chemically when they are broken down. It includes hydrolysis, oxidation, acid rain, etc...

The Standard hydrogen electrode (abbreviated SHE), is a redox electrode which forms the basis of the thermodynamic scale of oxidation-reduction potentials. Its absolute electrode potential is estimated to be 4.44 ± 0.02 V at 25 °C, but to form a basis for comparison with all other electrode reactions, hydrogen's standard electrode potential (E0) is declared to be zero volts only at 298.

Ammonia can be dried by Calcium Chloride or calcium hydroxide.

Due to the molecules present in the 2,2-dimethylbutane are closely packed, it has the highest boiling point.
