Chemistry Questions

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.

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

A nitrogenous base is an element that contains nitrogen that have same chemical properties of the base.

Covalent bonds are bonds formed between two non metals by sharing of electrons in their outer most orbits for stable.
