It has 4 atoms in one cell, and the atomic volume is about half that of GaAs. Because of its high hardness, it is also a good coating protection material. At room temperature, GaN is insoluble in water, acids and bases, but dissolves very slowly in hot alkaline solutions. NaOH, H2SO...
Unlike the halides of the other elements in the group they are monomeric in the gas, liquid and solid states, BF3 and BCl3 are gases, BBr3 is a volatile liquid and BI3 is a solid. Boron trihalides are Lewis acids because they form simple Lewis complexes with suitable bases, as in the...
The value of pH for acids varies from 0 to 7. The value of pH for bases varies from 7 to 14. The pH value of a neutral substance is 7. The pH scale can be represented as: 624c07f19e56cd80e61a8fbb Similar questions Q.(a) Define pH. ...
Explain the purpose of using a washing buffer in RNA extraction, and explain how an elution buffer differs from a washing buffer. RNA: RNA stands for ribonucleic acid, and one type is formed from DNA by a process of transcription. It consists of ...
