There is more than one kind of balance used in the laboratory.

I don't know what your answer is looking for but the most common type of valence that I have come across in lab is an analytical balance. They are very accurate as well as precise. There are also top loading balances, spring balences, platform balanced, trip balances, and torsion balances. I don't know what the applications are for these balences. As I said before, I have only used analytical balenced in lab.

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.

Its trait is different and it the organism survive
