Which is an acid-conjugate base pair?
O NHA and NH3
O NH4" and H30*
O H20 and NH3
O H20 and H20"

Answer) by studying proton collisions hope this : )

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.
