Me ! 14 points and brainliest to whoever answers it correctly ! 3. study the following reaction carefully. what classification should this reaction have? 2al + > 2albr3 + 3ni synthesis decomposition single replacement double displacement neutralization

It is a single replacement

because your doing a single replacement between 2AL and 3Ni 
2Al + 3NiBr2> 2AlBr3 + 3Ni

Yes it would be a physical change.

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.
