Study the following reaction carefully. what classification should this...
Single replacement reaction
-There are five general types of reactions . These includes; combination, decomposition, single replacement, double replacement, combustion.
-Single replacement reactions are reactions in which both reactants and products consist of an element and a compound . For example in our case, for reactants, the element is Aluminium (Al) and the compound is NiBr2, and for products the element is Ni and the compound is AlBr3.
-Single replacement reactions involves a chemical change in which one element replaces a second element in a compound . In this case Aluminium (Al) replaces nickel (Ni) in the compound NiBr2.
2 Al + 3 NiBr₂ = 2 AlBr₃ + 3 Ni
Classification : single replacement
hope this helps!
