single displacement

is a reaction in which a free atom becomes an ion and an oion becomes a free element

equation- A+B=AC+B ex: CuSO4+Fe=FeSO4+Cu(+1)

what you would do because it is not balanced is that you would put a 1 in front of the Cu on the right and then put a 1 in front of all the other elements in the equation
