Acetylene torches are used for welding, but the thermite reaction can be useful in situations in which acetylene torches are inappropriate, such as welding underwater. The thermite reaction is described by the equation below:
Upper F e subscript 2 upper O subscript 3 plus 2 upper A l right arrow upper A L subscript 2 upper O subscript 3 plus 2 upper F e. (see image)
