Question

3Pb + 2H3PO4 →3H2 + 1Pb3(PO4)2

  1. Synthesis (or combination)
  2. Decomposition
  3. Single displacement
  4. Double displacement

hintHint:

Only one displacement takes place.

The correct answer is: Single displacement


    The word displace means to push out. A more reactive element can displace a less reactive element out of its compound during a chemical reaction, this reaction is termed as displacement reaction.
    Single displacement reaction can be termed as when only one displacement take place in a reaction.
    A single displacement reaction is a chemical reaction which occurs when one part of a compounds is exchanged with another element forming a new compound.
    3Pb + 2H3PO4 →3H2 + 1Pb3(PO4)2

    Here phosphate is exchanged to lead.
