Expert Answer:

Chemical reaction means formation of new compound not element – False

A chemical reaction is the change of a substance into a new one that has a different chemical identity.

There are chemical reactions in which elements get formed.

For example:

  1. HgO(s) → 2Hg(l) + O 2 (g)
  2. 2Al(s) + Fe 2 O3(s) → Al 2 O 3 (s) + 2Fe(l)
