Question

Recognize and record individual elements , number of atoms of an element and identify its type of H2SO4 and NaHCO3.

Answer 1

Answer:

hydroclohric acid and iodine

Answer 2

no of elements =3<H2SO4>(H,S,O)

                          =4<NaHCO3>(Na,H,C,O)

number of atoms = 2(H)+1(S)+4(O)=7<H2SO4>

                              = 1Na+1H+1C+3O<NaHCO3>
