photosensitive substance forms silver and hydrogen gas in the presence of light
photosensitive substance combines with oxygen to produce silver oxide and chlorine gas
is known as synthesis reaction.

\(2AgCl → 2Ag + Cl_2\)
\(HCl + NaOH → NaCl + H_2O\)
\(CaCO_3 → CaO + CO_2\)
and
\(2AgBr → 2Ag + Br_2\)
\(Zn + CuSO_4 → ZnSO_4 + Cu\)
\(N_2 + 3H_2 → 2NH_3\)
\(KBr → 2K + Br_2\)
