The reaction CO₂(g) → C(s) +O₂(g) is a decomposition reaction is true

The reaction above is a decomposition reaction since CO₂ molecule is broken down into C (an element) and O₂ (a molecule).
mass spectrum of tertiary butyl chloride having overall mass as 92 m /Z for Cl35 and 94 m /Z for Cl37. The major peak at 57 m /Z for the removal of chlorine - 37 radical whereas other peak appear at 77 m /Z after removal of a methyl radical.
Ir of tertiary butyl chloride appear majorly at 3000 Cm^-1 whereas other small peaks appear between 1400- 1550 Cm-1
