C=O bond vibrates more 7 of 9 Give two examples of Carbon capture and Storage. 1) Its injected deep into the ocean/sea. 2)Stored in old gas fields. 8 of 9 State two benefits (other than cost) of using enzymes to catalyse reactions 1)Reduces CO2 emission by burning less FF for energy. 2)Greater Etom Economy 9 of 9
