WebExample of chemical equation of respiration is given below: C6H12O6 (Glucose) +6O2 (Oxygen) = 6CO2 (Carbon Dioxide) + 6H2O (Water) In the above equation it is clear that Glucose is losing electron and producing carbon Dioxide. This is considered as a specific proof of oxidation reaction. Electrochemical reactions WebAnswer: (a) Two compounds unite to form a single substance in this equation. This is an example of a composition reaction. (b)Two separate substances combine to form two new ones. This is neither composition nor a decomposition reaction because it does not fit the definitions. This reaction is known as a double-replacement reaction. how to serve chow chow
