Dear student, A Chemical combination is a chemical reaction in which two or more substances combine to form a new substance If P and Q are two reactants that combine to give R as the product, then the chemical change is a chemical combination reaction P + Q → RExample: (i) Reaction of carbon with oxygen to given carbon dioxideC + O2 → CO2(ii) Reaction of calcium with oxygen to give calcium oxide2Ca + O2 → 2CaO For remaining queries we request you to post them in separate threads to have rapid assistance from our experts Regards
