1) Calculate the energy released in the reaction between hydrogen and oxygen forming water as shown. H_(2(g))+O_(2(g))arrow H_(2)O_((g)

## Step1: Determine the balanced chemical equation### Ensure the chemical equation is balanced. For the given reaction, it is: ## Step2: Calculate the energy released by breaking bonds### Identify the bond energies involved. The bond energies can approximate the energy changes:- bond energy: 436 kJ/mol- bond energy: 498 kJ/mol- bond energy: 463 kJ/mol## Step3: Calculate the total energy required to break the bonds in the reactants### For the reactants, we have: ## Step4: Calculate the total energy released when forming the product bonds### For the products, we have: ## Step5: Calculate the net energy change### The net energy change can be found by subtracting the energy required to break bonds from the energy released in forming bonds:
