the following equitations below is incorrect and why as well as

Hi i’m needing help with my discussion post Give three chemical equations for three reactions one of which is incorrect. Please let me know which one is incorrect in your response so I can note it. Also i need the source cited from where the info was found. Please let me know if you have questions.Also can you please tell me which of the following equitations below is incorrect and why as well as what they should be?first setN2 O2 ( energy) = 2NOH2 O=2HO2Mg O2=2MgOsecond setExample the combustion reaction of propane found in gas grills and some fireplaces is:C3H8 5O2 ? 4H2O 3CO2 energy2. The passage of an electric current through water forms hydrogen and oxygen gas at the electrodes. Is this a combination or decomposition reaction?Example: H2O?H2 O2 This is a decomposition reaction Solution: H2O?2H O23. Aluminum hydroxide is found in Di-Gel (antacid) and Mylanta.Example: HCI Al(OH)3?Solution: 3 HCI Al(OH)3? 3 H2O AlCl3
