chemistry P6 and P7 0.0 / 5 ? ChemistryElectrolysisGCSEAQA Created by: Joel ChadwickCreated on: 31-10-17 18:29 What goes to the anode in electrolysis? positive ions 1 of 16 what goes to the cathode in electrolysis? negative ions 2 of 16 give the definition of electrolysis? splitting ions using electricity 3 of 16 what is produced if the metal is more reactive than hydrogen? hydrogen 4 of 16 what is produced unless the solution contains a haylide? oxygen 5 of 16 is a gas produced at the anode? it is produced at the cathode. 6 of 16 would carbon displace aluminium~? carbon would not displace aluminium because aluminium is higher on the reactivity series. 7 of 16 define endothermic reaction endothermic reactions transfer energy from their surroundings to the reaction 8 of 16 define exothermic reactions exothermic reactions transfer energy from the reaction to their surroundings 9 of 16 metal + acid = metal salt +hydrogen 10 of 16 metal carbonate +acid = metal salt + water+ carbon dioxide 11 of 16 base + acid salt+ water 12 of 16 metal + oxygen metal oxide 13 of 16 alcohol +oxygen carbon dioxide + water 14 of 16 metal carbonate + acid salt + carbon dioxide + water 15 of 16 breaking bonds take in energy from the surroundings. What reaction is this? Exothermic reaction 16 of 16
