WebIron can react with oxygen to form iron (II) oxide. 2Fe + O 2 → 2FeO Iron can also react with oxygen to form iron (III) oxide 4Fe + 3O 2 → 2Fe 2 O 3 Nickel can react with oxygen to form nickel (II) oxide or nickel (III) oxide. c) Write two balanced symbol equations to show both reactions of nickel with oxygen. [2 marks] Assess your score Web11.Using the reaction from Q10. Choose 1 reaction you’ve ticked and explain why it happens. Choose 1 reaction you haven’t ticked and explain why it doesn’t happen. The ticked reaction happen, as the metal is more reactive than the metal in the compound so a displacement reaction takes place.
WebA salt and hydrogen are produced when acids react with metals. acid + metal → salt + hydrogen hydrochloric acid + magnesium → magnesium chloride + hydrogen 2HCl (aq) + Mg (s) → MgCl 2 (aq) + H 2 (g) Acids + Metal Oxides A salt and water are produced when acids react with metal oxides. acid + metal oxide → salt + water

Halogens react to gain an electron so they become more stable. The negatively charged electron is attracted to the halogen atom due to the positive charge of the atom’s nucleus. small mother of pearl necklace flower
