Answer:
Answer:1 When non-metals react with oxygen, they form acidic oxides or neutral oxides. Example: Carbon reacts with oxygen to form an acidic oxide called carbon dioxide. Hydrogen reacts with oxygen to form neutral oxide called water.
Answer:2
Iron and aluminium will displace hydrogen from dilute acids as they more reactive then hydrogen. Mercury and copper cannot displace hydrogen from dilute acids as they are less reactive than hydrogen.
