Select from the dropdown lists to complete the text.

Iron can be extracted from iron oxide using a process called ( reduction, oxidation, electrolysis ). This involves heating the ore with ( carbon monoxide, carbon dioxide, sulfur dioxide, copper ) to remove the oxygen from the compound. This process is also called a ( displacement, combustion, hydrolysis ) reaction, and gives two products: iron and ( carbon dioxide, carbon monoxide, copper ).

Fill the blank spaces to complete the text.

A student wants to make a metal salt. He decides he is going to use copper oxide and sulfuric acid as his starting materials, and adds 20 ml of acid to 2 g of the metal oxide. He finds that the solution makes the reaction happen faster. Eventually the reaction stops and there is still some copper oxide left, and notes that this must mean the copper oxide was added in . He also notes that the solution has now turned blue, and starts to filter off the remaining solid. To get the salt out of solution he needs to the water off, and sets up his equipment. He decides to only remove a small amount of water, and leave it to crystallise out over night. When he comes back in the morning he finds lovely blue crystals of copper .

1

The ❌ series can be used to see the relative tendency for metal ❌ to form ❌ - the higher up the series, the more likely it will form a ❌ ion.

Something similar can be said for a metal's resistance to ❌ - the higher up the series, the more easier it is to ❌.
