Refer to the following microscale experiment: (b) Write the equation for the reaction involved in (a). (c) The gas is then allowed to flow through a delivery tube containing copper(II) oxide. The gas and copper(Ii) oxide react upon heating. (i) What observable change can be observed about the copper(II) oxide? (ii) Write the chemical equation for the reaction occurred and state the reaction type involved. (d) State one advantage of carrying out this experiment on a microscale
