Question

when hydrogen gas is passed over heated copper oxide Copper and steam are formed write the balanced chemical equation with the physical States for this reaction state what kind of chemical reaction in this

Answer 1

H2(g)+CuO(s)---> Cu(s)+H2O(g)
This is a redox reaction. Here Copper oxide is being reduced to form Copper while hydrogen is being oxidised to form water...

Answer 2

Answer:

CuO(s)+H2(g) --> Cu(s)+H2O(g)

Explanation:

it is a kind of redox /displacement reaction as H2 displaces CuO to form Cu and H2O. also hydrogen gas reduces the compound. here H2 is reducing agent and substance reduced is CuO.
