The following reaction does not proceed to a product: H2O + Cu --> no reaction. Why is that?
a.Copper has a lower activity than hydrogen and cannot replace it.
b.The reaction cannot occur because water is a reactant.
c.Copper has a higher activity than hydrogen and cannot replace it.
d.The reaction proceeds too slowly to create products.

Respuesta :

I think the correct answer would be because copper has a lower activity than hydrogen and cannot replace the bonds in it. Substances that are not oxidizing do not react with copper since the redox potentials are very low. Hope this answers the question.

   The  reason why  H₂O +Cu  does   not  proceed to  a  product  is that  

copper  has  a   lower   activity  than  hydrogen  and  cannot  replace  it (answer  A)


Explanation

Replacement reaction is type  of  a reaction in which  element react with compound  and take place of  another element  in that compound.

That  is the   more  reactive  element replaces  the less  reactive  element from it's compound.

Since  H₂  is  more  reactive  than Cu  in  reactivity  series therefore   no reaction  occur  between  H₂O  +Cu  since   Cu cannot  replace H₂  from its  compound.
