How many moles of cuo would be required to produce 12 mol of copper metal in this reaction? cuo(s) + h2(g) —— cu(s) + h2o(g)

12 moles

Explanation:

The equation for the reaction;

  CuO(s) + H₂(g) → Cu(s) + H₂O(g)

We are given;

Moles of copper, Cu is 12 moles

We are required to calculate the number of moles of CuO required;

From the reaction 1 mole of CuO reacts to produce 1 mole of copper Thus, the mole ratio of CuO to Cu is 1 : 1Moles of CuO = Moles of Cu

Thus, moles of CuO = 12 moles

Therefore; 12 moles of CuO will be required.

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.

The answer is c.  h+  and oh−  react to form water (h2o). i just took the test and i got it right. hope this !
