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

The equation for the reaction;

  CuO(s) + H₂(g) → Cu(s) + H₂O(g)

We are given;

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

Thus, moles of CuO = 12 moles

Therefore; 12 moles of CuO will be required.

n+h→nh3

we must remember that nitrogen and hydrogen are both diatomic molecules in their standard gas form. this adjusts the equation to

n2+h2→nh3

now we need to adjust coefficients in order to balance the atoms on each side of the equation. currently we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.

we can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.

n2+3h2→2nh3

this gives us 6 hydrogen on each side and coincidentally the nitrogens now equal 2 on each side.

answer; ///i do believe that the correct answer is (b); ///particle composed of two or more atoms bonded together;
