Question

Consider the following reaction:2CuS(s) + 3O_{2}(g) → 2CuO(s) + 2SO_{2}(g)Initially, the reaction mixture contains 3.0 mol CuS and 4.0 mol O_{2}. How many moles of the excess reactant remains after the reaction has occurred completely?

Accepted Answer

0.33 mol CuS

Answer

0.67 mol O_{2}

Answer

0.67 mol CuS

Answer

0.33 mol O_{2}

Consider the following reaction:2CuS(s) + 3O2(g) → 2CuO(s) + 2SO2(g)Initially, the reaction mixture contains 3.0 mol CuS and 4.0 mol O2. How many moles of the excess reactant remains after the reaction has occurred completely?

Consider the following reaction:
2CuS(s) + 3O₂(g) → 2CuO(s) + 2SO₂(g)
Initially, the reaction mixture contains 3.0 mol CuS and 4.0 mol O₂. How many moles of the excess reactant remains after the reaction has occurred completely?
