The balanced equation for the reaction of calcium and oxygen to form calcium oxide is:
2Ca + O2 -> 2CaO
From the equation, we can see that 2 moles of calcium react with 1 mole of oxygen to form 2 moles of calcium oxide.
Given that there are 3 moles of calcium and 3 moles of oxygen, we can determine that the limiting reactant is oxygen since there is an excess of calcium.
Since 1 mole of oxygen reacts to form 2 moles of calcium oxide, 3 moles of oxygen would theoretically produce 6 moles of calcium oxide.
Therefore, 6 moles of calcium oxide would be produced.
The remaining calcium, which is in excess, would be unreacted.
3mole of calcium and 3mole of oxygen react then .
How many moles of calcium oxide produce?
What mole reactant remains unreacted ?
