Answer: 10.3 grams of Copper oxide is left unreacted.
Explanation:
To calculate the moles :
The balanced chemical reaction is:
According to stoichiometry :
1 moles of require = 1 mole of
Thus 0.5 moles of will require= of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
moles of CuO left = (0.63-0.5) mol= 0.13 mol
Mass of left =
10.3 grams of Copper oxide is left unreacted.
hope this helps
Keep studying and good luck in your stoichiometry test
