Predict the products and balance the following equation: Li + O2
Predict the products and balance the following equation: 4 Li + O2 2 Li2O 4 moles of Li react with 1 mol of O2 to produce 2 moles of Li2O
4 Li + O2 2 Li2O If 1.83 mol of Li reacted, how many moles of O2 reacted? • What is the mole ratio of Li to O2? From the balanced reaction:
4 Li + 1 O2 2 Li2O If 1.83 mol of Li react, how many moles of O2 react? This is called the “Mole Ratio”
4 Li + O2 2 Li2O If 1.83 mol of Li reacted, how many moles of Li2O will be produced? “Mole Ratio” between Li2O and Li
