Bell Work NH 3 + O 2  N 2 + H 2 O How many moles of oxygen react with 0.23 moles of NH 3 ?

Limiting Reagent

Game of Ratios Make a Table Write the ratios Write multiple ratios

O 2 + 2NO  2NO 2 Amt O2Amt NOAmt NO2 Limiting Reactant Excess 1 molecule 2 molecule 4 molecule 2 molecule 8 molecule

Complete Worksheet Numbers 1 to 18

Questions What would be different if you had mass instead of moles? What is the difference between a limiting reagent and excess reagent?

C 1 1 H 4 2 O 2 3

ID the limiting reagent. How do you know?
