Chemistry

When aluminum is heated with molecular oxygen gas, aluminum oxide is formed Molar masses: Al - 279 0 - 160
a) Write the balanced chemical reaction for this process:
Al +__0,- _ALO,
b) If one started with 50 grams of the metal Al..
1. How much Al in moles does one have show by FIM
c) How many moles of O, does one need to react all the Al above? Show by
FLM
1. How many grams of O, does one need to react to all the AI? Show
by FLM
2. How many LIters of O, does one need to react all the Al? Show by
FLM
d) How many moles of Aluminum oxide can be made at most from the 50
grams of Al used and the oxygen supplied? Show by FLM
e) How many grams of Aluminum oxide can be made at most from the
50 grams of Al used and the sufficient amount of oxygen supplied? Show
by FLM
F) If only 25 grams of aluminum oxide were recovered from the reaction by
chemists in the lab, what would be the % yield of the reaction?
