Balanced chemical reaction: CH₃CH₂OH + 3O₂ → 2CO₂ + 3H₂O.
CH₃CH₂OH is ethanol.
O₂ is molecule of oxygen.
CO₂ is carbon(IV) oxide.
H₂O is water.
There are same number of atoms (oxygen, carbon and hydrogen) on both side of balanced chemical reaction:
2 atoms of carbon.
6 atoms of hydrogen.
7 atoms of oxygen.
Answer:
26.2 atm
Explanation:
P1=P2V2/V1
P1=(1.05 x .980)/.0393
Answer: 26.2 atm
You can check this by knowing that P and V at constant T have an inverse relationship. Hence, this is correct.
