Benzene, c6h6, reacts with oxygen, o2, to form co2 and h2o. how much o2 is required for the complete combustion of 1.0 mol c6h6?

7.5 mol of oxygen are required

Explanation:

Hi, as it says, this is a combustion reaction of benzene:

The first step is to balance the equation:

1 mol of for each C in the benzene

1 mol of for each two H in the benzene

1 mol of for each and 0.5 mol for each

Balanced:

Now, following the reaction:

For 1 mol of benzene, 15/2 (7.5) mol of oxygen are required.  

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
