The number of moles of O2 that are needed to react completely with 35.0 mol C2H2 is; 87.5 mol of O2
<h3>Combustion Reaction</h3>
We are given The equation for combustion in an acetylene torch as;
2C2H2 + 5O2 --> 4CO2 + 2H2O
We are given;
- Acetylene tank contains 35.0 mol C2H2
- Oxygen tank contains 84.0 mol O2.
From the balanced equation above, we can see that;
2 mol of C2H2 reacts with 5 mol of O2
Thus, by proportion;
If 2 mol C2H2 = 5 mol O2
Then;
35 mol C2H2 = 35 mol C2H2 × 5 mol O2/2 mol C2H2
>> 87.5 mol of O2
