<span>Fluorine is the most chemically reactive element on the periodic table, and there are no chemical substances that are capable of freeing it from its bonds.

I’m going to go with The pH 1 solution is two times more acidic than that with a pH of 1. If that’s not the answer, then my second best guess would be The pH solution is ten times more acidic than that with a pH of 2.
The first and third answer choice wouldn’t even be an answer so you can just cancel those two out and pick between answer choice 2 or 4.
Hope this helps, and have an amazing day!! :))
2C₃H₇OH + 9O₂ = 6CO₂ + 8H₂O
V(O₂)=12.0 dm³
n(C₃H₇OH)=0.1 mol
n(O₂)=12.0 dm³/22.4 dm³/mol=0.5357 mol
C₃H₇OH : O₂ 2:9 1:4.5
0.1:0.5357
oxygen in excess
V(CO₂)=3Vm*n(C₃H₇OH)
V(CO₂)=3*22.4*0.1=6.72 dm³
