Octane on combustion yields CO₂ and H₂O;

                         2C₈H₁₈<span>  +  2 5O</span>₂    →    16 CO₂<span>  +  18 H</span>₂<span>O
</span>
According to equation,

                      2 moles Octane produces  =  16 moles of CO₂ 
So,
              498 moles Octane will produce  =  X moles of CO₂

Solving for X,
                                     X  =  (498 mol × 16 mol) ÷ 2 mol

                                     X  =  3984 moles of CO₂

Now,
Calculating for Volume,
As,
                                    P V  =  n R T
Solving for V,
                                        V  =  n R T / P       ------- (1)

Pressure  =  P  =  0.995 atm 
<span>Volume  =  V  =  ? </span>
<span>Moles  =  n  =  3984 </span>
<span>Gas Constant  =  R  =  0.0821 L.atm.K</span>⁻¹.<span>mol</span>⁻¹<span> </span>
<span>Temperature  =  T  =  23 + 273 = 296 K
</span>
Putting values in eq. 1

                V  =  (3984 mol × 0.0821 L.atm.mol⁻¹.K⁻¹ × 296 K) ÷ 0.995 atm

                                      Volume  =  973040.95 L

Nesterboy [21]

Answer:

The isopropanol evaporated while the water did not because the molecules don't stick together as strongly as the molecules in the water do. The water would need more energy transferred in, in order to evaporate.

Which statement best describes the amount of catalyst that remains at the end of a reaction?
Ivenika [448]
I believe the correct answer is C. The amount of catalyst is the same at the end as at the beginning of the reaction. Catalysts can't be consumed by the reaction thus is not D.
