I believe the the equation is correctly expressed. The reaction above is a combustion reaction of octane. All of the combustion reaction is known to be exothermic reactions that is they release heat as the reaction proceeds. Consequently, they have negative enthalpies.

leonid [27]

Answer:

Explanation:

The law of multiple proportions say that two elements, A and B, are able to combine with each other to form distinct compounds, the different masses of B that bind to a certain mass of A, are in relation of integers and simple numbers.

2SO₂  → S₂ + 2O₂

Mass S₂=2 . 32g= 64g

Mass 2O₂=4 . 16g=64g

∴ 64/64=1 ⇒ One produced 1.002 g S for every gram of O, the relation is 1:1

2SO₃ → S₂ + 3O₂

Mass S₂=2 . 32g= 64g

Mass 3O₂=6 . 16g=96g

∴ 64/96= 2/3 ⇒ It is produced 0.668 g S for every gram of O, the relation is 2:3.

To sum up, these results are consistent with the law of multiple proportions because the results are integers and simple numbers.

I hope I help you!
