Reaction between sulphur and oxygen..?

Question

write a balanced equation to show how sulphur burns to form sulphur dioxide?

is the correct answer S O2 --> SO2

or S8 8O2 --> 8O2?

thanks! :D

Answer 1

S + O2 --->  SO2

Is the correct equation.

It can produce the trioxide which is the precursor to sulphuric acid, but this often requires a lot more energy and a catalyst.

2S + 3O2  --->  2 SO3

Answer 2

when it reacts with oxygen, they both form an oxide called sulfur dioxide
