Giovanna vaporized 5.00 grams of
sulfur using a bunsen burner and
added it to a flask filled with air.
Three possible reactions for this
experiment are:

Reaction I
S+ O2 SO2

Reaction II
2S+ 302 → 2SO3

Reaction III
5S+3N2 → S5N6

What is the theoretical yield of
SO₂ produced in Reaction I from
5.00 grams of sulfur?
10.0 g SO₂
12.5 g SO₂
0.156 g SO₂
