Before balancing the chemical reaction, let’s first write the chemical formula of each of the compounds involved in the reaction.
Sulfur : S (s)
Which formula equation represents the burning of sulfur to produce sulfur dioxide?
a. S (s) + O2 (g) → SO2 (g)
b. 2 H2 (g) + S (s) + 3 O2 (G) → H2O (l) + 2SO2 (g)
c. 4 FeS2 (s) + 11 O2 (g) →2 Fe2O3 (s) +8 SO2 (g)
d. 2 SO2 (g) + O2 (g) → V2O5 (s)+ 2 SO3 (g)
