The major air pollutant in coal-burning countries is a colorless, pungent gaseous compound containing only sulfur and oxygen. Chemical analysis of a 1.078g sample of this gas showed that it contained 0.540g of
sulfur and 0.538g oxygen. What is the empirical formula of this compound?
(Worked out fully)

H2so4(aq) + mg(s)—> mgso4(aq) +h2(g) which substance is the acid in the reaction?

To save time, you can approximate the initial mass of the solid to the nearest ±1 g. for example, if you are asked to add 14.3 g of copper, add between 13 g and 15 g. which of the following sets include two samples with an equal density? which all that apply below 15.4 g gold and 18.7 g silver 15.2 g copper and 50.0 g copper 20.2 g silver and 20.2 g copper 11.2 g gold and 14.9 g gold
