classification of Sulfur Dioxide
Sulfur Dioxide, (SO2), is an inorganic compound, a heavy colorless poisonous gas.
Sulfur dioxide has a pungent, irritating odor, familiar as the smell of a just-struck match. It is produced in huge quantities in an intermediate setup. Occurring in nature in volcanic gases and in solution in the waters of some warm springs, sulfur dioxide usually is prepared industrially by the burning in air or oxygen of sulfur or such compounds of sulfur as iron pyrite or copper pyrite.
In the atmosphere, it can combine with water vapor to form sulfuric acid, a major component of acid rain. In the laboratory the gas may be prepared by reducing sulfuric acid (H2SO4) to sulfurous acid (H2SO3), which decomposes into water and sulfur dioxide, or by treating sulfites (salts of sulfurous acid) with strong acids, such as hydrochloric acid, again forming sulfurous acid.
Sulfur dioxide can be liquefied under moderate pressures at room temperatures; the liquid freezes at −73° C (−99.4° F) and boils at −10° C (14° F) under atmospheric pressure. Although its chief uses are in the preparation of sulfuric acid, sulfur trioxide, and sulfites, sulfur dioxide also is used as a disinfectant, a refrigerant, a bleach, and a food preservative, especially in dried fruits.

If 18.0 grams of water were actually produced, what is the percent yield of the reaction between 4 g of hydrogen gas and 1.5 mol of oxygen gas?
The percent yield of the water is 33.3%.
What is the percent yield?We know that the reaction that takes place between hydrogen and oxygen to give water is; [tex]2H_{2} (g) + O_{2} (g) ----- > 2H_{2}O(g)[/tex]. We now need to find the number of moles of hydrogen = 4 g/2 g/mol = 2 moles
Now;
If 2 moles of hydrogen reacts with 1 moles of oxygen
We can see that oxygen is the limiting reactant in this case.
1 mole of oxygen produces 2 moles of water
1.5 moles of oxygen produces 1.5 * 2/1
= 3 moles of water
Then the theoretical yield of water = 3 moles * 18 g/mol = 54 g
