A) identify the limiting reagent and predict how many grams of sodium sulfate are produced when 2.0g of sulfur reacts with 3.0g of oxygen and 4.0g of sodium hydroxide according to the following chemical equation 2 S(s)+3O2(g)+4NaOH(aq)-----> 2 Na2SO4(aq)+ 2H2O(l)

B) The concentration of chlroide ion (CI-) in an aqueus salt solution can be determined by titrating with a solution of AgNO3-. In this Titration, the following reaction occurs:

AgNO3(aq)+NaCl(aq)--->AqCl(s)+NaNO3(aq)

1) please write out the ionic equations for this reaction

2) What is the concentraion of Cl- (aq) in a 100,0 mL sample of a salt solution if 24,1 mL of 0.100 M AgNO3(aq) are needed to react with all the Cl-(aq) in sample?
