The mass percent of Cl- in a seawater sample is determined by titrating 25.00 mL of seawater with AgNO3 solution, causing a precipitation reaction. An indicator is used to detect the endpoint, which occurs when a freeAg+ ion is present in the solution after all theCl- has reacted. If 53.63 mL of 0.2970 MAgNO3 is required to reach the endpoint, what is the mass percent of Cl- in the seawater (d of seawater = 1.024 g/mL)?

Iron reacts rapidly with chlorine gas to form a reddish brown, ionic compound (A), which contains iron in the higher of its two common oxidation states. Strong heating decomposes compound A to compound B, another ionic compound, which contains iron in the lower of its two oxidation states. When compound A is formed by the reaction of 50.6 g of Fe and 83.8 g of Cl2 and then heated, how much compound B forms?

(d) Calcium hydroxide + nitric acid

(e) Barium acetate + iron(II) sulfate

(f) Zinc carbonate + sulfuric acid

(g) Copper(II) nitrate + hydrosulfuric acid

(h) Magnesium hydroxide + chloric acid

(i) Potassium chloride + ammonium phosphate

(j) Barium hydroxide + hydrocyanic acid

Limestone (CaCO3) is used to remove acidic pollutants from smokestack flue gases. It is heated to form lime (CaO), which reacts with sulfur dioxide to form calcium sulfite. Assuming a 70.% yield in the overall reaction, what mass of limestone is required to remove all the sulfur dioxide formed by the combustion of 8.5104 kg of coal that is 0.33 mass % sulfur?

Why must every redox reaction involve an oxidizing agent and a reducing agent?
