Get started for freeThe mass percent of in a seawater sample is determined by titrating 25.00 mL of seawater with solution, causing a precipitation reaction. An indicator is used to detect the endpoint, which occurs when a free ion is present in the solution after all the has reacted. If 53.63 mL of 0.2970 M is required to reach the endpoint, what is the mass percent of 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?
For the following aqueous reactions, complete and balance the molecular equation and write a net ionic equation:
(a) Manganese(II) sulfide + hydrobromic acid
(b) Potassium carbonate + strontium nitrate
(c) Potassium nitrite + hydrochloric acid
(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?
