- Which is the stronger acid, HClO4 or HBrO4? Why?arrow_forwardSodium perchlorate, NaClO4, is produced by electrolysis of sodium chlorate, NaClO3. If a current of 2.50 103 A passes through an electrolytic cell, how many kilograms of sodium perchlorate are produced per hour?arrow_forwardWhat mass of CaH2 is necessary to react with water to provide enough hydrogen gas to fill a balloon at 20 C and 0.8 arm pressure with a volume of 4.5 L? The balanced equation is: CaH2(s)+2H2O(l)Ca(OH)2(aq)+2H2(g)arrow_forward
- The amount of sodium hypochlorite in a bleach solution can be determined by using a given volume of bleach to oxidize excess iodide ion to iodine, because the reaction goes to completion. The amount of iodine produced is then determined by titration with sodium thiosulfate, Na2S2O3, which is oxidized to sodium tetrathionate, Na2S4O6. Potassium iodide was added in excess to 5.00 mL of bleach (density = 1.00 g/mL). This solution, containing the iodine released in the reaction, was titrated with 0.100 M Na2S2O3. If 34.6 mL of sodium thiosulfate was required to reach the endpoint (detected by disappearance of the blue color of the starch iodine complex), what was the mass percentage of NaClO in the bleach?arrow_forwardWrite a balanced equation for the reaction of elemental strontium with each of the following:(a) oxygen(b) hydrogen bromide(c) hydrogen(d) phosphorus(e) waterarrow_forward(c) Suggest how the following boron species could be prepared, showing any intermediates. -B(OH)2 B(OH)2arrow_forward

(b) What is the oxidation state of magnesium in MgO? (c) Which species is oxidized? (d) Which species is reduced? (e) Name the oxidizing agent.arrow_forwardThe elements sodium, aluminum, and chlorine are in the same period.(a) Which has the greatest electronegativity?(b) Which of the atoms is smallest?(c) Write the Lewis structure for the simplest covalent compound that can form between aluminum and chlorine.(d) Will the oxide of each element be acidic, basic, or amphoteric?arrow_forwardWhat is a disproportionation reaction, and which of thefollowing fit the description?(a) I₂(s) +KI(aq) →KI₃(aq)(b) 2ClO₂(g) +H₂O(l) →HClO₃(aq) +HClO₂(aq)(c) Cl₂(g)+ 2NaOH(aq)→ NaCl(aq)+ NaClO(aq)+ H₂O(l)(d) NH₄NO₂(s)→ N₂(g) +2H₂O(g)(e) 3MnO₄²⁻(aq)+ 2H₂O(l) →2MnO₄(aq) +MnO₂(s) +4OH(aq)(f) 3AuCl(s) →AuCl₃(s)+ 2Au(sarrow_forward
- Write a balanced equation for each of the following: (a) A characteristic reaction of Group 1A(1) elements: chunks of sodium react violently with water to form hydrogen gas and sodium hydroxide solution. (b) The destruction of marble statuary by acid rain: aqueous nitric acid reacts with calcium carbonate to form carbon dioxide, water, and aqueous calcium nitrate. (c) Halogen compounds exchanging bonding partners: phosphorus trifl uoride is prepared by the reaction of phosphorus trichloride and hydrogen fl uoride; hydrogen chloride is the other product. The reaction involves gases only.arrow_forwardWhich of the following statements are true?(a) Both nitrogen and phosphorus can form a pentafluoridecompound.(b) Although CO is a well-known compound, SiO does notexist under ordinary conditions.(c) Cl2 is easier to oxidize than I2.(d) At room temperature, the stable form of oxygen is O2,whereas that of sulfur is S8.arrow_forwardThe physical properties of D2O differ from those of H2Obecause(a) D has a different electron configuration than O.(b) D is radioactive.(c) D forms stronger bonds with O than H does.(d) D is much more massive than H.arrow_forward
