Chemistry & Chemical Reactivity
- The carbon dioxide exhaled in the breath of astronauts is often removed from the spacecraft by reaction with lithium hydroxide 2LiOH(s)+CO2(g)Li2CO3(s)+H2O(l) Estimate the grams of lithium hydroxide required per astronaut per day. Assume that each astronaut requires 2.50 103 kcal of energy per day. Further assume that this energy can be equated to the heat of combustion of a quantity of glucose, C6H12O6, to CO2(g) and H2O(l). From the amount of glucose required to give 2.50 103 kcal of heat, calculate the amount of CO2 produced and hence the amount of LiOH required. The H for glucose(s) is 1273 kJ/mol.arrow_forwardWhat is Hrxn for reaction of iron(III) oxide and carbon monoxide to give iron metal and carbon dioxide gas? Use the following reactions: 4Fe(s)+3O2(g)2Fe2O3(s)H=1648.4kJ4CO(g)+O2(g)2CO3(g)H=565.98kJarrow_forwardMany over-the-counter antacid tablets are now formulated using calcium carbonate as the active ingredient, which enables such tablets to also be used as dietary calcium supplements. As an antacid for gastric hyperacidity, calcium carbonate reacts by combining with hydrochloric acid found in the stomach, producing a solution of calcium chloride, converting the stomach acid to water, and releasing carbon dioxide gas (which the person suffering from stomach problems may feel as a “burp”). Write the unbalanced chemical equation for this process.arrow_forward
- The presence of carbon dioxide.arrow_forward36. Balance these ionic redox equations using the ion- electron method. These reactions occur in basic solution.arrow_forwardDecide whether a chemical reaction happens in either of the following situations. If a reaction does happen, write the chemical equation for it. Be sure your chemical equation is balanced and has physical state symbols. A strip of solid silver metal is put into a beaker of 0.020M Sn(NO3)2 solution.arrow_forward
- Write a balanced chemical equation for each of the following neutralization reactions: (a) Chloric acid neutralizes a strontium hydroxide solution. (b) Phosphoric acid neutralizes a sodium hydroxide solution.arrow_forward(A) if both sentences are true,(B) if both sentences are false,(C) if the first sentence is true but the second is false, and(D) if the first sentence is false but the second is true. 1. In a redox reaction, the oxidation number of iron changed from +2 to +3; thus, sulfur is a reducing agent. In a redox reaction, the oxidation number of nitrogen was unchanged; thus, nitrogen is an oxidant. 2. In a redox reaction, the reducing agent is oxidized and it gains electrons. In a redox reaction, the oxidizing agent is reduced and it gains electrons. 3. Bending stress is also known as flexural stress. The test used in observing the mechanical strength of chocolate is the three-point bend test. 4. The flexural strength of materials may be expressed in Pascals. Magnesium is more reactive than silver; therefore, magnesium corrodes faster than silver with the aid of air, oxygen, and sea water.arrow_forward(1) To analyze the concentration of chloroform precursors, or natural organic matter, in a drinking water sample, which of the following instruments should be used? (A) TOC analyzer (B) GC (C) AA (D) IC (2) To analyze the concentration of cadmium (Cd) in a water sample, which of the following instruments should be used? (A) TOC analyzer (B) GC (C) AA (D) LC (3) To analyze the concentration of the chlorine residual in a water sample, which of the following instruments should be used? (A) TOC analyzer (B) GC (C) AA (C) AA (D) IC (4) To identify an unknown organic compound in drinking water, which of the following instruments should be used? (A) TOC analyzer (B) GC (D) IC (E) DPD Method (C) conductivity (E) GC/MS (5) To evaluate the quality of a drinking water sample, which of the following parameters may NOT be tested? (A) TSS (B) turbidity (D) TOC (E) coliformsarrow_forward
- Permanganate Ions are reacted with Iron(II) in the presence of an acid to produce Manganese(II) ions, Iron(III) ions, and water. Write the balanced chemical equation for this process.arrow_forwardAqueous hydrogen fluoride (hydrofluoric acid) is used to etch glass and to analyze minerals for their silicon content. Hydrogen fluoride will also react with sand (silicon dioxide).(a) Write an equation for the reaction of solid silicon dioxide with hydrofluoric acid to yield gaseous silicon tetrafluoride and liquid water.(b) The mineral fluorite (calcium fluoride) occurs extensively in Illinois. Solid calcium fluoride can also be prepared by the reaction of aqueous solutions of calcium chloride and sodium fluoride, yielding aqueous sodium chloride as the other product. Write complete and net ionic equations for this reaction.arrow_forwardA key step in balancing chemical equations is correctly identifyingthe formulas of the reactants and products. For example,consider the reaction between calcium oxide, CaO(s),and H2O(l) to form aqueous calcium hydroxide. (a) Write abalanced chemical equation for this combination reaction,having correctly identified the product as Ca(OH)2(aq).(b) Is it possible to balance the equation if you incorrectly identifythe product as CaOH(aq), and if so, what is the equation?arrow_forward
