- When carbon dioxide dissolves in water it reacts to produce carbonic acid, H2CO3(aq), which can ionize in two steps. H2CO3(aq)HCO3(aq)+H+(aq)Kc1=4.2107HCO3(aq)CO32(aq)+H+(aq)Kc2=4.81011 Calculate the equilibrium constant for the reaction H2CO3(aq)CO32(aq)+2H+(aq)arrow_forwardThe reaction of calcium hydride, CaH2, with water can be characterized as a Lewis acid-base reaction: CaH2(s)+2H2O(l)Ca(OH)2(aq)+2H2(g) Identify the Lewis acid and the Lewis base among the reactants. The reaction is also an oxidation-reduction reaction. Identify the oxidizing agent, the reducing agent, and the changes in oxidation number that occur in the reaction.arrow_forwardThe 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; ClO- is reduced to Cl-. The amount of iodine produced by the redox reaction is determined by titration with sodium thiosulfate, Na2S2O3; I2 is reduced to I-. The sodium thiosulfate is oxidized to sodium tetrathionate, Na2S4O6. In this analysis, potassium iodide was added in excess to 5.00 mL of bleach (d=1.00g/cm3) . If 25.00 mL of 0.0700 M Na2S2O3 was required to reduce all the iodine produced by the bleach back to iodide, what is the mass percent of NaClO in the bleach?arrow_forward
- Which is the stronger acid, H2SO4 or H2SeO4? Why? You may wish to review the Chapter on acid-base equilibria.arrow_forwardXenon trioxide, XeO3, is reduced to xenon in acidic solution by iodide ion. Iodide ion is oxidized to iodine, I2. Write a balanced chemical equation for the reaction.arrow_forwardPhosphate buffers are important in regulating the pH of intracellular fluids. If the concentration ratio of H2PO4/HPO42 in a sample of intracellular fluid is 1.1: 1, what is the pH of this sample of intracellular fluid? H2PO4(aq)HPO42(aq)+H+(aq)Ka=6.2108arrow_forward
- Data are given in Appendix 1 for white phosphorus, P4(s). P4(g) has the following thermodynamic values: Hf=58.9kJ/mol , S=280.0J/kmol . What is the temperature at which white phosphorus sublimes at 1 atm pressure?arrow_forwardThe molecular weight of sperm whale myoglobin is 17.8 kDa.17.8 kDa. The myoglobin content of sperm whale muscle is about 80 g · kg−1.80 g · kg−1. In contrast, the myoglobin content of some human muscles is about 8 g · kg−1.8 g · kg−1. Compare the amounts of O2O2 bound to myoglobin in human muscle and in sperm whale muscle. Assume that the myoglobin is saturated with O2,O2, and that the molecular weights of human and sperm whale myoglobin are the same. How much O2O2 is bound to myoglobin in human muscle? How much O2O2 is bound to myoglobin in whale muscle? The amount of oxygen dissolved in tissue water at 37°C37°C is about 3.5×10−5 M.3.5×10−5 M. What is the ratio of myoglobin‑bound oxygen to dissolved oxygen in the tissue water of sperm whale muscle?arrow_forwardPlease Write the chemical equations for the following processes in the image below.arrow_forward
