- Complete and balance the following combustion reactions. Assume that each hydrocarbon is converted completely to carbon dioxide and water. (a) Propane + O2 (b) Octane + O2 (c) Cyclohexane + O2 (d) 2-Methylpentane + O2arrow_forwardUsing a table of average bond enthalpies. Table 6.2 ( Sec. 6-6b), estimate the enthalpy change for the industrial synthesis of methanol by the catalyzed reaction of carbon monoxide with hydrogen.arrow_forwardCream of tartar is a white powder sometimes used in baking. (It's what separates a tangy, chewy snickerdoodle from an ordinary cinnamon-coated sugar cookie. The acid in the cream of tartar gives snickerdoodles their distinctive tangy flavor, and the chew happens because cream of tartar prevents sugar in the cookie dough from crystalizing into crunchiness. Allrecipies.com) Cream of tartar (KHC4H4O6) is the conjugate base salt of tartaric acid (shown to the right). The Ka for another similar acid is 8.7×10-3. What is the standard Gibb's free energy (in kJ/mol) for the dissociation of that other acid?arrow_forward
- (HC(CH₂), CO₂) is 9.33 × 106. x Calculate the pH of a 2.8 M solution of trimethylacetic acid. Round your answer to 1 decimal place. The acid dissociation constant K of trimethylacetic acid pH = 0 X 5arrow_forwardDraw the product formed when the Lewis acid (CH;CH),C* reacts with each Lewis base: (a) H20; (b) CH3OH; (c) (CH3)20; (d) NH3; (e) (CH3)2NH.arrow_forwardMajor product and reactantsarrow_forward
- Write the Keq for the following reaction: N2(g)+3H2(g)~2NH3(g)arrow_forwardDraw Lewis structures and condensed structural formulas for the four alcohols with the molecular formula C4H10O. Classify each alcohol as primary, secondary, or tertiary. (Hint: First consider the connectivity of the four carbon atoms; they can be bonded either four in a chain or three in a chain with the fourth carbon as a branch on the middle carbon. Then consider the points at which the iOH group can be bonded to each carbon chain.)arrow_forwardSalicylic acid, HOC6H4CO2H, and its derivatives have been used as pain relievers for a long time. Salicylic acid occurs in small amounts in the leaves, bark, and roots of some vegetation (most notably historically in the bark of the willow tree). Extracts of these plants have been used as medications for centuries. The acid was first isolated in the laboratory in 1838. (a) Both functional groups of salicylic acid ionize in water, with Ka = 1.0 ×× 10−3 for the—CO2H group and 4.2 ×× 10−13 for the −OH group. What is the pH of a saturated solution of the acid (solubility = 1.8 g/L). (b) Aspirin was discovered as a result of efforts to produce a derivative of salicylic acid that would not be irritating to the stomach lining. Aspirin is acetylsalicylic acid, CH3CO2C6H4CO2H. The −CO2H functional group is still present, but its acidity is reduced, Ka = 3.0 ×× 10−4. What is the pH of a solution of aspirin with the same concentration as a saturated solution of salicylic acid (See Part a).arrow_forward
