Calculate AH for the reaction: 6 C(s) + 6 H2(g) + 3 O2(g) → C6H12O6(s) using the following three equations: C(s) + O2(g) → CO2(g) H2(g) + O2(g) → H₂O(1) C6H12O6(s) + 6 O2(g) → 6 CO2(g) + 6 H2O(1) AH°=-285.8 kJ AH° = -285.8 kJ AH°=-2803.02 kJ

Calculate the Enthalpy Change (ΔH) from average bond energies, which have been listed below in KJ/mol, for the following reaction and identify the nature of the reaction: CH3COOH + CH3OH → CH3COOCH3 + H2O [C‒H: 413; C‒C: 347; C=O: 745; C=C: 614; Cl‒Cl: 239, C‒O: 358; O‒H: 467]

Chemically and physically describe the combustion of methane CH4 (g) + 2 O2 (g) → CO2 (g) + 2 H20 (g)

Classify the following compounds as primary (1o), secondary (2o), or tertiary (3o) alcohol

(a) When the metallic element sodium combines with the nonmetallic element bromine, Br2(l), how can you determine the chemical formula of the product? How do you know whether the product is a solid, liquid, or gas at room temperature? Write the balanced chemical equation for the reaction. (b) When a hydrocarbon burns in air, what reactant besides the hydrocarbon is involved in the reaction? What products are formed? Write a balanced chemical equation for the combustion of benzene C6H6(l), in air.

C7H12 (l) + ? O2(g) → 7 CO2(g) + 6 H2O(g)

Hydrogen cyanide can be catalytically reduced with hydro-gen to form methylamine. Use Lewis structures and bond ener-gies to determine ΔH°ᵣₓₙ for HCN(g)+2H₂(g)→CH₃NH₂(g)

Be sure to answer all parts. Determine Angas for each of the following reactions: (a) MgCO3(s) → MgO(s) + CO2(g) mol (b) 2 H2(g) + O2(g) → 2 H₂O(l) mol (c) HNO3(1) + CIF(g) → CIONO2(g) + HF(g) mol

Ethanol, C₂H60, is most often blended with gasoline - usually as a 10 percent mix - to create a fuel called gasohol. Ethanol is a renewable resource and ethanol-blended fuels, like gasohol, appear to burn more efficiently in combustion engines. The combustion of one mole of ethanol releases 326.7 kcal of energy. The combustion of one mole of 2-methylheptane, C8H18, releases 1.306 × 10³ kcal of energy. How much energy is released during the complete combustion of 405 grams of 2- methylheptane? kcal Assuming the same efficiency, would 405 grams of ethanol provide more, less, or the same amount of energy as 405 grams of 2-methylheptane? more less the same amount Retry Entire Group 9 more group attempts remaining
