About 5 billion kilograms of benzene, C6H6, are made each year. Benzene is used as a starting material for many other compounds and as a solvent (although it is also a carcinogen, and its use is restricted). One compound that can be made from benzene is cyclohexane, C6H12. C6H6() + 3 H2(g) C6H12() rH = 206.7 kJ/mol-rxn; rS = 361.5 J/K mol-rxn Is this reaction predicted to be product-favored at equilibrium at 25 C? Is the reaction enthalpy- or entropy-driven?
1.1 It is well-known that te emission of greenhouse gasses such as carbon dioxide presents a very grave threat to the environment. Attempts are ongoing to absorb this gas by several means. One such approach involves the use of vegetation, as plants utilize the gas by means of photosynthesis. One such plant , which has shown great promise, is the "Spekboom" It has been estimated that fully-grown Spekboom can absorb 3.8 tonnes of carbon per hectare of plants per year. If the system is fully functional, South Africa can generate 234.5 x 109 kWh of electricity per year. Assume that 1559 pounds of CO2 is emmited per year per Megawatt-hour of electricity generated in the country. Determine, by means of the use of conversion factors, how many square kilometres of Spekboom could theoretically absorb all of this carbon dioxide ? 1.2 Consider the molecule, ClPO2 (The Phosphorus atom is the central atom) 1.2.1 Draw the 3-D Lewis dot structure of the molecule, including all possible resonance…

Determine the percentage of each element in the following hydrocarbon fuels on amass basis: a) Benzene (C6H6), b) Ethane (C2H6), c) Methanol (CH3OH), d) Butane (C4H10), e)Ethanol (C8H5OH), f) Octane (C8H18), g) Dodecane (C12H26), and h) (CH4).
Gasoline is composed primarily of hydrocarbons, includingmany with eight carbon atoms, called octanes. One ofthe cleanest–burning octanes is a compound called 2,3,4-trimethylpentane, which has the following structural formula The complete combustion of one mole of this compoundto CO21g2 and H2O1g2 leads to ΔH° = -5064.9 kJ.(a) Write a balanced equation for the combustion of1 mol of C8H181l2. (b) By using the information inthis problem and data in Table 5.3, calculate ΔHf° for2,3,4-trimethylpentane.
