Given the following data NH3(g) → > N₂(g) + ³H₂(g) 2H₂(g) + O₂(g) →→ 2H₂O(g) calculate AH for the reaction ΔΗ = 46 kJ ΔΗ = -484 kJ 2N₂(g) + 6H₂O(g) →→30₂(g) + 4NH3(g)

Research studies have found that the price elasticity of demand for bread is equal to -0.40 and the price elasticity of demand of butter is equal to -1.13. Holding everything else constant, if the price of bread and the price of butter each increase by 10 percent: (a) Will the revenue from sales of bread increase or decrease? (b) Will the revenue from sales of butter increase or decrease?

Use and modify some/all the reactions provided to form the indicated overall reaction according to Hess' Law. • If a reaction is not used in your Hess' Law process, include that indication by multiplying the reaction by "0" • If no modification is needed and the reaction is applied as written below, include that indication by multiplying the reaction by "1" • Use whole numbers and simple fractions (such as "2" or "1/2", not 0.5) and negative signs (such as "-2") where needed Then calculate and report the enthalpy change (in kJ) for the overall reaction in the indicated blank, including units with your written value and rounded to 1 decimal place. Overall Reaction: CS2(1) + 302(g) → CO2(g) + 2SO2(g) Rxn # Reaction ΔΗ° (kJ) 1 C(s) → C(g) 716.67 2 C(s) + O2(g) → CO2(g) -393.5 3 3Fe(s) +202(g) → Fe3O4(s) -1118 4 C(s) + 2S(s) → CS2(1) 87.9 5 CH4(g) + O2(g) → CO₂(g) + H₂O(g) -882.0 6 S(s) + O2(g) → SO2(g) -296.8 N2(g) + 4H2(g) + Cl2(g) → 2NH4Cl(g) -629.1 7
