Due to substantial increases in prices in Country A, the real income level of the population in Country A decreases. Show on a diagram how the decrease in the income level in Country A will affect the demand for meat, which is a normal good. Also indicate how the equilibrium price and equilibrium quantity of meat will change in Country A. The direction of any changes should be clearly indicated using arrows.
Propose structure for molecules that fit the following descriptions:
A. C2H4O containing an aldehyde functional group
B. C3H6O2 containing a carboxylic acid functional group
Calculate the standard enthalpy of formation of carbon disulfide (CS2) from
its elements, given that
C(graphite) + O2(g) ⟶ CO2(g) ∆H°rxn = - 393.5 kJ/mol
S(rhombic) + O2(g) ⟶ SO2(g) ∆H°rxn = - 296.4 kJ/mol
CS2 (l) + 3O2(g) ⟶ CO2(g) + 2SO2(g) ∆H°rxn = - 1073.6 kJ/mol

Jamylla and Janylla are on a hike. Both hikers begin a trip by walking, the first leg A: 2.65 km, 140° from their base camp, on their second leg B: 4.77 km, 252° and to complete their final leg C: 3.18 km, 332°. What is the magnitude and direction of their final position from their base camp? Apply polygon method and component method and compare their results. (calculus based)
