Carbon dioxide (CO2) is the gas that is mainly responsible for global warming (the greenhouse effect). The burning of fossil fuels is a major cause of the increased concentration of CO2 in the atmosphere. Carbon dioxide is also the end product of metabolism. A general overall equation for this very complex process represents the degradation of glucose (C,H12O6) to carbon dioxide (CO2) and water (H20). C,H1206 + 602 → 6CO2 + 6H20 Using glucose as an example of food, calculate the annual human production of CO2 in grams, assuming that each person consumes 4.69 × 102 g of glucose per day. The world's population is 6.50 billion and there are 365 days in a year. x 10 Enter your answer in scientific notation.

Ethylene (C2H4) plays an important role in the ripening of certain fruits and vegetables. It is sometimes supplemented under controlled conditions at produce—processing facilities but is also produced naturally by many fruit-bearing plants. Although the actual process by which plants produce ethylene is a complex one, imagine that it is produced by the simple breakdown of glucose according to the equation: C6H12O6 (s) à 3 C2H4 (g) + 3 O2 (g) Given S°= 212.1 J/molK, DG°= -910.56 kJ/mol and DH°= -1274.5 kJ/mol for C6H12O6 (s). a.) Determine the sign of DS° for the reaction. b.) Calculate DS° for the reaction. c.) Using the tabulated DG° values in the appendix, calculate DG° for the reaction. d.) Above what temperature (in °C) is the reaction spontaneous? Hint: you will first have to calculate DH° using tabulated values.
Dry ice is solid carbon dioxide. Instead of melting, solid carbondioxide sublimes according to the equation:CO2(s) ------------>CO2(g) When dry ice is added to warm water, heat from the water causesthe dry ice to sublime more quickly. The evaporating carbon dioxide produces a dense fog often used to create special effects. In a simple dry ice fog machine, dry ice is added to warm water in a Styrofoam cooler. The dryice produces fog until it evaporates away, or until the water gets too cold to sublime the dry ice quickly enough. A small Styrofoam cooler holds15.0 L of water heated to 85°C. Use standard enthalpies of formation to calculate the change in enthalpy for dry ice sublimation, and calculate themass of dry ice that should be added to the water so that the dry ice completely sublimes away when the water reaches 25 °C. Assume no heat loss to the surroundings. (The ∆H°f for CO2(s) is -427.4 kJ/mol.)

Your lab partner accidentally mixed some sodium chloride with your sample of Epsom salts (M9SO,·7H,O). You want to make a standard solution of magnesium ion, and this is the only sample of a magnesium salt you have. To determine the amount of magnesium salt in the mixture, you heat 100.00 g to drive off the water of hydration and find that the anhydrous mixture has a mass of 73.25 g. What is the mass in grams of the original salt mixture that you must add to 1.000L of water to make a 0.1000 M solution of Mg2+ ion?
