Carbon dioxide 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 carbon dioxide concentration in the atmosphere, but carbon dioxide is also the end product of metabolism. a.Using glucose (C6H12O6) as an modelof food, and combustion as a model for how our bodies “burn” food to create energy, calculate the annual human production of carbon dioxide in kg. Assume that each person consumes 5.0...

Aqueous glucose (C6H12O6) combines with oxygen gas during metabolism, producing carbon dioxide gas and liquid water. A. Write a balanced chemical equation (including physical states) for the reaction described above. B. If 0.125 moles of glucose are metabolized, how many moles of carbon dioxide are formed? C. If 0.125 moles of glucose are metabolized, how many moles of water are formed? Zinc reacts with aqueous sulfuric acid, in a single displacement reaction. 1.

on average, and adult will expend about 1,800 kilocalories per day. Processing a single ATP molecule produces about 1.2 X 10-23 kcal. How many ATP molecules must be processed each day to maintain energy levels?

Americans drive about 4.0 x 10^9 miles per day, and their cars get an average of 20 miles per gallon of gas used. For each kilogram of gasoline used, about 3 kg of carbon dioxide is produced. How many kilograms of CO2 are emitted into the atmosphere by cars in the US each day? [1 gal = 3.5 kg]

C) In one long stoichiometry problem calculate the kilograms of carbon dioxide produced each day by all the coal power plants in the world, There are 2300 coal power plants in operation. The average plant can make 547 Mw per minute, however they never work at full capacity. The average plan operates at 70% capacity. Coal is mostly elemental carbon (C) that undergoes a synthesis reaction with oxygen gas to make carbon dioxide gas. One metric ton of coal makes...

People in confined spaces like those of space vehicles are at risk of carbon dioxide intoxication due to build-up of the gas. In a space shuttle, the carbon dioxide expelled by the crew is removed from the air by a reaction within canisters of lithium hydroxide. The reaction is, LiOH + CO2 → Li2CO3 + H2Oa) How many moles of LiOH can be used to remove the CO2 gas expelled by each crew if on the average, each exhales about...

2. An average human has about 67% water by mass. A 75.0 kg person suffering from hypothermia has a body water temperature of 33.5°C and needs to raise this to the normal body temperature of 37.0°C. a) How many grams of sucrose, C12H220(S), must be metabolized (use this as a simple combustion reaction with gaseous oxygen, producing liquid water and gaseous carbon dioxide)? g sucrose b) What volume of air (L) with a 1 atm total pressure and a partial...

32. (Bonus) Americans combined drive about 4.0 x 109 kilometers a day and get an average of 20 miles per gallon of gasoline. For each kilogram of gasoline that is burned about 3 kg of carbon dioxide (CO2) are produced. With the density of gasoline as 0.93 g/cm3, how many kg of CO2 are emitted by U.S.cars into the atmosphere each minute? (1 gallon 3.7854 L, 1 mile 1.609 km) 4.7 x 109 kg CO2/min 5.47 x 107 kg CO2/min...

The average adult consumes approximately 11,700 kJ per day. Assuming that the metabolic pathways leading to ATP synthesis operate at 50% thermodynamic efficiency, about 5850 kJ ends up in the form of synthesized ATP. Imagine that creatine phosphate, rather than ATP, is the universal energy carrier molecule in the human body. Assume that the cellular concentrations of creatine phosphate, creatine, and phosphate are 19.7 mM, 1.97×10-3 mM, and 5.80 mM, respectively. Calculate the weight of creatine phosphate that would need...
