• Respiration is one of the most common chemical reactions on earth. It includes the oxidation of glucose
(CsH1206) into carbon dioxide and water with the release
of approximately 2900 kJ of energy when one mole of
glucose is broken down according to the following
balanced equation:
C6H12O6 + 602 → 6CO2 + 6H2O + 2900 kJ mol-1
Then, upon the reaction of 25 grams of glucose with 40
grams of oxygen: 0,
- What is the limiting reactant?
- What mass of carbon dioxide formed?
- What is the weight left of excess reactant?
How much energy is released upon reaction of the
given amounts of glucose and oxygen?
(Atomic weights = 12.9 = 16 and H = 1 g/mol)​

11. phosphorus-32 is radioactive and has a half life of 14 days. how much of a 124 mg sample of phosphorus-32 is present after 56 days? a) 7.75 mg b) 15.5 mg c) 31.0 mg d) 62.0 mg

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap
