Question
1) This is a classic combustion reaction: C 6 H 14 O 4 (g) + O 2 (g) CO 2 (g) + H 2 O
1) This is a classic combustion reaction:
C6H14O4 (g) + O2 (g) CO2 (g) + H2O (g)
Balance this equation, and determine the volume of carbon dioxide (in L) produced if 2.24 grams of C6H14O4 are consumed in the presence of an excess of oxygen, at a temperature of 210.2C and a pressure of 1.121 atm
2) Consider the following reaction:
Al2(CO3)3 (s) + HCl (aq) AlCl3 (aq) + H2O (l) + CO2 (g)
Balance the equation, and find the volume (in L) of carbon dioxide generated at standard temperature and pressure (273.15 K, 1.00 atm) from 7.28 grams of aluminum carbonate reacted.
3) You conduct the collection of O2 gas over water in the following reaction:
2 Cu2O 4 Cu + O2
The volume of your collection is 214.3 mL; the pressure of the gas in the collection chamber is 0.984 atm, and the temperature of the gas and the water in the collection chamber is 18.0C. The vapor pressure of water at this temperature is 0.0204 atm. What mass of Cu2O was decomposed?
