The volume of a gas bag was found to be 840 mL at a temperature of 25 degrees C and a pressure of 734 torr. What would be its volume at STP?
If the volume of the gas sample is decreased to 15.3 L holding the temp constant, the average molecular speed will increase, decrease or remain the same?
The RUBISCO catalyzed reaction is: a. Exergonic, because Ribulose-,5-biphosphate has enormous energy charge built up from previous phosphorylations
You carry out a titration of a pure weak triprotic acid and only see two major pH jumps. One at 10.0 mL and one at 15.0 mL. At what volume is the other equivalence point
using henderson hasselbalch calculate the ph of .5 L of 2.0M solution of nitrous acid, HNO2 that also contains 140g of nano2 (MM=70g/mol)
For the reaction Cu(s) + 2 Fe3+(aq) Cu2+(aq) + 2 Fe2+(aq), the equilibrium constant is Kc = 3.7×10^14 at 25 oC. Suppose that excess Cu(s) is added to 1.0 L of 0.015 mol L^-1 Fe(NO3)3(aq), with no change in volume. What is the equilibrium concent..

In the 1980s, there was an international agreement to destroy all stockpiles of mustard gas, ClCH2CH2SCH2CH2Cl. When this substance contacts the moisture in eyes, nasal passages, and skin
The mole fraction of water in the product gas is monitored and found to have the value calculated in part (a) for the first 10hours of operation, but then it begins to increase. What is the most likely cause of the increase? If the process continu..
Look carefully at the frontier MOs of the diatomic molecule, BF and determine the most basic site. Based on your observations, predict the structure that results when H+ adds to BF.
The next day you notice that some of the gas has leaked out. The pressure and temperature remain the same, but the volume has changed to 12.0 . How many moles of gas () remain in the cylinder
