Equal volumes of H2 and O2 are placed in a balloon and then ignited. Assuming that the reaction goes to completion, which gas will remain in excess?
2H2 + O2 → 2H2O
Use the integrated rate law method to determine the rate constant for the data collected for the reaction:
what is the pH after the addition of 2.7*10-2 moles of KOH to 3.6*10-2 moles HCl if the resulting solution volume is 150mL
you have two flasks of equal volume. flask a contains h2at 0degc and 1 atm pressure. flask b contains co2 gasat 0degc
For [Co(en)(NH3)2Cl2]ClO4 identify the coordination number of cobalt, the coordination geometry for cobalt, the oxidation number of cobalt, the number of unpaired electrons
At a constant pressure of 97.0 atm, calculate the work done by the gas when the volume decreases from 87.0 L to 19.0 L. (make sure the sign and units are correct)

Calculate the volume of a sample of carbon monoxide at -21°C and 359 torr if it occupies 3.65 L at 298 K and 758 torr.
Four liters of water are equilibrated with a gas mixture containing carbon dioxide at a partial pressure of .3 atm. Henry's law constant for H2CO3* solubility is 2.0 g/L-atm.
Compare the natural chemistry that takes place in the environment with the chemistry that takes place due to man made factors like pollution. Discuss the effect of pollution at the local, regional, national, and global level.
a sample of gas at 77 degreees celsius and 1.03 atm occupies a volume of 2.02L. What volume would this gas occupy at 107 degreees celcius and 0.789 atm.
