6.2 atm of N2O5 gas is at equilibrium with a 0.53 M N2O5 aqueous solution. What is the Henry’s Law constant of N2O5? Answer in M/atm. Do not type units. Do not use scientific notation.

The EPA discharge standard of nitrate (NO3-) is 24 mg/L. (The nitrate standard is complicated, but this is a good number to use.) A bottled tea factory is applying for a permit to discharge 12,000 L of 85 mg/L nitrate solution into a pond with initial volume 48,000 L that has essentially 0 nitrate. Should the permit be issued? The concentration of nitrate in the pond after discharge is calculated to be [final]. The permit is [status] because the concentration of nitrate in the pond after discharge will [reason] the standard.  

Which of the following are structural modifications to increase surface area for more absorption in the small intestine?

The reaction of 55.0 g methylamine (CH3NH2) with excess acetic acid (C2H4O2) produces metylacetamide (CH3NH2) and water: CH3NH2 + C2H4O2 –> C3H7NO + H2O. The reaction has an experimental yield of 76 g methylacetamide. What is the percent yield of metylacetamide? Answer in % to the ones place.  Use these molecular masses: Molecular Masses Compound Molecular Mass (g/mol) methylamine 31.0 acetic acid 60.0 methylacetamide 73.0 water 18.0
