Document Summary
Please state any additional assumptions you made, and show all work. You are welcome to use a graphical method of solution if it is appropriate. 540 calories = 1 big mac (30%) calculate the ph for a 1-liter volume of pure water at 80 c to which you have dissolved 10-3 moles of h2s. The temperature of the final solution is at 80 c. Approximate values ( 0. 2 log units) will suffice. (10%) true/false. Mark each one of the following statements with either a. Water has an unusually high boiling point based on its molecular weight. A nano gram is equivalent to one-thousanths of a milligram. The third most common gas in the atmosphere is carbon dioxide. Non-carbonate hardness only exists in waters with alkalinities less than than their total hardness. Mass defects are directly proportional to nuclear binding energy. The guntelberg approximation says that activity coefficients are dependent on charge and ionic strenth, but not on ion size.
