A fuel gas containing methane and ethane is burned with air infurnace, producing a stack gas at 300C and 105kPa(absolute). The stack gas contains C02 at a partial pressure of 80 mm Hg and no CO,O2, methane or ethane. Calculate the mole fraction of methane in the fuel and the dew point temperature of the stack gas.

Compare the amount of .200 moles of KOH needed to neutralize 50 mL of .200 moles of HNO3 with the amount of .200 moles of KOH needed to neutralize 50 mL of .200 moles of CH3COOH. Is the volume of KOH more, less or the same.
the main product of the reaction is 1-iodo-1,1-diphenylethane. Propose a plausible mechanism that accounts for the formation of this product. Use arrows to indicate electron flow in each step.
From the examples you state, select one acid, one base, and one salt and describe specifically how and where they are used in therapeutic processes. Define a buffer and explain how a buffer works.
