What is the pressure in the cylinder below just due to the argon (Ar) gas? Enter only the number part of the value without including units (for example, you would enter 450 rather than 450 torr)
One method for favoring the formation of an ester is to add excess acetic acid. Suggest another method, involving the right-hand side of the equations, that will favor the formation of an ester.
If the sample of the complex ion compound that you prepared had not thoroughly dried, but contained traces of water or ethanol would this make your value of x too high or too low? Or would it not affect your results at all? Explain.
Solutions of sodium carbonate and silver nitrate react to form solid silver carbonate and a solution of sodium nitrate. A solution containing 8.00 g of sodium carbonate is mixed with one containing 4.75 g of silver nitrate.
