Landfills generate methane gas through the anaerobic decomposition of organic material in garbage. The gas produced by landfills is a mixture of methane and carbon dioxide. Because methane is a strong greenhouse gas, landfill gas is often burned in a flare as it is vented from the landfill to

prevent it from entering the atmosphere. Imagine three alternative uses for the gas produced by landfills.

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
