You are making a VERY large cookie. To help the cookie rise, you add baking soda. The baking soda will decompose to
produce carbon dioxide according to the following reaction:
2NaHCO3
Na2CO3 +H2O + CO2
You use 4.80 grams of baking soda (NaHCO3) in the recipe.
What volume of carbon dioxide (in Liters) will this amount of
baking soda produce? The temperature of the oven is 191°C
and you are at standard Wressure.

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.
