This is the balanced chemical equation for a reaction between acetic acid (in vinegar) and sodium bicarbonate (in baking soda).How does this balanced chemical equation represent the conservation of matter in the chemical reaction?
A. There are more carbon (C) atoms represented on the left-hand side than on the right-hand side.
B. The coefficients are the same for each compound represented in the reactants and products.
C. The amount of matter on the left-hand side is the same as the amount of matter on the right-hand side.
D. There are more compounds on the right-hand side than there are on the left-hand side.

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.
