An isotope of nitrogen experiences the weak force which transforms one of its protons to a neutron. How would this change for an atom? A. It would have no effect because nitrogen still has the same mass number B. It would transform the nitrogen atom to a carbon atom. C. It would make the atom transform it to a heavier isotope of nitrogen. D. It would transform nitrogen to an oxygen atom.

Answer asap need to be answered 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.
