Asap!
study the description.
material a allows electrons to move through it freely, while materials b and c do not allow electrons to move through them.
which choice most accurately describes the three materials?
materials b and c must be superconductors while material a is a conductor. electrons can move easily through conductors but not through superconductors.
materials b and c must be conductors while material a is an insulator. electrons can move easily through insulators but not through conductors.
materials b and c must be conductors while material a is an inductor. electrons can move easily through inductors but not through conductors.
material a must be a conductor, while materials b and c are insulators. electrons can move easily through conductors but not through insulators.

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.
