A2.00 g sample of a bromine oxide (brxoy) is converted to 2.94 g of agbr. all the bromine in the original oxide compound ends up in the agbr (molar mass for agbr = 187.8). determine the empirical formula of the bromine oxide.

Give the orbital configuration of the phosphorus (p) atom.

Asolid that forms and separates from a liquid mixture is called

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.
