Pink Egg #2 1.14 sink Purple Egg #3 0.76 float Yellow Block #4 17.28 sink T Gray Cube #8 0.94 float Purple Cone #9 2.26 sink CONCLUSION The density of water is 1.0 g/mL. Look at the data in your table. How can you use the density of an object to predict whether it will sink or float? help what to say

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.
