What volume of H2so4 Solution Cspecific gravity=-1.28 and strength =24.7% by mass) will be required to react completely with 125g ZnC032?

What does the mass of 0.7891 mol of ferric oxide (fe2o3)

Draw the structure for 5-isopropyl-2-methyl-3-nonene

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.
