What made of oxygen gas contains the same number of moles as 56g of sulphur?
(Relative atomic mass:S=32,O=16)
A) 0.56g
B)5.6g
C)56g
D)560g

Matches the chemical name of each oxide of phosphorus to its chemical formula

If you add 5.00 ml of 0.100 m sodium hydroxide to 50.0 ml of acetate buffer that is 0.100 m in both acetic acid and sodium acetate, what is the ph of the resulting solution? acetic acid: ka = 1.8. x 10-5

Which buffer would be better able to hold a steady ph on the addition of strong acid, buffer 1 or buffer 2? explain. buffer 1: a solution containing 0.10 m nh4cl and 1 m nh3. buffer 2: a solution containing 1 m nh4cl and 0.10 m nh3
