Suppose you were to weigh out exactly 5 times the mass of sodium acetate used in buffer A (.200g) and dissolve this in .25 M acetic acid to make another buffer. How would the theoretical pH of this buffer differ from your other buffers?

What are the spectator ions in 2h+ + so42- + ca2+ + 2r → caso4 + 2h+ + 21?

Find the mass in grams of 1.37x1020 particles of h3po4

If we compare and contrast electromagnetic waves with sound waves, all but one statement is true. that is a) sound waves require a medium to travel while electromagnetic waves do not. b) electromagnetic waves can travel through the vacuum of space while sound waves cannot. c) electromagnetic waves must have a medium in which to travel, but sound waves can travel anywhere. eliminate d) sound waves must bounce off of matter in order to travel while electromagnetic waves do not require matter to be present.
