Finally, what mass of Na2HPO4 is required? Again, assume a 1.00 L volume buffer solution. Target pH = 7.37
Acid/Base pair: NaH2PO4/Na2HPO4
pKa = 7.21
[Na2HPO4] > [NaH2PO4]
[NaH2PO4] = 0.100 M
12.0 g NaH2PO4 required
[base]/[acid] = 1.45
[Na2HPO4] = 0.145 M

Schrodinger and heisenberg developed an alternate theory about atomic nature that contradicted some of bohr's model of the atom. how do changes resulting from new technology and evidence affect the reputation of the atomic theory?

Turbo the snail moves across the ground at a pace of 12 feet per day. if the garden is 48 feet away, how many days will it take for the snail to get there?

The scheme below is from a series of reactions that are part of a synthesis of vitamin a. answer the following questions with reference to this scheme. (i) what is "reagent a"? (ii) draw a step-by-step mechanism which explains the formation of compound c from compound b (iii) which reagents would you use to form compound e from compounds c and d (reagents b and c)? for each reagent suggested above in (ii) explain the role of the reagent in the reaction to (iv) form compound e. you may wish to do this by drawing a mechanism. 1. addition of reagent a но reagent a 2. н,о" thо oh нон-с compound a. compound b. compound c .ch-оh 1. reagent b "сно 2. reagent c сh oh compound e. compound d.
