Tris {(hoch2)3cnh2} is one of the most common buffers used in biochemistry. a solution is prepared by adding enough tris and 12

shusha [124]

Given that,

The concentration of TRIS = 0.30 M

The concentration of TRIS+ = 0.60 M

Kb = 1.2 x 10^-6

pKb = -log Kb = - log (1.2 x 10^-6) = 5.920

Now, by using the Hendersonn equation,

pH = pKa + log TRIS+/TRIS = 5.920 + log (0.60/0.30) = 6.221

pOH=14-pH=14-6.221 = 7.779

The density of copper is 8.92 grams per milliliter. What volume of water will 40.0 grams of copper displace?

Klio2033 [76]

Density:

The density of a substance is equal to the ratio of its mass and volume. In general we can say the density of a substance is mass per unit volume.

Density = mass in g / volume in cubic cm or ml

Given that

Density = 8.92 g/ ml

Mass = 40.0 g

Therefore,

Volume = mass/ density

= 40.0 g/ 8.92 g/ ml

= 4.48 ml

Thus the correct answer is 4.48 ml

Draw every stereoisomer for 1,2-difluoro-1,2-dimethylcyclopentane. Use wedge-and-dash bonds for the substituent groups, and be s

Blizzard [7]

Answer:

See figure 1

Explanation:

In this question, we have to find first the chiral carbons on 1,2-difluoro-1,2-dimethylcyclopentane. Carbons 1 and 2. Then, using the Cahn–Ingold–Prelog priority rules. We can draw all the stereoisomers. If we have 2 chiral carbons we will have ( $2^n=2^2=4$ ) 4 isomers. With this in mind we can have the R,R isomer; the S,S isomer; the S,R isomer, and the R,S isomer. We have to remember that:

Priority 1 = "F"

Priority 2= "C"

Priority 3= "CH2"

Priority 4 = "CH3"

I hope it helps!

igomit [66]

Answer:

The drawings are in the figure attached below.

Explanation:

"Constitutional isomers" is a term used in chemistry to refer to chemical compounds that have the same constitution and molecular formula distributed in a different structure. That is, the compound has the same atoms, but when built in a three-dimensional image, these atoms occupy different places within the same structure.
