Which one is the largest and which one is the smallest

1 answer:

3 0

I think the easiest way to approach this at first if you don't really work with scientific notation a lot is to convert first

so the options would look like this

A 5/.01

B 6.0/1000

C 2.4/1000000

D .31

largest to smallest A, D, B, C

Calculate the average net charge on phenylalanine if it is in a solution that has a ph of 8.70.

Alex Ar [27]

Phenylalanine has two known pKa charges: 1.83 and 9.13. To determine their individual ionic dissociation charges at pH 10, the equation to be used is

pH = pKa + log [α/(1-α)]

At pKa 1.83:
10 = 1.83 + log [α₁/(1-α₁)]
α₁ = 0.99999

At pKa 9.13:
10 = 9.13 + log [α₂/(1-α₂)]
α₂ = 0.88114

Average Net Charge = 0.99999 + 0.88114 = 1.88

A tarantula was walking along the sidewalk and walked 30 centimeters in 5 seconds. What was the average speed of the spider?

Marina CMI [18]

I’m pretty sure you would have to divide 5 and 30 and you will get 0.16666666 but I would think it would be 6cm/s but I could be wrong and if it is I’m am truly sorry.
