Histidine is a polyprotic acid. , using excel to:
a. calculate fractions (αi ) of all the species as a function of ph in the range of 1-13. use the equations given below. calculate αi at every 0.2 ph unit to obtain a smooth plot. plot the fractional concentration vs. ph for all the species.
b. identify and mark species at all intersection points and peaks.

answer: you could do some invislibe ink.

explanation: i will tell you how to if u answer my question.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
