When a molecule with acidic protons enters into an environment with a pH value that is greater than the pKa of its functional groups, the molecule will lose the proton(s) in question. Consider the structure of the amino acid histidine in its fully protonated form. How would the amino acid appear in a slightly basic environment of pH 8, given the following structure and the pKa values of the acidic protons? Bear in mind, that when the pH of the solution is greater than the pKa of the proton, that proton will be lost.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying

since electrons are negative the answer is neagtaive
