Answer:
17. NADH has a molar extinction coefficient of 6200 M2 cm at 340 nm. Calculate the molar concentration of NADH required to obtain an absorbance of 0.1 at 340 nm in a 1-cm path length cuvette. 18. A sample with a path length of 1 cm absorbs 99.0% of the incident light at a wavelength of 274 nm, measured with respect to an appropriate solvent blank. Tyrosine is known to be the only chromophore present in the sample that has significant absorption at 274 nm. Calculate the molar concentration of tyrosine in the sample.

Answer:
the rates of rock formation are similar. i could be wrong tho.....
Explanation:
Answer:
Option A) n
Explanation:
In accordance to Quantum Mechanical model of an atom:
- The Principle Quantum number (n) gives the description of the shell of an electron and the energy level of an electron in an atom.
- The angular momentum also referred to as Azimuthal Quantum number (l) gives the description of the shape of the orbitals and helps in determination of angular momentum magnitude.
- The magnetic quantum number (
) describes the energy levels or the number of orbitals contained in a subshell and the way these are oriented within.
- The spin quantum no. (
) determines the elelctron spin's direction which may be (
) or (
).
Like a then it would be A something I guess it goes like that
Nfiltration is the movement of surface water into rock or soil through cracks and pore spaces.
