Answer:
Orange, blue
Explanation:
A way to determine the color of a compound is using the Crystal Field Theory (CFT), which depends on the wavelengths of the electromagnetic spectrum.
The spectrum is formed by different wavelengths, each one with a color. The color happens when the electron is excited, and the goes from a higher level. When it returns to its original energetic level, it releases a photon, in a color way.
So, in CFT, the substance is placed in a light with a mixture of colors. The photon will absorb the color of its wavelength and will reflect the other color, which will be seen in the solution. In this case, the mixed light was prepared with blue and orange colors.
Then, the Cu(H₂O)₆²⁺ ions will absorb the orange color, and reflect the blue one, and the solution will be blue. The beta-carotene will absorb the blue color and will reflect the orange, so the solution will be orange.
The logarithm from my understanding can never be negative. You can check this on a calculator. You may have a negative if it is shown as -(log x).
<span>The orbital diagram for
phosphorus consists of five electrons in the third shell, eight in the
second and two in the first shell, closest to the nucleus. The atomic number of phosphorus is 15. This number indicates the total number of electrons.
Ta Da!!!
Just do a little research!!!
Or not you know, that's what we're here for... </span>

Answer: What are phase fractionation methods used for? well They apply to the prefractionation of the sample to obtain less complex protein mixtures for an easier analysis; they are also used as a means to evidence specific proteins or protein classes otherwise impossible to detect.
Explanation: in spanish /
Se aplican al prefraccionamiento de la muestra para obtener mezclas de proteínas menos complejas para un análisis más fácil; también se utilizan como un medio para evidenciar proteínas específicas o clases de proteínas que de otro modo serían imposibles de detectar.
