Answer:
Two (2) types of ions
Explanation:
Metal ions (cations) and negatively charged ions (anions) of either chloride, carbonate, sulphides or hydroxides are present during the selective precipitation.
Majorly, the process determines the metal ions present by initiating precipitation as certain conditions.
I hope this was helpful.
Answer:
6 m/s is the answer.
Explanation:
speed = distance/time
(please mark me brainliest if you can)
The absorbed and perceived color of the solution at wavelength 533 nm will be GREEN AND YELLOW.
The spectrophotometer is an analyzing machine that uses the interaction between the radiation from the visible of part of the electromagnetic spectrum and the behavior of chemical species to identify compounds.
When all the wavelength in the visible light is present, we see the color of the light as white but when a wavelength is removed or absorbed, the white color will change to another color. This is the principle on which the spectrophotometer work. Thus, when the wavelength of 533 nm is removed, the color that will be perceive is green and yellow.<span />
Molar mass is the mass of each element multiplied by subscript, then added together.
So, we’ll do
C = 12g x 12 = 144 g
H = 1g x 22 = 22 g
O = 16g x 11 = 176 g
The total of all of these is the molar mass: 342 g in a mol
The amount of mols of each element in each compound is likely equal to its subscripts.
C = 12 mols
H = 22 mols
O = 11 mols
For the atoms, you’ll multiply each one of the above by Avogadro’s number
Avogadro’s Number: 6.02 x 10^23 atoms/mol
