Answer:
Tetrahedral
And can u give me the brainlist I only need one to get a higher rank and thank u
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 />

hope it will help you. Wishing a nice day. enjoy with your answer
Explanation:

Moles of compound =

We have ;
Volume of solution = 600 mL = 0.600 L ( 1 mL = 0.001 L)
Moles of NaOH = n
Molarity of the solution = 3 M

n = 3 M × 0.600 L = 1.800 mol
Mass of 1.800 mole sof NaOH :
1.800 mol × 40 g/mol = 72.0 g
Preparation:
Weight 72.0 grams of sodium hydroxide and add it to the 500 mL of volumetric flask along with some water. Dissolve the all the solute by adding small proportion of water. After the solution becomes clear make the water upto the mark of 500 ml.
Transfer the solution to a bigger beaker and 100 mL of water more to it.
