The correct answer is: Option (D) 6 aluminum and 9 oxygen!
Explanation:
Since the one molecule of aluminium and oxygen is Al2O3 (Aluminum oxide). It has 3 oxygen atoms and 2 aluminium atoms. It find the atoms for the 3 molecules, multiply them with 3.
3 * 3 oxygen atoms = 9 oxygen
3 * 2 aluminum atoms = 6 aluminum ( Option D)
The answer to this question is the letter A.
As per the question the wavelength of color of light is given as 560 nm.
We are asked to determine the color corresponding to this wavelength.
The visible spectrum corresponds to the wavelength range of 380 nm to 750 nm.
The visible spectrum contains seven colors of light.
The green light corresponds to the wavelength range of 495 nm to 570 nm.
Hence the correct answer to this question will be green light.
