We cannot answer the question if we do not have the answers - sorry!!
Answer:

Explanation:
One mole of a substance contains the same amount of representative particles. These particles can be atoms, molecules, ions, or formula units. In this case, the particles are atoms of titanium.
Regardless of the particles, there will always be <u>6.02*10²³</u> (also known as Avogadro's Number) particles in one mole of a substance.
Therefore, the best answer for 1 mole of titanium is D. 6.02*10²³ atoms.
The heat remains constant because there’s nothing to cool it down
Answer:
240 m
120 m
Explanation:
d = Path difference = 120 m
For destructive interference
Path difference

The longest wavelength is 240 m
For constructive interference

The longest wavelength is 120 m
