D= 0.10125kg/m^3
EXPLAINATION
Density =mass/volume
D= 226.8/20 x 8 x 14
D=226.8/2240
D= 0.10125kg/m^3
Hope it was helpfull!!
Answer: Very small fragments of solid materials or liquid droplets suspended in air are called particulates. ... For example, solid particulates between roughly 1 and 100 μm in diameter are called dust particles, whereas airborne solids less than 1 μm in diameter are called fumes.
Brainliest would be nice!
Explanation:
The energy required is Ionization energy
Let us see the structure of given compound melatonin
The two nitrogen atoms appear to be sp3 hybridized but the actual hybridization of both the nitrogens in the structure is sp2 as they have to gain planar geometry so that they can participate in the resonance making the compound more stable
so answer is
sp2 hybridized
trigonal planar geometry
