Q. Illustrate Nature of light as a particle?
Ans. You have seen that when excited electrons return to the ground state they release packets of energy, called photons. Photons are also known as light particles. Light is a strange creature. While we often refer to its wave properties, we also can mention its properties as a particle.
The energy of a photon relates to the color of light we see. High energy photons might emit in the ultraviolet region of the spectrum while low energy photons would wind up in the infrared. The relationship between the energy of a photon and the color we see is summed up in the following equation:
ΔE = hν
where E is the energy, h is Plank's constant (6.626 x 10-34 Joule seconds), and is the frequency of the radiation.
The fresh feed to an ammonia production process contains nitrogen (N 2 ) and hydrogen (H 2 ) in stoichiometric proportion, along with an inert gas (I). The feed is combined with
The combustion of propane occurs via the reaction: C3H8(g)+5O2(g)-->3C02(g)+4H2O(g) Hoe many grams of oxygen are required to burn completely 10.0g of propane?
The difference among Threshold energy and average energy of the molecules is known as activation energy.

What is Standard deviation? Standard deviation tells about the widely spread out of the measured analytical data points. Highly precised measurements are less standard deviation.
