A volcano is a mountain from which molten material is emitted.
The actual outflow of the lava takes place from one or more openings, known as the vents.
The order of decreasing energy is ultraviolet rays, infrared rays, and microwaves.
Frequency is defined as the number of occurrences of the event. In wave function, frequency is the number of times the given waveform passes through a given point. The SI unit of frequency is Hertz.
Photons are particles that do not contain mass but possess energy. Photon energy is calculated by the formula Planck's constant h ( 6.63✖10-34 J/s) multiplied by the frequency. Hence frequency is directly proportional to the energy of the photon.
Higher frequency waves will have higher energy. Lower frequency waves will have lower energy.

Rank the following photons in terms of decreasing energy:
(a) IR (v = 6.5 x 10¹³ s⁻¹)
(b) microwave (v = 9.8 x 10¹¹ s⁻¹)
(c) UV (v = 8.0 x 10¹⁵ s⁻¹)
Explanation:
The given chemical reaction is:
The relation between Eo cell and Keq is shown below:
The value of Eo cell is:
Br- undergoes oxidation and I2 undergoes reduction.
Reduction takes place at cathode.
Oxidation takes place at anode.
Hence,
F=96485 C/mol
n=2 mol
R=8.314 J.K-1.mol-1
T=298K
Substitute all these values in the above formula:
Answer:
Keq=6.13x10^33

Answer:
D.)
Explanation:
The general equilibrium expression looks like this:
In this expression,
-----> K = equilibrium constant
-----> uppercase letters = formulas
-----> lowercase letters = balanced equation coefficients
In this case, all of the reactants and products are gases, so they should all be included in the expression. The products are in the numerator and the reactants are in the denominator. This makes the correct expression:
<----- Insert formulas
<----- Insert coefficients
