The wavelength of yellow light is 580nm which is 580×10⁻⁹ m, so its frequency will be 5.17×10¹⁴ m/s.
The frequency and the wavelength are indirectly proportional to the each other. More is the wavelength, lesser is frequency and vice-versa. The speed at which a wave travels is equal to product of the frequency and wavelength, which justifies link between these two parameters.
V = λ f
where,
V is wave speed,
f is wave frequency,
λ is wavelength.
Given that,

What are ideal gases?
The term ideal gas refers to a virtual gas composed of molecules that obey some rules.
Ideal gas molecules do not attract or repel each other. The only interactions between ideal gas molecules are elastic collisions when they collide with each other or with the walls of the container.
Ideal gas molecules take up no volume by themselves. Gases occupy volume as their molecules expand into large regions of space, but ideal gas molecules are approximated as point particles that have no volume of their own.
What is the molar form of the ideal gas law?
Ideal gas pressure, P, volume V, and temperature T are related by a simple equation called the ideal gas law. The simplicity of this relationship is an important reason why we usually treat gas as ideal unless there is another reason.

2. Energy is neither produced nor evolved to form mixture.
3. The mixture has no fixed boiling points and melting points.
4. Components of mixtures can be separated by physical methods simply.

i think you’re suppose to talk about the equilibrium switching and favouring things
In addition to H²O equilibrium, the reaction will move forward direction.
Le Chatelier's precept, additionally known as Chatelier's principle, is a precept of chemistry used to predict the impact of exchange in conditions on chemical equilibrium
Le Châtelier's principle states that if a dynamic equilibrium is disturbed by changing the situations, the position of equilibrium shifts to counteract the alternate to reestablish equilibrium. Le Chatelier's precept may be stated as follows: A exchange in one of the variables that describe a machine at equilibrium produces a shift inside the function of the equilibrium that counteracts the effect of this change.

Propan-1-ol, 4-methylphenol, 3-nitrophenol, phenol, 3, 5-dinitrophenol, and 2, 3, and 6-trinitrophenol are listed in increasing order of acid strength.
Which has the most acidity?What acid has the most strength? Fluoroantimonic acid is actually a blend of hydrofluoric acid and pentafluoride antimony, making carborane superacids the strongest solar acids in the world. The pH level of carborane is -18.
Which of the following acids has the greatest Mcq value for acidity?Acid o-nitrobenzoic ,Nitrophenol and m-nitrobenzoic acid are two related compounds. Solution: O-nitrobenzoic acid has the highest acid strength due to the nature of the -'NO (2)' group, which withdraws electrons, and the "ortho effect."

What are 4 examples of radicals?.
Typical Free Radicals Radicals such as superoxide anion, hydrogen peroxide, hypochlorite, nitric oxide, and peroxyntrite
What is the purpose of hypochlorite?Most usually, bleach, also known as sodium hypochlorite, is used as a disinfectant. It works well to kill viruses, germs, fungi, and mycobacterium. It is a broad-spectrum disinfectant.
What effects does hypochlorite have on water?Similar to chlorine, sodium hypochlorite creates hypochlorous acid when it is discharged into water. The pathogens in the water, such as bacteria, viruses, and protozoa, then react with this acid and become inactive, making them unable to multiply or constitute a threat to human health.
