False. It is used to show the Ph of something.
Answer:
ouch......it's kinda a practical question..
The statement that describes the oxidizing agent in a chemical reaction is the substance that is reduced because it gains electrons (option D).
<h3>What is a redox reaction?</h3>
A redox reaction is a chemical reaction in which some of the atoms have their oxidation number changed.
In a redox reaction, there are oxidizing and reducing agents. The oxidizing agent is the substance that receives electrons from another substance, hence, becoming reduced.
Therefore, the statement that describes the oxidizing agent in a chemical reaction is the substance that is reduced because it gains electrons.

Its wavelength : 2.31 x 10⁻⁹ m
<h3>Further explanation
</h3>
Radiation energy is absorbed by photons
The energy in one photon can be formulated as
Where
h = Planck's constant (6,626.10⁻³⁴ Js)
f = Frequency of electromagnetic waves
f = c / λ
c = speed of light
= 3.10⁸
λ = wavelength
Frequency of electromagnetic waves : 1.33 x 10¹⁷ Hz
the wavelength :
