The portion of the electromagnetic spectrum do we need to observe is the red part of the This is further explained below.
<h3>What is
electromagnetic spectrum?</h3>
Generally, Spectrum refers to the range of wavelengths or frequencies that electromagnetic radiation may cover.
In conclusion, We need to keep an eye on the red part of the electromagnetic spectrum since a large positive redshift causes an increase in wavelength and a corresponding fall in frequency and photon energy (such as light).

Answer:
Solute - The solute is the substance that is being dissolved by another substance. In the example above, the salt is the solute. Solvent - The solvent is the substance that dissolves the other substance. In the example above, the water is the solvent.
Explanation:
Since HCl04 is a strong acid, being [H+], and a molarity of 2.1 M.
To solve for pH:
pH = -log (M) = -log(2.1M) = -0.32, which is clearly a negative number.
However, to verify the answer, just use the pH meter in determining the pH of the solution.
Compounds
Explanation:
Compounds are substances that can be broken down by chemical means. They are categorized as pure substances due to their definite composition.
- Compounds are substances composed of two or more kinds of atoms or elements joined together in a definite grouping.
- Properties of compounds differs from those of the constituent atoms.
- Compounds are broken down by chemical means because they are products of chemical changes.
- Several kinds of compounds exists through combinations of atoms.
- Compounds have definite compositions
