One of two or more compounds that have the exact same number and type of atoms but have very different geometric arrangements.
<h3>What is structural isomers?</h3>
In a structural isomer, sometimes referred to as a constitutional isomer, two or more organic molecules have the same molecular formulae but distinct structures. Despite having the identical chemical formula, the two molecules below differ in where the methyl group is located, making them into distinct molecules.
<h3>What is chemical reaction?</h3>
Chemical reactions occur when one or more chemicals, known as reactants, are changed into one or more new compounds, known as products. Chemical components or compounds make up substances. The atoms that make up the reactants are rearranged in a chemical reaction to produce various products.

NH₃:
N = 8*10²²
NA = 6.02*10²³
n = N/NA = 8*10²²/6.02*10²³ ≈ 1.33*10⁻¹=0.133mol
O₂:
N=7*10²²
NA = 6.02*10²³
n = N/NA = 7*10²²/6.02*10²³ = 1.16*10⁻¹=0.116mol

Answer: The forensic examination of substances involve a preliminary flame test.
Explanation:
The forensic chemical analysis of samples involves the flame testing which is one of the preliminary test. The materials are burned on a flame and the color of the flame is considered indicative of the elements present in the material.
The substances like Borax (sodium borate), Copper(II) sulfate, and boric acid burn with a characteristic green flame.
