The chemical described above belongs to CLASS 1 EXPLOSIVES of DOT hazardous material classification. An hazardous substance is any substance which can cause adverse effects in humans when exposed to it. These substances are divided into different categories based on the way they react in different situations. It is mandatory that you aware of the kind of chemical you are working with when you are in the laboratory in order to take appropriate precautionary steps.

Answer:
Genetic equilibrium is the state in which allele frequencies do
not change in a generation over generation.
Explanation:
Genetic equilibrium can be described as a situation which arises when a certain allele or genotype remains constant for a species generation over generations. Genetic equilibrium can be maintained if no external factors like mutations affect the population of the species. The phenomenon of natural selection and evolution need to be stopped if a genetic equilibrium is to be maintained. Hardy-Weinberg theorem is the mathematical depiction of genetic equilibrium.
Answer:
1.22 × 10^22 H atoms
Explanation:
From this question, TNT has the chemical formula: C-H5N306. The number of nitrogen atoms in the TNT substance is said to be 7.30 × 10^21 atoms.
The number of hydrogen atoms in the same TNT substance can be got using mole ratio. Based on the chemical formula, the mole ratio of hydrogen to nitrogen is 5:3 i.e. H5N3.
This means that;
Number of atoms of hydrogen = 5/3 of the number of atoms of nitrogen.
Hence, number of H atoms = 5/3 × 7.30 × 10^21
number of H atoms = (7.30 × 5/3) × 10^21
number of H atoms = (36.5/3) × 10^21
number of H atoms = 12.1666 × 10^21
number of H atoms = 1.2166 × 10^22 atoms.
Approximately, number of H atoms in TNT is 1.22 × 10^22 atoms.
The corrosion process is a result of the undesired reaction of metals with agents in the environment. The corrosion reaction involves the metal:
becoming reduced
becoming oxidized
<u>becoming the oxidizing agent </u>
becoming more metallic
