Nitrogen makes about 78% of the air we breathe. Nitrogen is extremely important in living things. <span>It forms the building blocks of proteins. We need proteins because they make up our skin and hair. Proteins also help us digest food. We get our nitrogen from plants, and plants get it from bacteria in the soil. Our atmosphere provides life with the nitrogen it needs.</span>
Oxidation is loss of electrons from a substance, and Reduction is gain of electrons by a substance.
These two processes cannot occur without the other. If there is a reduction there must be an oxidation reaction and vice versa. The reactions usually occur simultaneously.
For example, table salt is formed by a redox reaction. Sodium is oxidized i.e. loses an electron (and becomes positively charged) while chlorine gas is reduced i.e. gains the electron (and become negatively charged). The result is formation of sodium chloride.
<span>Yes. a chemical change is when chemical bonds are made or broken. combustion of gasoline (probably octane) makes water and carbon dioxide.</span>
Answer:
Each nitrogen molecule consists of two atoms of nitrogen that are bonded by a triple covalent bond. This is a direct consequence of the fact that each nitrogen atom has 5 valence electrons. Each atom can thus complete its octet by sharing three electrons.

Psychochemical </h3>
Chemical substances that have brief, reversible effects on the body or mind are known as psychochemical agents, often known as incapacitating substances. Psychochemical agents have a longer-lasting effect than riot-control chemicals, which only have a few-minute duration. Central nervous system (CNS) stimulants and depressants both fall within the category of psychochemical substances.
Drugs that depress the central nervous system (CNS) prevent the CNS from functioning and prevent information from traveling across neuron synapses. 3-Quinuchdedinyl Benzilate is an illustration of this group of chemicals, and it has an impact on memory, problem-solving, focus, and instruction-listening abilities. Instead of affecting one's ability to think, cannabinoids and phenothiazines cause sleepiness and a lack of motivation. Although 10,000 times more strong than morphine, fenyls are opiates that have a similar effect.
