Air: Is it a Compound, Element, or Mixture?
Air is a mixture of several gases, not a composition. Nitrogen, oxygen, the life-sustaining ingredient for animals and humans, carbon dioxide, water vapor, and trace amounts of other elements make up the atmosphere (argon, neon, etc.). Ozone, helium, and hydrogen are also found in higher…
Turgidity: All you need to know about it
Turgidity is required for plant cells to stand in one place for long periods. Turgid describes a cell that has been fully bolstered. It’s a cellular phase in which a plant cell is in a state of tension after drowning in water. Thus, turgidity is…
Circle Of Illumination: Definition, Motions, Terms & Revolution
We might have wondered how exactly night comes after a day or how the earth decides how many hours will be there in each. This is what the circle of illumination does- the division of the hours of a day into day and night. What…
Areolar Tissue: Definition, Functions, Structure & Location
Cells are the structural and functional units that cover the entire human body. Instead of the cells having an individual structure, they are grouped into clusters. We call these clusters ‘tissues’. Biologically, tissues are groups of cells that have a collective function. The cells might…
Combination Reaction: Definition, Examples & Exothermic In Nature
Substances combine chemically to create new substances. The new substances have properties completely different from the initial substances. The initial substances that undergo the reaction are called reactants. The reaction between the reactants creates the substances called the products. In other words, a chemical reaction…
Superposition Theorem: Definition, Explanations, Conditions & How To Apply
The superposition theorem is based on the superposition principle which is used to analyze networks in electrical circuits. It is essential because it operates in the process of converting any circuit to either its Norton correspondent or its Thevenin equivalent. This theorem is functional for…
Ammonia – a Lewis Acid or a Lewis Base?
One of the fascinating substances to learn about is ammonia or NH3. It has a pleasant odor and emits a colorless, fire-resistant gas. One nitrogen atom and three hydrogen atoms make up this compound. Ammonia is a polar molecule because its electron sharing is asymmetric….
Sodium Nitrite: Chemical Formula, Structure, Characteristics & Synthesis
This article explains the formula for sodium nitrite. It is an inorganic compound that is an extremely unstable alkali metal nitride. To make it, atomic beams of nitrogen and sodium are mixed and deposited at low temperatures on a sapphire substrate. As a result, it…
Are Spiders a Kind Of Insect? How Many Legs Does It Have?
Spiders are there all around us. However, they are not proper insects as we think them to be. They belong to the animal kingdom of Arachnida, while insects belong to Arthropoda. Spiders have 8 legs, and their fangs can inject venomous fluids. These creatures are…
How To Find The Molar Mass Of a Molecule Of Oxygen (O2)?
Oxygen is one of the most abundant elements in the universe and is only next to nitrogen in the atmosphere. Knowing the molar mass of oxygen is very important. So, for this, we need to know what molar mass is and how it is calculated…
