History of chemistry - Wikipedia
The history of chemistry represents a time span from ancient history to the present. By 1000 BC, civilizations used technologies that would eventually form the basis of the various branches of chemistry. Examples include the discovery of fire, extracting metals from ores, making pottery and glazes, fermenting beer and wine, extracting chemicals from plants for medicine and perfume,
Understanding Atomic Radius Trends: The 2 Key Principles
Feb 07, 2021One exception is the noble gases. The six noble gases, in group 18 of the periodic table, are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The noble gases are an exception because they bond differently than other atoms, and noble gas atoms don't get as close to each other when they bond.

Air - Molecular Weight and Composition . Dry air is a mixture of gases where the average molecular weight (or molar mass) can be calculated by adding the weight of each component. Air - Prandtl Number . Prandtl number for air vs. temperature and pressure. Air - Properties at Gas-Liquid Equilibrium Conditions
Some Basic Concepts of Chemistry Class 11 Notes Chapter 1
Jun 07, 2022Molecular Mass Molecular mass is the sum of atomic masses of the elements present in a molecule. It is obtained by multiplying the atomic mass of each element by number of its atoms and adding them together. For example, Molecular mass of methane (CH4) = 12 u + 4 (1 u) = 16 u Formula Mass
400+ TOP CHEMICAL ENGINEERING Interview Questions and Answers
The gram-equivalent weight of the dissolved substance is the molecular weight of the dissolved substance divided by the hydrogen equivalent of the dissolved substance. Citric acid has a molecular weight of 192 and it contains three hydrogen equivalents (i.e., three COOH groups).
600+ TOP Mechanical Engineering Interview Questions and Answers
For subsonic flow at inlet section of a diffuser a lower velocity and higher pressure will exist at the exit section. For supersonic isentropic flow at the inlet section a higher velocity and lower pressure will exist at the exit but if a shock wave occurs in the diffuser then a higher pressure will exist at the exit. 98.
NEET Chemistry Syllabus 2022 - Detailed Class Wise Syllabus
NEET Chemistry Syllabus is constituted by Physical Chemistry, Inorganic Chemistry, and Organic Chemistry sections from classes 11 and 12. NEET Chemistry section is deemed as the scoring section as chemical reactions, mechanisms, compositions, chain reactions for students typically is the bare minimum, fundamentals to be covered.
Phase Diagrams – Chemistry - University of Hawaiʻi
(f) 50 °C and 0.3 kPa. Solution Using the phase diagram for water, we can determine that the state of water at each temperature and pressure given are as follows: (a) solid; (b) liquid; (c) liquid; (d) gas; (e) solid; (f) gas. Check Your Learning What phase changes can water undergo as the temperature changes if the pressure is held at 0.3 kPa?
