Weak Acids: Theoretical Explanation
Ethanoic acid (acetic add) is a weak acid which dissociates in water. CH3 COOH + H2 0 ≈ CH3 C00– + H3O+ An add…
Molecular Structure: Theoretical Explanation
The water molecule has an O—H bond distances of 0.9687 x 10-10 m and the distance between the two hydrogen atoms is 1.5391 x 10-10 m. Calculate…
Explain Conjugated Molecule and Quantum Chemistry
A conjugated molecule (also called a polyene) is one with alternating single and double carbon-carbon bonds in its backbone. Linier conjugated molecule, H= gray, C=…
Polymer Chemistry: Mathematical Explanation
Long polymer molecules tend to coil up rather than being stretched out straight, below Figure is an example of a short polythene molecule. Randomly coined…
Explain Crystal Structures by X-Ray Diffraction?
When a molecule forms a crystalline solid we can use X-ray diffraction to determine the positions of the atoms within the molecule. X-rays are very…
Chemical Equilibrium and Concentration Calculations
H2 + I2 ≈ 2 HI The above chemical reaction when carried out at a temperature of 425°C has the I2, HI and H2 all…
What is Hydrogen-Atom Spectroscopy?
The Rydberg equation very accurately summarizes the UV-visible electronic spectroscopy that is observed for the hydrogen atom. It gives the wavenumber f, (pronounced “nu bar”)…
Enthalpy of Combustion of Benzene
When benzene, below Figure, is combusted it has the following stoichiometric reaction C6 H6 + 15/2 O2 → 6CO2 + 3 H2O The enthalpy change…
