Discharging or charging often happens at any given time within a battery. This induces electrical energy to discharge or generate the battery.... View Article
Hess's law states that in a chemical reaction, the rise in enthalpy, i.e. reaction heat at constant pressure, is independent of the phase between... View Article
The change in enthalpy ('H') that happens during catalytic hydrogenation. Used as a probe of alkene stability, alkyne stability, conjugation, and... View Article
In a reversible reaction, the reaction usually happens in both forward and reverse directions at the same time. Although reactants react to the... View Article
There are 2 missing electrons in the oxygen valence shell. It can therefore only form a maximum of 2 bonds, if both are sigma bonds.Oxygen is... View Article
The electronegativity of the suspension groups decreases, the polarity of the bonds decreases, and the angles of the bonds increase from left to... View Article
Alkanes are much less reactive than alkenes and, in the presence of UV light, can only react with bromine water. Under these conditions, alkanes... View Article
The lengthier the alkyl chain, the less alcohol is soluble in water. In water, methanol and ethanol are infinitely miscible; there is minimal... View Article
Formic acid is stronger than benzoic acid because it has a lower pKa value. Formic acid does not have such a group of electron donors and is... View Article
For neutralisation reactions, sulfuric acid is used almost universally. It is simpler and better to use than HCl or HNO3 and, except for... View Article
Aniline is given by an ammonia reaction with ammonia in the presence of a phenol dehydrating agent. At room temperature, Phenol reacts with... View Article
Phenol is neutralised by sodium hydroxide, which forms sodium phenate or phenolate, but can not be neutralised by sodium bicarbonate or sodium... View Article
When an electron withdrawing nitro group is present in para position to the −OH group, due to phenoxide ion stabilisation, the acidity is... View Article
In apples approximately 80 to 90 % of organic acids are malic acid. Sheele, who isolated this acid from unripe apples in 1785, first described... View Article
The current applied to the electroplating cell is increased, as well as the amount of metal that is coated. Compared to the one with a diluted... View Article
Alkanes and cyclo-alkanes are possibly the least chemically reactive class of organic compounds, with the exception of cyclopropane. Alkanes... View Article
The areas are usually separated by a membrane. High concentration to low concentration is the concentration gradient. Going against the gradient... View Article
No, ac current cannot be used in electrolysis. In chemistry and manufacturing, electrolysis is a technique that uses direct electric current (DC)... View Article
Thermodynamic equilibrium refers to the concept of temperature on a broad scale. They are said to have the same temperature when two objects are... View Article
The amine functional group is made up of a N atom bound through σ bonds to either C or H atoms. Due to the N atom's electronegativity, both the... View Article
