"Solvation, also called dissolution, is the process of surrounding solute with solvent. It involves evening out a concentration gradient and evenly distributing the solute within the solvent." Fuente: ...
"Solubility equilibrium is the equilibrium associated with dissolving solids in water to form aqueous solutions. At the point where no more solid can dissolve, the solution is saturated. The solubilit ...
"In a single replacement reaction, a single element replaces an atom in a compound producing a new compound and a pure element. Like double replacement reactions, metals always replace metals and nonm ...

"There are two main exceptions to electron configuration: chromium and copper. In these cases, a completely full or half full d sub-level is more stable than a partially filled d sub-level, so an elec ...

"Conjugate acid and base equilibrium systems are a type of chemical equilibrium in which the rate of the forward and reverse acid-base reaction are equal. In acid/base reactions, the position of equil ...

"Equilibrium changes are caused by Le Chatlier’s Principle and depend upon the stress applied. Le Chatelier’s Principle predicts the direction of change. For changes in volume, it is important to not ...
"Enzymes are proteins that catalyze chemical reactions by facilitating the positioning of molecules. In biochemical pathways, sequences of enzymes form a chain of chemical reactions. Enzymes, like all ...

"When working with scientific data, we only want to show as many figures as carry accurate meaning, called significant figures. When adding or subtracting two numbers, we round to the same number of d ...
"Entropy measures the amount of disorder in a system. Nature tends towards disorder, so as time elapses, entropy naturally increases. Energy is required in order to decrease entropy." Fuente: BrightSt ...
"Enthalpy is the heat content of a system at constant pressure, but chemists almost always talk about change in enthalpy rather than total energy. Endothermic reactions have positive changes in enthal ...
