Answer:
Saturated Solution
Explanation:
Answer:
Saturated Solution: A solution with solute that dissolves until it is unable to dissolve anymore, leaving the undissolved substances at the bottom.
Chemical changes: occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.
An endothermic: process is any process with an increase in the enthalpy H of the system. In such a process, a closed system usually absorbs thermal energy from its surroundings, which is heat transfer into the system.
An exothermic reaction: is a "reaction for which the overall standard enthalpy change ΔH⚬ is negative." Exothermic reactions usually release heat and entail the replacement of weak bonds with stronger ones.
Rusting: is an iron oxide, a usually reddish-brown oxide formed by the reaction of iron and oxygen in the catalytic presence of water or air moisture. Rust consists of hydrous iron(III) oxides and iron(III) oxide-hydroxide, and is typically associated with the corrosion of refined iron.
Galvanisation or galvanization: (or galvanizing as it is most commonly called) is the process of applying a protective zinc coating to iron or steel, to prevent rusting. The most common method is hot dip galvanizing, in which steel sections are submerged in a bath of molten zinc.
Displacement reaction: also known as single replacement reaction or exchange reaction, is a chemical reaction in which one element is replaced by another in a compound.
Crystal: is defined as a mineral that is generally made of transparent quartz in a shape of cubic symmetry or a glass that is clear, colorless and of high quality. ... A mineral, especially a transparent form of quartz, having a crystalline structure, often characterized by external planar faces.
Crystallisation: is the process by which a solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some of the ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.
Saturated solution: is a solution in which there is so much solute that if there was any more, it would not dissolve. ... When water, or any solvent, has dissolved as much of any substance as it can, it is a saturated solution.
