What does Topotactic mean?
a transformation
Filters. (chemistry) Describing a transformation, within a crystal lattice, involving the displacement or exchange of atoms.
What type of reaction is solid to liquid?
The conversion of a solid to a liquid is called fusion (or melting). The energy required to melt 1 mol of a substance is its enthalpy of fusion (ΔHfus). The energy change required to vaporize 1 mol of a substance is the enthalpy of vaporization (ΔHvap)..
What are the applications of liquid liquid extraction?
2 Applications. Liquid-liquid extraction is an important separation method in research and chemical analysis. As a commercial process, it is frequently used in the chemical and mining industries and in the downstream recovery of fermentation products (antibiotics, amino acids, steroids).
What is it called when solid becomes gas?
Under certain conditions, some solids turn straight into a gas when heated. This process is called sublimation. A good example is solid carbon dioxide, also called ‘dry ice’. At atmospheric pressure, it turns straight into gaseous carbon dioxide.
Can all solids change to liquids?
No in the sense that a material must maintain an identical chemical makeup and then change from one phase to another, not all solids have a melting point. Changing from a solid to a liquid state such as when a metal, wax or ice is heated to its melting point, or the specific temperature at which melting occurs.
What is the purpose of solvent extraction?
Solvent extraction, also called liquid – liquid extraction, can be used to separate a substance from a solution by extraction into another solvent. It can be used either to recover a valuable substance from the original solution, or to purify the original solvent by removing an unwanted component.
What is raffinate and extract?
Liquid extraction is the separation of the constituents of a liquid by contact with another insoluble liquid called solvent. The constituents get distributed between the two phases. The solvent rich phase is called extract and the residual liquid from which the solute has been removed is called raffinate.
What is extraction used for in real life?
There are several reasons to use extraction in the chemistry lab. It is a principal method for isolating compounds from plant materials. Extraction moves compounds from one liquid to another, so that they can be more easily manipulated or concentrated. It also enables the selective removal of components in a mixture.
How does a liquid become a gas?
The process of a liquid becoming a gas is called boiling (or vapourization), while the process of a gas becoming a liquid is called condensation. This means that the temperature at which a liquid becomes a gas, the boiling point, can change with surrounding pressure.
Which is the best description of a topotactic transformation?
topotactic (comparative more topotactic, superlative most topotactic) (chemistry) Describing a transformation, within a crystal lattice, involving the displacement or exchange of atoms.
What does the term philosophy literally mean?
Quite literally, the term “philosophy” means, “love of wisdom.”. In a broad sense, philosophy is an activity people undertake when they seek to understand fundamental truths about themselves, the world in which they live, and their relationships to the world and to each other.
What are some of the different areas of Philosophy?
This is why philosophy also encompasses such areas as: Philosophy of Law Philosophy of Feminism Philosophy of Religion Philosophy of Science Philosophy of Mind Philosophy of Literature Political Philosophy Philosophy of the Arts Philosophy of History Philosophy of Language
What’s the best definition of Philosophy for kids?
Kids Definition of philosophy 1 : the study of the basic ideas about knowledge, right and wrong, reasoning, and the value of things 2 : a specific set of ideas of a person or a group Greek philosophy 3 : a set of ideas about how to do something or how to live Live and let live—that’s my philosophy.
