Quiz
a large molecule composed of repeating structural units, or monomers, covalently bonded together in a chain-like structure

polimero, polimero grande
each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, leading to variation in atomic mass

isotopo, isotopi
containing or relating to a dangerous form of energy produced by nuclear reactions

radioattivo
a chemical bond where atoms share electrons to form a stable molecule

legame covalente, banda covalente
a type of chemical bond between two atoms involving the sharing of two pairs of electrons, resulting in a stronger and more stable connection than a single bond

doppio legame, legame doppio
defining substances or surfaces that have a strong attraction to water molecules, allowing them to easily absorb or interact with water

idrofili, affini all'acqua
characterized by substances or surfaces that repel water molecules, showing little or no affinity for water

idrorepellente, idrofobo
a chemical reaction that releases heat energy to its surroundings, typically resulting in a temperature increase

reazione esotermica, reazione che libera calore
a chemical process that absorbs heat energy from its surroundings, often resulting in a temperature decrease

reazione endothermica, processo endothermico
the weighted average mass of an atom of an element, taking into account the masses of all its naturally occurring isotopes

massa atomica, massa atomica media
the total number of protons and neutrons in the nucleus of an atom

numero di massa, massa atomica

mole, molecula
a laboratory tool used to measure and transfer small volumes of liquid

pipetta, pipettone
a device that spins samples to separate components based on density

centrifuga, centrifugo
a tabular arrangement of chemical elements organized based on their atomic number, electron configuration, and recurring chemical properties

tabella periodica, tavola periodica
the process where calcium or calcium salts accumulate in a tissue, making it hard and rigid

calcificazione, sprissatura
a laboratory method used to determine the concentration of a substance in a solution by gradually adding a reagent of known concentration until a reaction is completed

titolazione, titratura
the process by which microorganisms convert carbohydrates into alcohol, acids, or gases

fermentazione, fermento
the measure of how much of a substance is present in a certain volume of solution

concentrazione, diluzione
a group of atoms bonded together that behaves as a single unit within a molecule

radicale, gruppo radicalico
a test that measures the presence, amount, or activity of a specific substance in a sample, often used in scientific and medical research

saggio, analisi
a state in a chemical reaction where the forward and reverse reactions occur at the same rate, resulting in no net change in the concentrations of reactants and products

equilibrio dinamico, stato di equilibrio
(chemistry) the process of separating a liquid or solution into its parts by passing electricity through it

elettrolisi, processo di elettrolisi
to make a solution or mixture weaker or less concentrated by adding more liquid

diluire, diluirlo
to disperse fine particles throughout a fluid so they remain evenly distributed without settling

sospendere, disperdere
a tiny, tube-shaped structure made of carbon atoms, with remarkable strength and electrical properties

nanotubo, tubulo nano
a phase is a distinct form of matter with uniform chemical and physical properties, separated from other forms by boundaries

fase, stato
to eliminate or neutralize harmful substances

disintossicare, detossificare
denoting substances with a highly organized molecular structure, akin to crystals

cristallino, cristallizzato
a scientist who studies the structure and properties of crystals

cristallografo, cristallografa
a laboratory technique used to separate and analyze mixtures of substances based on their differential affinities for a stationary phase and a mobile phase

cromatografia, metodo cromatografico
a type of radioactive decay where a nucleus emits a beta particle (electron or positron) to transform a neutron into a proton or vice versa

decadenza beta, beta decadenza
a device that turns vapor into liquid by cooling it

condensatore, condenser
weak attractive forces between molecules or atoms, arising from temporary or induced dipoles

forze di van der Waals, interazioni di van der Waals
a scientist or engineer who specializes in the study and production of metals and alloys, including their properties, processing methods, and applications

metallurgista, esperto di metallurgia
the process by which molecules of a substance adhere to the surface of a solid or liquid, forming a thin film or layer

adsorbimento, adsorbimento superficiale
a renewable, alternative fuel made from organic materials such as vegetable oils, animal fats, or recycled cooking grease

biodiesel, biocarburante
