Kvíz
a large molecule composed of repeating structural units, or monomers, covalently bonded together in a chain-like structure
polymer, polymér
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
izotop, izotopy
containing or relating to a dangerous form of energy produced by nuclear reactions
radioaktivní, radioaktivní (izotopy)
a chemical bond where atoms share electrons to form a stable molecule
kovalentní vazba, covalentní spojení
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
dvojná vazba, dvě vazby
defining substances or surfaces that have a strong attraction to water molecules, allowing them to easily absorb or interact with water
hydrofilní, vodomilný
characterized by substances or surfaces that repel water molecules, showing little or no affinity for water
hydrofobní, odpuzující vodu
a chemical reaction that releases heat energy to its surroundings, typically resulting in a temperature increase
exothermní reakce, reakce uvolňující teplo
a chemical process that absorbs heat energy from its surroundings, often resulting in a temperature decrease
endotermická reakce, endotermní reakce
the weighted average mass of an atom of an element, taking into account the masses of all its naturally occurring isotopes
atomová hmotnost, atomová hmotnostní průměr
the total number of protons and neutrons in the nucleus of an atom

periodická tabulka, tabulka prvků
the process where calcium or calcium salts accumulate in a tissue, making it hard and rigid
kalcifikace, kalcifikování
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
titrace, titrace látky
the process by which microorganisms convert carbohydrates into alcohol, acids, or gases
fermentace, kvašení
the measure of how much of a substance is present in a certain volume of solution

a group of atoms bonded together that behaves as a single unit within a molecule
radikál, skupina atomů
a test that measures the presence, amount, or activity of a specific substance in a sample, often used in scientific and medical research
analýza, zkouška
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
rovnováha, vyváženost
(chemistry) the process of separating a liquid or solution into its parts by passing electricity through it
elektrolýza, elektrolytický rozklad
to make a solution or mixture weaker or less concentrated by adding more liquid
ředit, zředit
to disperse fine particles throughout a fluid so they remain evenly distributed without settling
rozptýlit, dispergovat
a tiny, tube-shaped structure made of carbon atoms, with remarkable strength and electrical properties

a laboratory technique used to separate and analyze mixtures of substances based on their differential affinities for a stationary phase and a mobile phase
chromatografie, chromatografická analýza
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
beta rozpad, beta decay
not having an electrical charge

the process by which molecules of a substance adhere to the surface of a solid or liquid, forming a thin film or layer
adsorpce, adsorpční proces
a renewable, alternative fuel made from organic materials such as vegetable oils, animal fats, or recycled cooking grease
biodiesel, biodieslové palivo
a specific composition of a mixture of substances, typically metals or alloys, where the melting point is at its lowest possible temperature under atmospheric pressure
