Flashcards
Pagbaybay
Pagsusulit
a large molecule composed of repeating structural units, or monomers, covalently bonded together in a chain-like structure
polimer
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
isotope
containing or relating to a dangerous form of energy produced by nuclear reactions
radioactive
a chemical bond where atoms share electrons to form a stable molecule
covalent bond
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
dobleng bono
defining substances or surfaces that have a strong attraction to water molecules, allowing them to easily absorb or interact with water
hydrophilic
characterized by substances or surfaces that repel water molecules, showing little or no affinity for water
hydrophobic
a chemical reaction that releases heat energy to its surroundings, typically resulting in a temperature increase
exothermic na reaksyon
a chemical process that absorbs heat energy from its surroundings, often resulting in a temperature decrease
endothermic na reaksyon
the weighted average mass of an atom of an element, taking into account the masses of all its naturally occurring isotopes
atomic mass
the total mass of all the atoms in a single molecule of a substance
molekular na masa
the total number of protons and neutrons in the nucleus of an atom
Pangkalahatang numero
a fundamental unit in chemistry that represents the amount of substance containing as many entities (atoms, molecules) as there are in 12 grams of carbon-12
nunal
a container usually made of glass or plastic used in chemistry and laboratory
beaker
a laboratory tool used to measure and transfer small volumes of liquid
pipette
a device that spins samples to separate components based on density
centrifuge
a special paper treated with chemicals that change color in response to certain conditions, used to test for the presence of specific substances or measure pH levels
papel na tagapagpahiwatig
a tabular arrangement of chemical elements organized based on their atomic number, electron configuration, and recurring chemical properties
periodic table
the process where calcium or calcium salts accumulate in a tissue, making it hard and rigid
pagsasakaltsiyum
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
pagsukat sa titi
the process by which microorganisms convert carbohydrates into alcohol, acids, or gases
pagbuburo
the measure of how much of a substance is present in a certain volume of solution
walang halo
a device used to analyze the chemical composition of small samples at a microscopic scale
microprobe
a type of metallic material composed of three or more elements mixed together in varying proportions
multicomponent na haluang metal
a group of atoms bonded together that behaves as a single unit within a molecule
a test that measures the presence, amount, or activity of a specific substance in a sample, often used in scientific and medical research
baso
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
punto ng balanse
(chemistry) the process of separating a liquid or solution into its parts by passing electricity through it
elektrolisis
(of a solid) to become one with a liquid
natutunaw (sa tubig, atbp.)
to make a solution or mixture weaker or less concentrated by adding more liquid
magbanto
to disperse fine particles throughout a fluid so they remain evenly distributed without settling
magbitin
the process of dispersing or dissolving a substance into a solvent to form a homogeneous solution
solubilisasyon
the arrangement, composition, and characteristics of a material at a microscopic level
microstructure
a tiny, tube-shaped structure made of carbon atoms, with remarkable strength and electrical properties
nanotube
a phase is a distinct form of matter with uniform chemical and physical properties, separated from other forms by boundaries
pagbabago ng isang bagay
denoting substances with a highly organized molecular structure, akin to crystals
mala-kristal
a scientist who studies the structure and properties of crystals
crystallographer
a scientist who studies the chemical composition and processes of celestial bodies to understand the formation and evolution of the universe
cosmochemist
a laboratory technique used to separate and analyze mixtures of substances based on their differential affinities for a stationary phase and a mobile phase
kromatograpiya
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
pagkabulok ng beta
weak attractive forces between molecules or atoms, arising from temporary or induced dipoles
pwersa ni van der waal
a scientist or engineer who specializes in the study and production of metals and alloys, including their properties, processing methods, and applications
metalurhista
the process by which molecules of a substance adhere to the surface of a solid or liquid, forming a thin film or layer
adsorption
a renewable, alternative fuel made from organic materials such as vegetable oils, animal fats, or recycled cooking grease
biodiesel
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
eutectic
a substance capable of absorbing and retaining a large amount of liquid relative to its own mass
