physical change
Physical changes are changes affecting the form of a chemical substance
solubility
Solubility is the property of a solid, liquid, or gaseous chemical substance
endothermic reaction
The definition of endothermic is a chemical reaction that is accompanied by the absorption of heat
chemical property
A chemical property is any of a material's properties that becomes evident during, or after, a chemical reaction
physical property
A physical property is any property that is measurable, whose value describes a state of a physical system
exothermic reaction
An exothermic reaction is a chemical reaction that releases energy by light or heat
boiling point
Boiling is the rapid vaporization of a liquid
chemical change
Chemical changes occur when a substance combines with another to form a new substance
subscript
In chemical formulas the number of atoms in a molecule is written as a subscript
Acid
Lysergic acid diethylamide, also known as acid, is a psychedelic drug known for its psychological effects
law of conservation mass
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed
rate of change
The rate of change is a rate that describes how one quantity changes in relation to another quantity
coefficient
a coefficient is a constant term related to the properties of a product
catalyst
a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change
Reactant
a substance that takes part in and undergoes change during a reaction.
ductile
able to be deformed without losing toughness
malleable
able to be hammered or pressed permanently out of shape without breaking or cracking.
product
an article or substance that is manufactured or refined for sale
Base
are substances that, in aqueous solution, are slippery to the touch, taste astringent, change the color of indicators
dissolving
become or cause to become incorporated into a liquid so as to form a solution.
reactivity
chemical substance undergoes a chemical reaction
combustion
is a high-temperature exothermic redox chemical reaction between a fuel and an oxidant
surface area
is a measure of the total area that the surface of an object occupies
pH
is a scale of acidity from 0 to 14
flammability
is the ability of a substance to burn or ignite, causing fire or combustion
precipitate
something that happen suddenly, unexpectedly, or prematurely.
concentration
the number of grams in a particular volume
melting point
the temperature at which a given solid will melt
