The Science of Chemistry - Chapter 1

any substance that has a definite composition

the process by which one or more substances change to produce one or more different substances

the physical forms of matter, which include solid, liquid, gas, and plasma

a substance or molecule that participates in a chemical reaction

a substance that forms in a chemical reaction

Anything that has mass and takes up space

A measure of the size of a body or region in three-dimensional space

A measure of the amount of matter in an object

A measure of the gravitational force exerted on an object.

something that has magnitude, size, or amount

a quantity adopted as a standard of measurement

a ratio derived from the equality between two different units that can be used to convert from one unit to the other

a characteristic of a substance that does not involve a chemical change, such as density, color, or hardness

the ratio of the mass of a substance to the volume of the substance

a property of matter that describes a substance's ability to participate in chemical reactions

the smallest unit of an element that maintains the properties of that element

a sample of matter, either a single element or a single compound, that has definite chemical and physical properties

a substance that can't be separated or broken down into simpler substances by chemical means

the smallest unit of a substance that keeps all of the physical and chemical properties of that substance

a substance made up of atoms of two or more different elements joined by chemical bonds

a combination of two or more substances that are not chemically combined

describes something that has a uniform structure or composition throughout

composed of dissimilar components

change in 1 or more physical properties without a change to chemical properties

changes into entirely new substance

reactivity, flammability, toxicity, corrosive

color, size, melting point, boiling point, density, ductile

study of the compositions of matter and the changes that matter undergoes

substances that can be seen or touched

smaller particles that make up matter, need microscope to been seen

includes two of the same element

T/F: elements are pure substances

a mixture containing particles that settle out if left undisturbed

mid-size particles that do not settle out

a mixture containing atoms, ions, or molecules fully dissolved

dissolving medium

"stuff" being dissolved
