Flood Chemistry

chemical change

a process involving one or more substances changing into new substances

chemical property

the ability or inability of a substance to combine with or change into one or more new substances


a technique that is used to separate the components of a mixture based on the tendency of each component of a mixture to travel or be drawn across the surface of another material


a chemical combination of two or more different elements; can be broken down into simpler substances by chemical means and has properties different from those of its component elements


a separation technique that produces pure solid particles of a substance from a solution that contains the dissolved substance


a technique that can be used to physically separate most homogeneous mixtures based on the differences in the boiling points of the substances involved


a pure substance that cannot be broken down into simpler substances by physical or chemical means

extensive properties

a physical property, such as mass, length, and volume, that is dependents upon the amount of substance present


technique that uses a porous barrier to separate a solid from a liquid


a form of matter that flows to conform to the shape of its container, fills the container's entire volume, and is easily compressed

heterogeneous mixture

one that does not have a uniform composition and in which the individual substances remain distinct

homogeneous mixture

one that has a uniform composition throughout and always has a single phase

intensive properties

a physical property that remains the same no matter how much of a substance is present

law of conservation of mass

states that mass is neither created nor destroyed during a chemical reaction

law of definite proportions

states that, regardless of the amount, a compound is always of the same elements in the same proportion by mass

law of multiple proportions

states that when different compounds are formed by the combination of the same elements, different masses of one element combine with the same mass of the other element in a ration of small whole numbers


a form of matter that flows, has constant volume, and takes the shape of its contained


a physical blend of two or more pure substances in any proportions in which each substance retains its individual properties; can be separated by physical means

percent by mass

a percentage determined by the ratio of the mass of each element to the total mass of the compound

periodic table

a chart that organizes all known elements into a grid of periods and families arranged by increasing atomic number

physical changes

a type of change that alters the physical properties of a substance but does not change its composition

physical property

a characteristic of matter that can be observed or measured without changing the sample's composition


a form of matter that has its own definite shape and volume, is incompressible, and expands only slightly when heated


a uniform mixture that may be contain solids, liquids, or gases

states of matter

the physical forms in which all matter naturally exists on earth


a form of matter that has a uniform and unchanging composition


gaseous state of a substance that is a liquid or a solid at room temperature
