Down: 1) a physical blend of two or more pure substance in any proportion in which each substance retain its individual properties can be separated by physical means2) states that a compound is always composed of the same elements in the same proportion by mass4) gaseous state of a substance that is liquid or a solid at room temperature6) a form of matter that flows to conform to the shape of its container, fills the volume , and is easily cpmpresser8) a seperation technique that produces pure solid particles of a substance form a solution that contains the dissolved substance11) a form of matter that flows , has constant volume , and takes the shape of its container13) a pure substance that can not be broken down into simpler substances by physical or chemical merge16) a type of change that alters the physical properties of a substance but does not change its composition18) a technique taht can be used to physically separate most homogeneous mixtures based on the differences in the boiling points of the substance involved20) a uniform mixture that may contain solids, liquids, or gases , also called homogenous mixture Across: 3) the physical form in which all matter naturally exists on Earth-Most commonly as a solid a liquid or a gas5) states that when different compounds are formed by the combination of the same elements, different mass of one element combine with same mass of the other element7) a chart that organizes all known elements into a grid of horizontal rows (periods) and vertical colums ( groups or families) arranged by increasing atomic number9) one that does not have a uniform compostionm and in which the individual substances remain distinct10) the ability or inability of a substance to combine with or change into one or more new substances12) a form of matter that has its own definite shape and volume, is compressible and expands only slighty when heated14) a technique that is used to sepearte the components of a mixture based on the tendency of each component to travel or be drawn across the surface of another materials15) a physical property such as mass length , and volume , that is dependent upon the amount of substance present17) one that has a uniform compostion throughout and always has a single phase19) a form of matter that has a unifrom and unchanging compostion also known as a pure substance21) a characteristic of matter that can be observed or measured without changing the sample's comopostion for example, density, color taste hardness , and melting point22) a physical property that remains the same no matter how musch of as substance is present23) a percentage determined by the ratio of the mass of each element to the total mss of the compound24) a technique that uses a porous barrier to separate a solid from a liquid25) states that mass is neither created nor destroyed during a chemical reaction but is conserved26) a process involving one or more substance changing into new substances also called a chemical reaction27) a chemical combination of two or more different elements , can be broken down into simpler substances by chemical means and has properties different from thes of its's components
