| pure substance the cannot be damaged down into less complicated substances by chemical or physical means. Each aspect has distinct physical and chemical properties. You are watching: What is a chemical substance that cannot be broken down into another chemical substance | |
| compound | a pure substance comprised of atoms of 2 or an ext different aspects joined with each other by chemistry bonds. |
| mixture | a mix of 2 or an ext subtances that are not chemically combined. Not a pure subtance. |
| pure substance | a sample the matter, either a solitary element or a solitary compound, that has definite chemical and also physical properties. |
| physical change | a readjust of issue from one kind to another without a adjust in chemistry properites -- such together a state change, dissolving, crushing, bending, cutting, etc. See more: Which Algebraic Expression Represents The Phrase “Six Less Than A Number”? ? |
| chemical change | a change that occurs when materials are readjusted by the do or break of chemistry bonds into new substances with new properties. |
| law of conservation of matter/mass | matter cannot be created or destroyed; in a chemistry reaction, this means that the number and type of atoms in the reactants need to equal the number and form of atom in the products |
| atom | smallest unit of an facet that still has actually the properties of the element |
| molecule | smallest unit of a compund the still has the properties of that compound; at the very least 2 atom bonded together |
| solution | homogenous mixture of 2 or more substances; example: salt-water |
| dissolving | the process in which corpuscle of building material separate and spread same throughout a mixture |
| homogenous mixture | a mixture v all components evenly mixed throughout; the looks favor on substance |
| heterogenous mixture | a mixture that is an extremely unevenly mixed, different parts the the mixture room visible |
| products | in a chemical reaction, the compounds or aspects that are created by the reaction |
| reactants | in a chemistry reaction, the link or facets that enter into the reaction |
| mass | amount of issue in an objects, measure up in grams or kilograms |
| flammability | a chemical residential property that describes how fine a product reacts come burn through oxygen |
| solubility | a physical residential or commercial property that describes how well a material dissolves into one more material |
