chemical property correct answer: the way substances may change/react to become another substance physical property correct answer: can be observed without any change to identification and/or composition matter correct answer: anything that has mass and occupies space reactivity, stability, flammability, toxicity, fermentation correct answer: examples of chemical properties malleability, ductility, conductivity, viscosity, boiling/melting point correct answer: examples of physic...

Chemistry - correct answer Study of matter -composition -structure -energy changes it goes through Matter - correct answer -is all around us -can be identified by its physical or chemical properties -any substance regs takes up space (volume) and has mass Atom - correct answer Most simple form of matter Element - correct answer -homogenous -cannot be broken down simpler by physical or chemical means -atomic numbers -periodic tables -represented by one or two letters Compound...

Chem 161 Lecture 2 Answers 2023 UPDATE RATED A+ How can matter be classified? Matter: Purity: 1. Pure Substances A. Elements B. Compounds 2. Mixtures A. Homogenous Solutions B. Heterogenous Solutions What are the differences between compounds and mixtures? Compounds: 1) Definite Composition (with exact chemical formula) 2) Have different properties than the elements making up the compound (H20 is liquid compared to H2 and O as gases) 3) Can be separated into its elements only by chemic...

matter - ️️objects that take up space and have mass. made up of elements. physical thermal electrical and chemical properties (color, density,hardness,conductivity) elements - ️️substances that cannot be broken down into simpler substances by chemical means. atoms&molecules - ️️everything in the physical world is make up of microscopic matter comprised of atoms or molecules. homogenous matter - ️️properties are the same throughout. coal and glass are examples heteroge...

Fahrenheit - 1.8(C) + 32 Celsius - (F-32)/1.8 Physical property - properties can be observed without changing the identity of the substance under observation Chemical property - properties can only be observed during a change int he identity of the substance under observation examples of chemical properties - corrosive, combustible, mutagenic, teratogenic, explosive examples of physical properties - size, malleability, ductility, conductivity, density, state of matter Homogenou...
