Chemistry Intro Stuff
____________________ is the study of matter and energy. - ✅✅-Chemistry
What are the three parts of chemistry? - ✅✅-composition, structure, process/reactions
What is composition? -✅✅-what something is made of
What is structure? - ✅✅-how something is put together
Chemical processes always undergo a ____________________. - ✅✅-state change
What are the two kinds of energy changes? - ✅✅-endothermic and exothermic
What is an endothermic reaction? - ✅✅-absorbs energy (cold pack)
What is an exothermic reaction? - ✅✅-releases energy (hot hands, glowsticks)
In what state of matter do the particles move slowly and are very close? - ✅✅-solid
In what state of matter is the more space and more movement of particles? - ✅✅-liquid
In what state of matter are the particles very far apart and move at high speeds? - ✅✅-gas
A ____________________ includes energy changes and matter changes. - ✅✅-reaction
What is a reactant? - ✅✅-the matter present before a reaction
What is a product? - ✅✅-the matter produced from a reaction
What is matter? - ✅✅-it has mass and takes up space (volume)
What is an element? - ✅✅-the simplest pure substance made of only one kind of atom that
cannot be broken into simpler matter
What is an atom? - ✅✅ -the smallest unit of an element that has all the propertie and
characteristics of the element
✅✅
____________________ can be observed without altering or changing the identity of the
matter. - -physical properties
What are some examples of physical properties? - ✅✅-color, hardness test, melting point,
boiling point
What is an extensive physical property? - ✅✅-depends on the amount of matter present
What is an intensive physical property? - ✅✅-does not depend on the amount
