Question | Answer |
Simplest form of matter | Element |
The smallest partical of an element | Atom |
Atom that makes another atom different | element has different properties |
is 2 or more particals connected together | molecule |
a substance in which 2 or more elements are held together by a chemical bond | compound |
anything that takes up space | matter |
3 phases of mattter | solid, liquid, and gas |
are close together and can only vibrate | solid |
such as water, they are farther apart and move more freely | liquid |
such as air, particals are far apart and free to move in every direction | gas |
the matter that has a definite shape and volume | solid |
the matter that fill a container and has no shape, but has volume | liquid |
the matter that has no definite shape and volume | gas |
is when the particles in the solid ice cube gain energy and vibrate faster, they break apart and become liquid water | solid to a liquid/melting point |
the molecules move in a solid | move slow |
the molecules move in a liquid | move medium |
the molecules in a gas | move really fast |
is when the particals in water have enough energy to brak away and become liqiud water | liquid to a gas/boiling point |
is when the particals don't have enough energy and start to come together | liquid to solid/freezing point |
is 2 things,particals combines stay individual and yes you can see them | mixture |
is when 2 or more things mix but you can see one substance but not the other | solution |
examples of solution | sugarwater and salt water |
a substance that disolves other matter | solvent |
a substance that is disolved | solute |
a solution that has a small solute compared to the amount of sovent | dilute solution |
a large amount amount of solute compared to the amount of solvent | concentrated solution |
a substance that undergoes a chemical reaction often by combining with another substance | reactant |
a substance that is formed in a chemical reaction | product |
combining oxygen and hydrogen to form water another is wood burning | some signs of chemical change |
lightening bugs, burning wood, and rust | examples of chemical reactant |
chemical reaction in which more energy is given off than taken in | exothermic reaction |
chemical reaction in which more energy is taken in than is given off | exdothermic reaction |
arrangement of symbols and formulas used to show what happens during a chemical reaction | chemical equation |
compound that releases hydrogen ions in water | acid |
atom that contains acid in them | hydrogen |
a process in which an acid and a base react to produce a salt and water | neutralization |
set of numbers between 0 - 14 used to measure the strength of acids and bases | ph scale |
arrangement of symbols that shows both the kinds and number of atoms in a compound | formula |
compound that releases hydroxide ions when dissolved in water | bases |
substance that changes color at the certain range of ph values | indicator |
cleaning products and ammonia | examples of srong bases |
drain cleaners,liquid soap and sea water | charteristics of bases |
baking soda and antacids | examples of weak bases |
