T3 Exam- Mr.Sluiter Flashcards
(26 cards)
Chemical Reaction
A chemical change or reaction takes place on an atomic level and produces a new substance.
Corrosion
Any chemical change that causes a material to be worn away.
Mass
The amount of matter within a substance or an object. The tool used to measure mass is the balance scale and units of measure used for mass are milligrams and grams.
Temperature
A measure of the average kinetic energy in molecules.
Matter
Anything that has mass and volume.
Solubility
The ability of a substance to dissolve in water. It is a characteristic property of substances.
Molecule
A substance made when two or more like or unlike atoms bond.
Compounds
Are made up of different kinds of elements; the elements that make up the compound form a new substance with different properties. Ex: water is a compound made of hydrogen atoms and oxygen atoms.
Conservation of matter.
It states that matter cannot be created or destroyed in a chemical change, it can only change forms. The same overall amount of matter is present before and after the chemical change.
Mixtures
Are made up of substances that remain the same substance; they can be separated into their individual parts and keep their original properties. Ex: Salt water is a mixture that can be separated into salt and water.
Chemistry
The study of matter and how matter behaves or changes.
Reversed!
A chemical change or reaction takes place on an atomic level and produces a new substance.
Chemical Reaction
Volume
The amount of space taken up by a substance or an object, regardless of its shape. Volume is measured in units of millimeter (mL) and liter (L).
Element
is a substance that is made up of only one kind of atom. Elements cannot be broken down by chemical reactions.
Rusting
A form of oxidation and corrosion of iron and iron alloys. These undergo chemical reations when exposed to water and oxygen.
Density
Is the amount of mass of a substance in a specific volume, calculated by mass divided by volume.
