Chemistry
-
-
(a) atoms combine in a multitude of ways to produce pure substances which make up all of the living and nonliving things that we encounter,
(b) atoms form molecules and compounds that range in size from two to thousands of atoms,
-
Analyze data on the properties of substances before and after they interact to determine if a chemical reaction occurred
Chemical Property
Chemistry. a property or characteristic of a substance that is observed during a reaction in which the chemical composition or identity of the substance is changed:
Physical Change
a usually reversible change in the physical properties of a substance, as size or shape.
-
Physical Property
a property (as color, hardness, boiling point) of matter not involving in its manifestation a chemical change
Chemical Change
Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances
-
(LT2) Use a model to explain that atoms are rearranged during a chemical reaction to form new substances with new properties. Explain that the atoms are all present in the products and thus the total number of atoms is conserved.
-
According to the Law of Conservation, all atoms of the reactant must equal to the atoms of the product.
