Chemical Equations and Reactions Flashcards
It is the number of atoms of the element found in the substance
Subscript
The sum of the masses of the products is always the same as the sum of the masses of the reactants
Law of Conservation of Mass
Two major parts of Chemical Equations and Reactions
Reactants, Products
They are the new substance
Products
It is the number before the symbol or formula of a substance
Coefficient
They are the starting materials
Reactants
It is the shorthand way of expressing chemical reactions using numbers, symbols, and formula
Chemical Equation
It is a process in which one or more substances, the reactants, are converted to one or more different substances
Chemical Reaction
It states that mass is neither created nor destroyed in any ordinary chemical reaction
Law of Conservation of Mass
It is the process by which chemical change takes place
Chemical Reaction
Substances that change when it is combined with another substance in a chemical reaction
Reactants
