CH 10: balancing chemical equations Flashcards
VOCAB: Solvent
Has the ability to dissolve other substances
VOCAB: Synthesis Recation
A chemical reaction in which two or more substances react to yield a single product
VOCAB: Chemical equation
A statement using chemical formulas to describe the identities and relative amounts of the reactants and products involved in a chemical reaction.
VOCAB: Single replacement reaction
A chemical reaction that occurs when the atoms of one element replace the atoms of another element in a compound.
VOCAB: Decomposition reaction
A chemical reaction that occurs when a single compound breaks down into two or more elements or new compounds.
VOCAB: Coefficent
In a chemical equation, the number written in front of the formula.
VOCAB: Solute
The minor component in a solution, dissolved in the solvent.
VOCAB: precipitate
A solid produced during a chemical reaction in a solution.
VOCAB: Aqueous solution
A solution in which the solvent is water.
VOCAB: Double replacement
A chemical reaction that involves the exchange of positive ions between two compounds dissolved in water.
What law is blancing equations based on?
Law of conservation of mass (antoine Lavoisier)
Rules of balancing equations
- do not change subscript
- no frations
- write all ones
Hints in balancing equations
- if you have even:odd then double the odd side
- balance polyatomic ions as a group
- balance oxygen last
- double check
Single displacement
ID key: one lonely atom replaces another
Double displacement
ID key: everything swaps
