Unit 5 Chemical Reactions Flashcards
The process where elements and/or compounds interact with one another to form new substances
Chemical reaction
An equation that uses chemical formulas and symbols to show the reactants and the products in a chemic reaction
Balanced Chemical equation
A reaction of at least two reactants that produce one product
Synthesis reaction
A reaction in which one compound is broken down into two or more products.
Decomposition reaction
A chemical reaction in which a free element replaces an ion in a compound
Single replacement reaction
A chemical reaction where to compounds change partners
Double replacement reaction
A reaction in which energy is transferred to the reactants from the surroundings usually in the form of heat energy is absorbed feels cooler
Endothermic reaction
A reaction that transfers energy from the reactants to the surroundings usually As heat energy is released feels warmer
Exothermic reaction
A substance that changes the rate of a chemical reactions without being consumed or changed itself
Catalyst
A solid product that is created during a chemical reaction
Precipitate
A short hand notation for a compound or element using chemical symbols and numbers
Chemical formula
A short hand description of the chemical formulas and symbols in a reaction
Chemical equation
The starting materials in a chemical reaction
Reactants
The substances formed from a chemical reaction
Products
A number placed in front of the chemical formulas in a reaction to balance the number of atoms on both sides
Coefficient
A law that states that mass is neither created nor destroyed in ordinary chemical and physical changes
Law of conservation of mass
The minimum amount of energy need it for substances to react
Activation energy
The law that states that energy is neither created nor destroyed
Law of conservation of energy
A substance that slows down or stops a chemical reaction
Inhibitor
