(24 cards)
What is a product?
A substance that forms in a chemical reaction
What is reactant?
A substance or molecule that participates in a chemical reaction
What is a chemical energy?
The energy released when a chemical compound rest s to produce new compounds.
What is a exothermic reaction?
Chemicals reaction that requires heat
Example- making ice cubes
What is a endothermic reaction?
A chemical reaction that reacquires heat
Example- melting ice
What is synthesis reaction?
A reaction in which two or more substances combine to form a new compound.
What is decomposition reaction?
A reaction in which a single compound breaks down to form two or more simpler substances.
What is electrolysis?
The process in which an electric current is used to produce a chemical reaction, such as decomposition of water.
What is combustion reaction?
The oxidation reaction of an organic compound, in which heat is released.
What is a single-displacement reaction?
A reaction in which one element or radical takes the place of another element of radical Ina compound.
What is a double-displacement reaction?
A reaction in which a gas, a solid precipitate, or a molecular compound forms from the apparent exchange of atoms or ions between two compounds.
What is a oxidation-reduction reaction?
An chemical change I which one species is oxidized and another species is reduced also called redox bonding.
What is radicals?
An organic group that has one or more electrons available for bonding.
What is reduced?
Substances that accost electrons
What is oxidized?
Substances that give up electrons
What is chemical equation?
A representation of chemical reaction that uses symbols to show the relationship between the reactants and the Products.
What is a mole ratios?
The relative number of miles of the substances required to produce a given amount of product in a chemical reaction.
What is a coefficient?
An equations that can be balanced only by putting numbers in front of the chemical formulas.
What is law of conservation of mass?
The total mass of the reactants is always the dames as the total mass of the products.
What is law of definite proportions?
No matter what amounts of magnesium and oxygen are combined or how the magnesium oxide is made, the balanced question does not change.
What is a catalyst?
A substance that changes the rate of chemical reaction
What is enzyme?
A type of protein that speeds up metabolic reactions.
What is a substrate?
Substance or element that lies
What is a chemical equilibrium?
A state balance in which the rate of a forward reaction equals the rate of the reverse reaction
