Chemistry of Living Things

Compound More than one type of atom in fixed proportions bonded together
Chemical Changes A new product is formed and the reaction cannot be reversed
Element One type of atom-a pure substance that cannot be broken down.
Physical change A change of state (liquid, solid, gas) , size or shape
Endothermic Heat is absorbed in the reaction ( gets colder)
Exothermic Heat is produced /released in the reaction (gets hotter)
Concentration The amount of solute dissolved in the solvent
Reactant Chemicals which are reacting
Product The result of a reaction
Solution A chemical has dissolved- combined
Mixture Two chemicals mixed but not combined or in a fixed proportion
Enzyme Speeds up a reaction
Solute The substance that is dissolving
Solvent The solution a substance is dissolving in
Dissolve Substance absorbed into a solution
Chemical reaction Making or breaking chemical bonds
Reaction rate The speed of a reaction
Conservation of Mass No mass is gained or lost in a chemical reaction- same number of atoms, before and after the reaction
Ionic Compound Compound made up of a metal and a non metal
Covalent compound Compound made of at least 2 non metals
Ionic Bond Bond between a metal ion (cation) and a non metal ion (anion)
Ion Charged atom formed from loss or gain of electrons
Respiration A chemical reaction that happens in all living things. Rate is slow and controlled release of energy.
Combustion A chemical reaction where a substance reacts with oxygen and gives off heat. Rate is fast with rapid release of energy.
Chemical equations Show reactants, and products of a reaction
Catalyst Speeds up a reaction without actually taking part in the reaction
Factors effecting reaction rate temperature, surface area, concentration, catalyst
