Section 3

every chemical reaction involves a change in energy some reaction absorbs energy and other realses it

The rate of a chemical reaction can be controlled by such factors ad concentration surface area temperature and use of a catalyst or inhibtor

Section 1

Matter may be in the form of elements compounds or mixtures.

chemical changes result in the formation of new substances physical changes do not

color changes prosecution of a gas or a precipitate a change in temperature or a change in the properties of a substances are all clues that a chemical reaction has taken place

Chemical reaction occurs when chemical bonds are formed or broken

Section 1 vocab

Chemistry:The study of the properties of matter and how matter changes

Element:A substance that can not be broken down into any other substances by chemical of physical means.

Compound: Is a substance made of two or more element chemically combined in a specific ratio, or porportion

Mixture: Is made from two or more pure substances elements, compounds, or both that are the same place but not combined as a new material.

Solution: Is a well mixed mixture

Physical change:A change that alters the form or appearance or a material but does not make thhe materiel into another substance

Chemical change:A change in matter that produces a new substance.

Chemical reaction:The process in which substances undergo chemical changes that result in the formation of new substances

Precipitate:A solid that forms form a solution during a chemical reaction

Atom:the smallest particle or an element

Molecule:the combination of two or more atoms

Chemical bond:The force that holds atoms together

Section 2 vocabulary

Chemical equation:A short easy way to show a chemical reaction using symbols instead of words

symbols:A one or two letters set of charters that is used to identify elements

Chemical formula:A combination of symbols that represent the element in a compunds

Subscripts: A number in a formula written lower and smaller than the symbol to indicate the number of atoms of an element in a molecule.

reactants:A substances that enters into chemical

Products:a substances formed as a result of a chemical reaction

Conservation of mass:The principle starting that matter is not created or destoryed during a chemical reaction

Coefficient:A number informant of a chemical formula in a equation that indicates how many molecules or atoms

Synthesis:A chemical reaction in which two or more simple substances combine to form a new more complex substance

Decomposition:A chemical reaction that brakes down compound into simpler products

Replacement reaction:A reaction in which one elements repales another in a compund or when two elements in diffrent compunds tradde places

Section 3 Vocabulary

Exothermic reaction:A reaction tht relases energy in the form of heat

Endothermic reaction:A reaction that absorbs energy in the form of ehat

Activation energy:The minimum amount of energy that has to be added to get a chemical reaction started

Concentration:The amount of one material in a certain volume of another material

Catalyst:A material that increases that rate of a chemical reaction by lowering the activation energy

enzyme:A biological catalyst that lowers the activation energy of reaction in cells

inhibitor:A material that decresses the rate of a reaction

Section 2

A chemical equation uses symbols to show the reactions and products of a chemical reaction

Matter is neither created nor destroyed during a chemical reaction

Chemical reaction may be classified by the types of changes in reactants and products

Section 4

The fire triangle shows the three things necessary to start a fire and keep it burning fuel air and heat

Water stops combustion by keeping the fuel from coming in contact with oxygen also evaporation of water uses a great deal of what and cools the fire

Section 4 vocab

Combustion: A rapid reaction between oxygen and fuel that rustults in fire

fuel:A material that relases energy when it burns

Video: Water,and salt are forms of compounds

We have millions of substances on our planet because the atoms are able to combine to form new substances called compounds.

Chemical Formulas: NaCl is a chemical formula of table salt

Neon is rarely found in a compound.

Noble gases have 8 valance electrons while the other elements have 1-7 valance electrons.
