Chemical Reactions

1.The Basics of Chemical Reactions The outermost Electrons are only affected in Chemical

Reactions.Example-The Valence Electrons are affected during

Chemical Reactions

A Chemical Reaction is a change in which a substance is changed into one or more new substances.Also,bonds are being broken and created www.wikipedia.org/wiki/chemical_reaction

Example-When you mix Hydrogen and Chloride in an Ammonia test tube, you get Ammonium Chloride www.answers.com/topic/chemical-reaction

H2+O2=H2O www.wildeboer-fitch.wikispaces.com

http://wiki.answers.com/Q/The_parts_of_the_atom_that_are_involved_in_chemical_reactions_are_the_what

A reactant is a substance or compound consumed during a Chemical Reaction

Example-When Hydrogen burns in Oxygen forming Water the reactants are Hydrogen and Oxygen www.wikipedia.org/reactants

Five signs of a Chemical Reaction are:1.Change of Color 2.Formation of Gas 3.Formation of precipitate 4.Change of temperature 5.Energy produced

www.wikianswers.com/chemicals

Chemical Reactions relates to the law of Conservation and Mass because the law of conservation of mass states in both you have the same amount of products before the reaction and after the reaction www.wildeboer-fitch.wikispaces.com

Example-When water is coming out of a faucet, it is fat on top and slim on the bottom

Example-If a solid turns into a liquid,the mass stays the same. www.wikipedia.org/wiki/conservationofmass

2.Energy and Chemical ReactionsChemical potential energy is energy possesed by an

object because of its position www.psd70.ab.ca/sghs/Sct10/potent

Example-A massive ball of a demolition Machine or a stretched bow. www.wikipedia.org/wiki/chemical_potential_energy

Activation energy is energy that must be overcome so that a Chemical Reaction can take place

Example-Sparks are made by striking steel against a

flint.

2.Energy and Chemical ReactionsYou start a Chemical Reaction by mixing two

chemicals that don’t mix well together. www.wikipedia.org/wiki/reactions

Exothermic reaction describes a process that releases energy usually in the form of heat, light,electricity,or sound

Example-Condensation of rain from Water Vapor www.wikipedia.org/wiki/exothermic_reactions

2.Energy and Chemical Reactions•Endothermic Reactions is a process that

absorbs energy in the form of heat.•Example-Mixing water with potassium

chloride •www.wikipedia.org/wiki/endothermic_reac

tions

3.Types of Chemical Reactions

Synthesis is a process which combines together two or more pre-existing elements resulting in the formation of a new one. www.wikipedia.org/wiki/synthesis

3.Types of Chemical ReactionsDecomposition is the separation of a

chemical compound into an element.Example-An example of decomposition is that

of Hydrogen Peroxide which will slowly decompose into water and oxygen www.wikipedia.org/wiki/decomposition

Combustion is a complex sequence of exothermic chemical reactions between a fuel and an oxidant.

Example-In the combustion of Hydrogen and Oxygen, the result is Water Vapor www.wikipedia.org/wiki/combustion

A single displacement reaction is when an element moves out of one compound and into another.

Example-The reaction between Magnesium and Hydrochloric acid forms Magnesium Chloride. www.wikipedia.org/wiki/single_displacement_reaction

A double displacement reaction is an exchange of bonds between two reacting chemical species.

An example of a double displacement reaction

An example of Combustion www.wikipedia.org/wiki/combustion

An example of Chemical synthesis (Iron rusting) www.wikipedia.org/wiki/chemical_synthesis

4 Fe + 3 O2 → 2 Fe2O3 (iron rusting)
