Oxidation- Reduction Reaction

summary:

• Color change
• Solid forms
• Bubbles are produced
• A flame occurs
• Change in temp 

• Reactant  > Product
• Write chemical equation to represent chemical reaction
• Changes way atoms are grouped
• Atoms are neither created or destroyed
• Physical states

          -Solid (s)

          -Liquid  (l)

         -Gas  (g)

         - Dissolved in water (aq)

• Atoms are conserved in a chemical reactions
• Identities of the compound never can be changed
• Subscripts stay the same instead we must add more molecules, we identify these by coefficients
• Coefficient 1 is never written 

You can tell if a chemical reaction occured by, color change, change of form, flame, and temp change. Make sure you always balance equations by adding coefficients because atoms are never created or destroyed.

• The most important reactions are ones that occur in water  (they keep us alive)

         Ex. oxygen you breathe dissolves in your blood.

• Driving forces to make reactants go in the direction of the arrow 

        1 Formation of a solid

        2 Formation of water

        3 Transfer of electrons

        4 Formatiom of gas

• When 2 or more chemicals are brought toget her and any of those things happend a chemical change will occur. 

• process of formation of a solid 

• The soild that forms 

• What the reaction is known as

• If a solid does not conduct electricty but when it dissilves in water does a chemical reaction has occured

• When each unit of a cubstance that dissolves in water produces separated ions.
• when ionic compounds dissolve reamaining solution contains separated ions

1. Knowledge of facts
2. Knowledge of concepts

• means a solid that readily dissolves in water
• Tiny amount dissolves in water naked to eye

Aq solutions are important to us

• Acids-sour 
• Base-bitter/slippery

• Produce H+ ions when dissolved in water    

•  

• When 100 molecules of HCl dissolve in water 100 h+ and 100 Cl- ions are produced
• Hardly and HCl molecules exist in aq

• Substance are strong electrolytes that produce H+ ions

• Substance that produce hydroxide ions (OH-) in water

• Compounds are strong electrolytes that contiam OH- ions
• When strong base + Acids are mixed water is the product

1. The net ionic equation is the same in both cases; water is formed
2. Besides water the second product is an ionic compound which might precipitate or reamain dissolved

• What the ionic compound is known as

Acids and Bases are very different but when mixed together more often that not water is formed because of the H+ and OH- combinnation leaving behind salt.

• The reaction of metal and nometal to form an ionic comound involves the transfer of one or more electrons from the metal to nonmetal.

• A reaction that involves a transfer of electrons
• Metals react with nometal to form an ionic compuond

1. Metal - nonmetal reaction and ionic compound is formed
2. Two nonmetals if they have 02 as a reactant or product. But the compound will not be ionic

• formation of a solid when two solutions are mixed are called preipitation

•  Two anions are simply exchanged. In the products these associationes are reversed. Ex. AB+CD > AD+CB

• Involves H+ ion and end up in the product of water

• The process of electron transfer

Metals and nonmetals form ionic compounds. precipitaion reaction + Double replacement reaction are the same thing where two elements of a compound switch.
