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.

The spacing is kinda weird the 1st one goes by 2 and the second by one
