In a word Equation, what is on the Left and Right hand side? | -Reactants sit on the Left side, because they will React with each other to get the...
-Products sit on the Right side because they are the aftermath of the Reaction |
Using a Word Equation, Methane burns in Oxygen giving Carbon Dioxide | Methane + Oxygen = Carbon Dioxide + Water |
What do Symbolic Equations do Differently? | -Simply are the Symbols of the Reactants and Formulas |
Magnesium and Oxygen makes Magnesium Oxide, Show in Symbolic Equation | -2Mg + O2 ---> 2MgO |
Why is Balancing out an Equation important? | -Due to the Conservation of Mass, Matter can't just Disappear or be Created, so Balancing out it out resolves that Issue |
What can State Symbols tell you? | -They can tell you what State the Substance is in
-The 4 ones are
-Solid
-Liquid
-Gas
-Aqueous [Dissolved in Water]
-They come in Symbolic Equations |
What do Ionic Reactions shows? | -This shows what the Ions are making.
-To write one, look at the Reactants and the Products. If its the Same, it can be made redundant |
Write an Ionic Equation doe
CaCl² [aq] +2NaOH [aq] ---> Ca[OH]² [s] + 2NaCl [aq] | -First, Anything that is Ionic, and is Aqueous, break their Ions up, as it will happen in the Reaction
[Ca²+ + 2Cl- + 2Na+ + 2OH- ---> Ca[OH]² + 2Na+ + 2Cl-]
-Getting the Ionic Equation requires to cross out Anything that is the Same. So here, the 2Cl and 2Na can be getting rid off making our equation like:
[Ca²+ [aq] + 2OH- [aq] ----> Ca[OH]² [s] |
What is a Half Equation? | -This is simply showing how Electrons are Transferred in Reactions
-e- = One Electron |
Where can you Write Half Equations? | -Usually only for Oxidation and Reduction |
Can you Combine Half Equations? Use an Example with Sodium/Hydrogen | -Yes, they would make Full Ionic Equations
-Full Equations do not Contain Electrons, as they should be Cancelled out
-Sodium and Hydrogen, it would be 2Na + 2H+ --> 2Na+ +H2 |
