| A | B |
|---|
| Ionic | Metal and Nonmetal - giving and taking |
| Covalent | Non Metal and Nonmetal - sharing |
| Types of chemical reactions | Synthesis. A+B → AB |
| Types of chemical reactions | Decomposition. AB → A + B |
| Types of chemical reactions | Single displacement. AB +C → A + BC |
| Types of chemical reactions | Double displacement. AB + CD → CB + AD |
| Types of chemical reactions | Combustion. Fuel +O2→ H2O+CO2+Energy |
| Homogeneous | A mixture that looks uniform even under microscope. Very small particles. A solution is a homogeneous mixture. |
| Heterogenous | are not evenly mixed and do not have a fixed composition. A suspension is a heterogeneous mixture. Large particles that can be evenly dispersed. Particles will settle out. |
| Neutralization | when an acid and a base react. H3O+ + OH---> H2O. Neutralization products are water and salt. Salts form from spectator ions- The non hydroxide or hydronium ions. |
| Spectator ions | They watch the neutralization occur |
| Properties of acids and bases | Acids GIVE protons Bases take in the protons |
| Ionic Bond | the bond formed when oppositely charged ions attract |
| Ionic Bond | formed from the transfer of valence electron |
| Ionic Bond | dissolved in water will conduct electricity |
| Covalent Bond | bonds formed when electrons are shared between two atoms. Generally forms between two nonmetals |
| Hydrogen Bond | attractive interaction of a hydrogen atom with an electronegative atom, such as nitrogen, oxygen or fluorine, that comes from another molecule. |
| Supersaturated solutions | Can only occur when heat is applied |
