| The five basic reaction types are |
answer
| Synthesis, Combustion, Decomposition,Single replacement, double replacement |
question
| Synthesis |
answer
| two or more reactants join together to form one single product example 2Na+Cl2>2NaCl |
question
| Decomposition |
answer
| one single reactant, compound produces two or more products AB> A+B |
question
| Combustion reactions |
answer
| oxygen reacts with another substance often producing energy in the form of heat and light General form Cx hy(oz) +02> CO2+ H20 |
question
| Single Replacement |
answer
| Atoms of one element replace the atoms of another element that is part of a compound- in other words an element + a compound yields a new element + new compound general form: AX + B> BX + A OR AX +Y> AY + X A AND B ARE METALS OR HYDROGEN AND X,Y ARE NON METALS |
question
| Double Replacement |
answer
| an exchange of cations (+ions) between two ionic compounds AB + CD> AD + CB |
question
| what is a precipitate |
answer
| it is insoluble or slightly soluble in water. A solubility chart can help determine this |
