Drill Describe the type of reactions below: 1. C6H12O6 + O2 --> CO2 + H2O 2. N2O5 + H2O --> HNO3 Mg(OH)2+ HCl --> MgCl2 + H2O KCl+ F2 --> KF + Cl2
Combination Reaction: two elements combine to form one molecule A + B --> AB Ex: N2O5 + H2O --> HNO3 Decomposition Reaction: a molecule breaks apart into two elements AB--> A + B Ex: NaN3 --> Na + N2 Combustion: add oxygen and form CO2 and water A + O2 --> CO2 + H2O Ex: C3H8 + O2 --> CO2 + H2O Single Replacement: the anion switches with the single element AB+ C --> CB + A Ex: HCl + Mg --> MgCl2 + H2 Double Replacement: anions switch places with each other AB+ CD --> AD + CB Ex: AgNO3 + K2SO4 --> Ag2SO4 + KNO3
Diatomic Molecules: Some elements cannot exist by themselves, even when they are isolated from any other type of atom. Elements of this nature will combine with atoms of the same element in order to be stable. Diatomic Molecules- elements that occur in twos H, O, F, N,Cl, Br, I
Given the following word equation, write the correct symbol equation. Give the type of reaction, then balance it! 1. magnesium + oxygen --> magnesium oxide 2. hydrogen + oxygen --> dihydrogen monoxide
3. sodium iodide + potassium nitrate --> sodium nitrate + potassium iodide 4. Lead (II) Nitrate + PotassiumIodide --> leadiodide + potassium nitrate 5. Iron (III) Nitrate + Potassium Thiocyanate --> ??
