EQUATIONS AND DIAGRAMS

Diagrams & Balanced Equations: You need to be able to draw &/or identify balanced equations using models Ex. H2O Ex. Cl2 Hydrogen Oxygen Chlorine

+  Ex. #1 C + O2  CO2 Given the balanced equation, A model of this equation is… +  Let: represent C represent O

+  Ex. #2 2Mg + O2  2MgO Given the balanced equation, A model of this equation is… +  Let: represent Mg represent O

Ex. #3 Draw a model for the following reaction: Mg + 2HCl  H2 + MgCl2 +  + Let: represent Mg represent H represent Cl

+  + Ex. #4 LiOH + HF  LiF + H2O Let: represent Li represent H Draw a model to represent the neutralization reaction below. LiOH + HF  LiF + H2O +  + Let: represent Li represent H represent O represent F

+  + Ex. #5 Mg(OH)2 + 2HCl  MgCl2 + 2H2O Draw a model to represent the neutralization reaction below. Mg(OH)2 + 2HCl  MgCl2 + 2H2O +  + Let: represent Mg represent H represent O represent Cl

Ex. #6 Which model correctly represents the balanced equation below? 2H2 + O2  2H2O Let: represent H represent O A +  B + +  C + 
