Predicting Products Identify the type of reaction Use the general formula and label the parts of the equation Predict the products using the general equation

Predicting Products - TYPES Synthesis A + B  AB Decomposition AB  A + B Single Replacement AX + B  BX + A Double Replacement AB + CD  AD + CB Combustion Carbon cmpd + O2  CO2 + H20 + energy! Acid Base Acid + Base  Water + Salt HCl + NaOH  H2O + NaCl

Type I: Synthesis 2 H2O(l) To recognize: 2 pure elements (though may be diatomic) O2 (g) + 2H2(g)  To predict: Use SOCS to write formula of one product. Remember that the cation comes first! 2 H2O(l)

Type II: Decomposition To recognize: 1 compound as a reactant H2O (l) → To predict, break apart into elements (be sure to check for diatomics: H, N, O, F, Cl, Br, I) O2 (g) + H2(g)

Type III: Combustion To recognize: First 3 elements will be CHO C3H8 (g) + O2(g)  To predict: Always remember that CO2 and H2O are the products! 3CO2 (g) + 4H2O(l) 5

Remember 2 or more simple products Type of reaction? CaO (s)  2 Ca + O2 (g) 2

Look at reactants Type?? C6H6 (l) + O2(g) 12 CO2 (g) + 6 H2O(l) 2 15

Remember one product! What type? Al(s) + Cl2(g) 

Type IV: Single Replacement To recognize: 1 single element, and 1 compound Zn (s) + HCl (aq)  To predict, check to see if reaction happens (activity series). If the reaction will happen then use SOCS to recombine into a new compound. The other element will be by itself (check for diatomic)

No Reaction Type? What Happens??? Cu(s) + FeSO4(aq)  Zn (s) + HCl (aq)  ZnCl2 (aq) +H2 (g) No Reaction

Type V: Double Replacement To recognize: 2 compounds are reacting AgNO3 (aq) + CaCl2(aq) → To predict: Ions switch places and use SOCS to form new compounds. Check solubility chart for states of matter. (outies then innies, cations always comes first) AgCl(aq) + Ca3(NO3) 2(aq)

Solubility

Type VI: Acid-Base K2SO4(aq) + H2O To recognize: Acids start with H, Bases end with OH (though acid does NOT need to be the first reactant listed) H2SO4 (aq) + KOH (aq)  To predict: Just like a Double Displacement, the ions will swap partners. As a result, H2O is always produced, along with another ionic compound (so use your SOCS), which is called a salt. K2SO4(aq) + H2O

Type???? Outie /Innie H3PO4(aq) + Ca(OH)2 (aq) H2O(l) + Ca3(PO4)

Type, Predict, and Balance CO2(g) + H2O C4H10(g) + O2(g)  Mg (s) + H3PO4(aq)  Pb(NO3)2 (aq) + NaCl(aq)  SrCl2 (s)  Mg3(PO4)2(aq) + H2 Pb(Cl)2 +NaNO3 Sr + Cl2
