Honors Chemistry Name _________________________________ Chapter 7: Types & Balancing Chemical Reactions Worksheet I Date _____/_____/_____ Period ______ 1. A decomposition reaction starts with one reactant and ends up with two or more products. Which of the following reactions are decomposition reactions? Circle the letter and balance the circled reaction. ____ Na a. ____ NaCl b. ____ Na d. ____ H2 ____ NaCl + ____ Cl2 ____ H2 c. ____ H2O + ____ O2 e. ____ NaOH + ____ Cl2 + ____ O2 ____ H2O ____ HOH + ____ HCl + ____ NaCl 2. A synthesis reaction starts with two reactants and ends up with one product. Which of the following reactions are synthesis reactions? Circle the letter and balance the circled reaction. ____ Na a. ____ NaCl b. ____ Na + ____ HCl c. ____ H2 + ____ O2 d. ____ NaOH e. ____ K + ____ Cl2 ____ H2 ____ H2O ____ HOH + ____ HCl + ____ Cl2 + ____ NaCl + ____ NaCl ____ KCl 3. A single replacement reaction starts with a compound and an element and ends up with a “new” or different compound and “new” or different element as the products. The uncombined element takes the place of the combined element in the compound. Which of the following reactions are single replacement reactions? Circle the letter and balance the circled reaction. ____ Na a. ____ NaCl b. ____ NaOH c. ____ K + ____ Cl2 ____ HOH + ____ HCl + ____ AgCl d. ____ Ca + ____ S e. ____ Na + ____ HCl ____ Ag + ____ NaCl + ____ KCl ____ CaS ____ H2 + ____ NaCl 4. A double replacement reaction starts with two compounds and ends with two “new” or different compounds as the products. The elements that make up each of the two compounds simple change partners to produce the two new compounds. Which of the following reactants are double replacement reactions? Circle the letter and balance the circled reaction. ____ Na a. ____ NaCl b. ____ Na2CO3 c. ____ Na e. ____ Ca + ____ CaCl2 + ____ HCl d. ____ AgNO3 + ____ Cl2 ____ H2 + ____ ZnCl2 + ____ S ____ CaCO3 + ____ NaCl ____ AgCl ____ CaS + ____ NaCl + ____ Zn(NO3) 2 Identifying and Balancing Chemical Equations Identify each of the following equations below as synthesis (S), decomposition (D), single replacement (SR), double replacement (DR), neutralization (N), or combustion (C). Type Balance _____ 1. ____ HgO ____ Hg _____ 2. ____ NaCl + ____ AgNO3 + ____ O2 ____ MgCl2 _____ 3. ____ Mg + ____ HCl _____ 4. ____ Zn + ____ H2SO4 _____ 5. ____ NaOH + ____ O2 _____ 8. ____ Cl2 + ____ NaBr _____ 9. ____ Zn + ____ CuSO4 _____ 13. ____ Na2O _____ 15. ____ HgO ____ Fe2O3 ____ Ca(NO3)2 ____ HgCl + ____ (NH4)2S + ____ O2 ____ CO2 _____ 19. ____ Al2O3 ____ Al + ____ O2 _____ 20. ____ CuCl2 + ____ H2S _____ 21. ____ KOH + ____ H3PO4 _____ 25. ____ NH4NO3 + ____ (NH4)2SO4 + ____ H2O ____ CuS + ____ HCl ____ H2O + ____ K3PO4 + ____ H2SO4 ____ MgSO4 + ____ O2 + ____ F2 + ____ H2O + ____ O2 ____ FeS _____ 18. ____ C2H6 _____ 24. ____ S8 + ____ H2 ____ NaBr + ____ Br2 _____ 23. ____ C4H10 + ____ Cu ____ NH3 + ____ Cl2 _____ 22. ____ Mg(OH)2 + ____ Br2 ____ Na2CO3 + ____ CO2 _____ 17. ____ FeSO4 + ____ CaSO4 + ____ O2 + ____ HNO3 + ____ N2 ____ Al(OH)3 ____ ZnSO4 ____ KCl _____ 12. ____ Ca(OH)2 _____ 16. ____ Na + ____ H2O ____ NaCl + ____ Fe _____ 14. ____ H2 ____ NaCl ____ H2O _____ 7. ____ H2 _____ 11. ____ H2O + ____ H2 + ____ H2 + ____ Ca(OH)2 _____ 10. ____ KClO3 + ____ AgCl ____ ZnSO4 + ____ HCl _____ 6. ____ Al2(SO4)3 ____ NaNO3 ____ CO2 + ____ H2O ____ SF6 ____N2O + ____ H2O + ____ H2O
