|
Answer» 1. potassium CHLORIDE + silver nitrate --> potassium nitrate + silver chloride KCl + AgNO3 --> KNO3 + AgCl 2. aluminum hydroxide + sodium nitrate --> aluminum nitrate + sodium hydroxide Al(OH)3 + 3 NaNO3 --> Al(NO3)3 + 3 NaOH 3. iron metal + copper(II) SULFATE -->iron(II) sulfate + copper metal Fe + CuSO4 --> FESO4 + Cu 4. aluminum metal + copper(II) chloride --> aluminum chloride + copper metal 2 Al + 3 CuCl2 --> 2 AlCl3 + 3 Cu 5. potassium bromide --> potassium metal + bromine 2 KBr --> 2 K + Br2 6. calcium carbonate --> calcium oxide + carbon dioxide gas CaCO3 --> CaO + CO2 7. zinc metal + oxygen gas --> zinc oxide 2 Zn + O2 --> 2 ZnO 8. chlorine gas + sodium metal --> sodium chloride Cl2 + 2 Na --> 2 NaCl 9. aluminum sulfate + barium chloride --> aluminum chloride + barium sulfate Al2(SO4)3 + 3 BaCl2 --> 2 AlCl3 + 3 BaSO4 10. beryllium fluoride + magnesium --> magnesium fluoride + beryllium BeF2 + Mg --> MgF2 + Be 11. sodium hydrogen carbonate --> sodium carbonate + carbon dioxide + water 2 NaHCO3 --> Na2CO3 + CO2 + H2O Complete the word equation for the following chemical equations. Then below the word equation, write the balanced chemical equation. Indicate the type of reaction on the line to the left of the equation by classifying each reaction as single replacement (SR), double replacement (DR), decomposition (D), synthesis (S) (or combination), or combustion (C). _DR_ 12. aluminum sulfate + calcium phosphate --> aluminum phosphate + calcium sulfate, Al2(SO4)3 + Ca3(PO4)2 --> 2 AlPO4 + 3 CaSO4 _DR_ 13. magnesium chloride + silver nitrate --> magnesium nitrate + silver chloride, MgCl2 + 2 AgNO3 --> Mg(NO3)2 + 2 AgCl _D__ 14. sodium chlorate --> sodium chloride + oxygen, 2 NaClO3 --> 2 NaCl + 3 O2 _S__ 15. hydrogen gas + oxygen gas --> water, 2 H2 + O2 --> 2 H2O _SR_ 16. zinc metal + copper(II) nitrate --> zinc nitrate + copper Zn + Cu(NO3)2 --> Cu + Zn(NO3)2 _D__ 17. sulfurous acid, H2SO3 --> water + sulfur dioxide H2SO3 --> H2 + SO2 _DR_ 18. copper(II) oxide + sulfuric acid. copper (II) sulfate + water CuO + H2SO4 --> CuSO4 + H2O _S__ 19. nitrogen gas + hydrogen gas --> ammonia (NH3) 2 N2 + 3 H2 --> 2 NH3 _SR_ 20. sodium iodide + chlorine gas --> sodium chloride + iodine 2 NaI + Cl2 --> 2 NaCl + I2 _D__ 21. copper(II) hydroxide --> copper(II) oxide + water Cu(OH)2 --> CuO + H2O _S__ 22. ammonia gas (NH3) + hydrochloric acid (HCl) --> ammonium chloride NH3 + HCl --> NH4Cl _SR_ 23. potassium metal + water (hint: H+OH-) --> potassium hydroxide and hydrogen K + H+OH- --> 2 KOH + H2 _C__ 24. propane (C3H8) + oxygen --> carbon dioxide and water C3H8 + 5 O2 --> 3 CO2 + 4 H2O |
