Predict the products (Correct formulas!!) and balance the following reactions.<br />
Combination reactions: Make the binary ionic compound from the elements. (p.212-214)<br />
Example: For K + O2 ––––> answer is 4 K + O2 ––––> 2 K2O (K + O –2 )<br />
22. Al + Br2 -----> 23. Na + O2 ----><br />
Decomposition reactions: Decompose into elements when electricity is added. (p. 214 -216)<br />
Example: NaF –––> answer is 2 NaF –––> 2 Na + F2 (F2 is diatomic)<br />
electricity<br />
elect.<br />
24. HF --------------> 25. MgO ---––-><br />
Complete combustion of a hydrocarbon: O2 gas is a reactant, Products are CO2, H2O<br />
Ex: Complete Combustion of C6H6: Answer: 2 C6H6 + 15 O2 –––> 12 CO2 + 6 H2O (220-222)<br />
26. Complete combustion of C8H18<br />
27. Complete combustion of CH3OH<br />
Incomplete combustion of a hydrocarbon: O2 gas is a reactant, Products are CO, H2O<br />
Ex: Incomplete Combustion of C6H6: Ans: 2 C6H6 + 9 O2 –––> 12 CO + 6 H2O<br />
28. Incomplete combustion of C4H10
