Homework Help: Chemistry

Posted by Derrick on Thursday, July 15, 2010 at 8:13pm.

This question is very confusing, I do not understand what it wants me to do.

Each reaction below has been identified by type. Use this information to help predict products. Copy and then complete each equation by writing the products of the reactions. Remember to include subscripts and parentheses when required.

This is what I did, not quite understanding what I was supposed to do.

A) Al + F2 --> Synthesis

Products: 1 atom of aluminum metal, 2 molecules of fluorine gas.

2Al + 3F2 --> 2AlF3

B) K+O2 --> Synthesis

Products: 1 atom of potassium metal, 2 molecules of oxygen gas.

4K + O2 --> 2K2O

C) C2H6+O2 --> Combustion

Products: hydrocarbon, oxygen

C2H6 + 4O2 --> 2CO2 + 3H2O

D) C6H12O4 + O2--> Combustion

Products: Carbon, hydrogen, Oxygen

C6H12O4 + 7O2 --> 6CO2 + 6H2O

Is this what I'm supposed to do, or am I totally off track?
