Chemistry! #2

The next thing I want to post for the chemistry part of my portfolio is questions out of the text book. These questions come from page 265 and are skeleton equations that I had to A) classify the reaction B) finish the equation C) balance the equation. The parts of the equation that I underline will be the part that was in the textbook. --- N

Fe2O3 ----> Fe + O2   (Decomposition)
Al + NiBr3 ---> AlBr3 + Ni (Single Replacement)
3Cl2 + 2NiBr2 ---> 2NiCl3 + 2Br2 (Single Replacement)
2HCl + Mg(OH)2 ---> 2H2O + MgCl2 (Neutralization)
2C18H38 + 37O2 ---> 38H2O + 36CO2 (Combustion)
6Li + N2 ---> 2Li3N (Synthesis)
AgNO3 + Na2CrO4 ---> AgCrO4 + Na2NO3 (Double Replacement)

I put this in because it shows not only that I know the six different types of reactions, but I also know how to balance equations.
