Solving 7 Chemical Equations

This content was STOLEN from BrainMass.com - View the original, and get the already-completed solution here!

I desprately need help solving these chemical equations to help me to study for an exam.

Rules for Solving Chemical Equations:
1. Write the chemical reaction in word form
2. Post your symbols
3. Post diatomics (for single units only)
4. Post oxidation numbers for compounds
5. Post subscription (for compounds only)
6. Balance the chemical reactions using coeficients
7. Name the type of chemical reaction

Chemical Equations Problems:
1) Al+02---->Al2 O3
2) Hg O----> Hg+O2
3) NaOH+H2SO4---->Na2SO4+H2O
4) Fe+O2--->Fe2 O3
5) Pb (NO3)2+K2CrO4--->PbCrO4+KNO3
6) H2+N2--->NH3
7) C5 H5(NO3)3--->CO2+N2+H2O+O2
8) Fe+CuCl2--->Fe Cl2+Cu
9) KClO3--->KCl+O2
10) Mg+HCl--->H2+MgCl2

Solution Preview

We'll do these step by step. Follow the steps. They should be perfectly explanatory.

1) Al+O2---->Al2O3
2 Al+O2---->Al2O3
2 Al + 3/2 O2---->Al2O3
4 Al + 3 O2---->2 Al2O3
This is a synthesis reaction.

2) Hg O----> Hg+O2
2 HgO----> 2 Hg+O2
This is a decomposition reaction.

3) NaOH+H2SO4---->Na2SO4+H2O
2 ...

Solving Enthalpy Changes for Chemical Reactions

Calculate the enthalpy change for the following reactions
P4O6 + 2O2 ? P4O10
given the following enthalpies of reaction.

P4 + 3O2 ? P4O6 ?H = -1640.1 kJ equation 1
P4 + 5O2 ? P4O10 ?H = -2940.1 kJ equation 2

b) NO2(g) + (7/2) H2(g) ---> 2H2O(l) + NH3(g)

2NH3(g) ---> N2(g) + 3H2(g) ?H° = +92 kJ equation 1
(1/2) N2(g) + 2H2O(l) ---> NO2(g) + 2H2(g) ?H° = +170 kJ equation 2
