Solving 7 Chemical Equations
Not what you're looking for?
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
