I'm not sure if I balanced this equation correctly. Can someone please check it for me?
I need them to be correct so I can correctly do the other questions that follow. If incorrect, will you please provide me with the correct answer? Thanks.
1) CaCO3(s) > CaO(s)+CO2(g)
a) CaCO3+1206.9KJ > Ca+C+3/2 O2
b) Ca+1/2 O2 > CaO+635.1KJ
c) C+O2 > 393.5KJ+CO2
---------------------------------------
Net (Answer): CaCO3+2O2+178.3KJ > CaO+3/2 O2+CO2
2) Mg(OH)2 (s) > MgO(s)+H2O(L)
a) Mg(OH)2+924.5KJ > Mg+O2+H2
b) Mg+1/2 O2 > MgO+601.7KJ
c) H2+1/2 O2 > 285.8KJ+H2O
------------------------------------------------
Net (Answer): Mg(OH)2+37.0KJ > MgO+H2O
I also have no idea how to find the net for this equation (same steps as above):
NH3(g)+O2(g) > NO(g)+3/2 H2O(g)
Help is appreciated!
