Answer:
Explanation:Having the same numbers of electrons or the same electronic structure.
1st balance C : C5H12 -> 5CO2
2nd balance H: C5H12 -> 6H2O
final balance O : (5x2+6)/2=8 -> 8O2
So answer is: C5H12+ 8O2 -> 5CO2+ 6H2O
Hola!
[ refer the attachment. ]
Compare this diagram with that of yours.. :)
hope it helps!
Answer:
uh?
Explanation:
if you know about them, you will know which one did what to the crime scene. and you can use some chemicals to preserve evidence.
A. N₂ (g) + 3 H₂ (g) --> 2 NH₃ (g)
B. The value for standard enthalpy of formation is empirical given that the reactants involved were pure elements. So, you can search this on the internet or in any textbook. The Hf for NH₃ is -46.0 kJ/mol.
C. C (s) + O₂ (g) --> CO₂ (g)
D. The Hf for CO₂ is <span>-393.5 kJ/mol
E. 4 Fe (s) + 3 O</span>₂ (g) --> 2 Fe₂O₃ (s)
F. The Hf for solid Fe₂O₃ is -826.0 kJ/mol.
G. C (s) + 2 H₂ (g) --> CH₄ (g)
H. The Hf for methane gas is -74.9 kJ/mol.
