Answer:
-605,5 kJ/mol of energy
Explanation:
Combustion of CH₄, CO and H₂ are:
CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(l) ΔH = -890 kJ/mol
CO(g) + ¹/₂O₂(g) → CO₂(g) ΔH = -283 kJ/mol
H₂(g) + ¹/₂O₂(g) → H₂O(l) ΔH = -286 kJ/mol
The heat combustion of methane gives <em>-890 kJ/mol </em>of energy. The water gas gives the average of energy between the reactions, that is:
-283kJ/mol -286kJ/mol /2 = <em>-284,5 kJ/mol of energy</em>
<em />
Difference between the two values is:
-890kJ/mol - (-284,5kJ/mol) = <em>-605,5 kJ/mol of energy</em>

Answer:
Isotopes
Explanation:
Isotopes are different forms of an element that have different mass numbers due to different number of neutrons but have the same atomic number(protons and electrons)
