Calculate the ΔH for the following reaction: (15 pts) 3 Fe2O3+ Co → 2Fe304 + CO2
Given the following information:
Fe2O3 + 3 CO → 2 Fe 3 CO2
ΔH = -5.7KJ
Fe3O4 + CO → 3FeO + CO2
ΔH = -4.5KJ
Fe + CO2 → FeO + CO
ΔH = -0.3KJ

Particle exchange energy though elastic collision , hope this .

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
