question

Chemical reactions can be classified as either heterogeneous or homogeneous. Which of the following equations below is best classified as a heterogeneous reaction?

category

chemistry

options

  1. 2C2H2(g) + 5O2(g) → 4CO2(g) + 2H2O(g)
  2. C2H2(g) + 5N2O(g) → CO2(g) + H2O(g) + 5N2(g)
  3. C2H5OH(aq) + O2(aq) → HC2H3O2(aq) + H2O(aq)
  4. C(s) + H2O(g) → H2(g) + CO(g)
  5. N2(g) + 3H2(g) → 2NH3(g)
  6. 2H2(g) + O2(g) → 2H2O(g)
  7. 2CO(g) + O2(g) → 2CO2(g)
  8. 2H2O2(aq) → 2H2O(l) + O2(g)
  9. CH4(g) + 2O2(g) → CO2(g) + 2H2O(g)
