Answer 2

Chemical Equations and Reaction Types

a) The balanced chemical equation for the reaction CO + O2 = CO2 is: 2CO + O2 = 2CO2. This is a combination reaction.

b) The balanced chemical equation for the reaction Fe3O4 + CO = Fe + CO2 is: Fe3O4 + 4CO = 3Fe + 4CO2. This is a single displacement reaction.

v) The balanced chemical equation for the reaction KClO3 = KCl + O2 is: 2KClO3 = 2KCl + 3O2. This is a decomposition reaction.

g) The balanced chemical equation for the reaction Al2O3 + H2SO4 = Al2(SO4)3 + H2O is: Al2O3 + 3H2SO4 = Al2(SO4)3 + 3H2O. This is a double displacement reaction.
