Question

what type of reaction is this? 2Fe2O3 + 3C --> 3CO2 + 4Fe
single replacement
combination
decomposition

Answer 1

Redox reaction, cause Fe is reduced to elemental state, simultaneously C is oxidised to +4 oxidation state.

Answer 2

is it a single , combination or decomposition

Answer 3

not sure of that but I think it is a single reaction.

Answer 4

it's a single replacement. it is ALSO a redox reaction because the oxidation state changes, but so are all single replacements
