Which is the correctly balanced equation for the reaction of rust, fe2o3, and hydrochloric acid, hcl? fe2o3 + hcl → fecl3 + h2o fe2o3 +3 hcl → 2 fecl3 + h2o fe2o3 + 6 hcl → 2 fecl3 + 3 h2o fe2o3 + 3 hcl → 2 fecl3 + 3 h2o

The correct answer is

Explanation:

Rust is the reddish-brown compound having formula (Ferric oxide) and when it reacts with acid, it forms a salt and releases water molecule.

The equation for the reaction of rust with hydrochloric acid follows:

By Stoichiometry of the reaction:

1 mole of ferric oxide reacts with 6 moles of hydrochloric acid to produce 2 moles of ferric chloride and 3 moles of water.
