A) how much co is required for the production of fe from 1000 tonnes of magnetite (fe2o4). assume that the iron ore is 100% pure.

b) how many kilograms of iron should be produced?

c) if the reaction yielded 555 kg of fe, what is the percentage yield for the process

Astable electron arrangement for an atom is one that does not easily change. how is this arrangement arrived at? a. valence electrons are transferred or shared to create a full outer shell of electrons. b. valence electrons are discarded into space to create a full outer shell of electrons. c. protons (positive charge) pair with valence electrons (negative charge) to create a strong bond. d. outer shells with valence electrons are transferred or shared.
