c) How many grams of eqFe(OH)_2/eq are needed be prepare 4 moles of eqFe(OH)_3/eq?

d) Write the names and physical states of each substance in this process.


One of the essential steps of stoichiometric calculation is mole comparison, without which one cannot get unknown moles và without these moles, mass also cannot be computed.

Answer và Explanation:1

The given reaction is shown below.

eqH_2O_(l) + Fe(OH)_2(s) + O_2(g) ightarrow Fe(OH)_3(s)/eq

Part a
