Answer:
3 Fe (s) + 4 H2O (l) -----> Fe3O4 (s) + 4 H2 (g)
Explanation:
your question is not completed , perhaps the question is similar to this solution, you can use it .
The balanced equation is
3 Fe (s) + 4 H2O (l) -----> Fe3O4 (s) + 4 H2 (g)
Explanation: In order to balance an equation we must ensure that the number of atoms of each species on right side of the arrow must be equal to the number of atoms of each species on left side of the arrow.
6.9 x 10 to the power of 3 if I am not mistaken.

are not very reactive with other elements.
Explanation:Noble gases:
are highly reactive.
react only with other gases.
do not appear in the periodic table.
are not very reactive with other elements.
Calculate the number of moles for each element. n=m/M Then compare, and which ever one is lowest is the limiting reactant because no more products can form without one or the other.
