You need to find the arrow key on your computer and use it. --> or ==> or >>>>.
Using the coefficients in the balanced equation, convert mols each to mols Fe(OH)2.
3.70 mols Fe x (1 mol Fe(OH)2/1 mol Fe) = 3.70 mols Fe.
6.95 mol NiO(OH)2 x (1 mol Fe(OH)2/2 mol NiO(OH)2) = 3.475.
You get two different values which mans one of them is not right. In limiting reagent problems the smaller number ALWAYS wins.
In 1901, Thomas Edison invented the nickel-iron battery. The follwing reaction takes place in the battery.
Fe(s) + 2 NiO(OH)(s) + 2 H2O(l) Fe(OH)2(s) + 2 Ni(OH)2(aq)
How many mole of Fe(OH)2, is produced when 3.70 mol Fe and 6.95 mol NiO(OH) react?
