Question

3 fill in the blank 1 point balance the reaction shown below by typing the correct coefficient. all boxes must be filled, so include coefficients of \1\ as necessary. type your answer... fe₂(so₄)₃ + type your answer... koh → type your answer... k₂so₄ + type your answer... fe(oh)₃

Explanation:

Step1: Balance Fe atoms

There are 2 Fe atoms in $Fe_2(SO_4)_3$. So, we need 2 moles of $Fe(OH)_2$.

Step2: Balance $SO_4^{2 -}$ ions

There are 3 $SO_4^{2 -}$ ions in $Fe_2(SO_4)_3$. So, we need 3 moles of $K_2SO_4$.

Step3: Balance K atoms

Since we have 3 moles of $K_2SO_4$, we need 6 moles of KOH to get 6 K atoms on the left - hand side. But if we consider the balanced Fe and $SO_4^{2 -}$ already, we find that the balanced equation is $Fe_2(SO_4)_3+2KOH = K_2SO_4 + 2Fe(OH)_2$. So the coefficients are 1, 2, 1, 2.

Answer:

1, 2, 1, 2
