Problem: Balance the following equations and indicate the type of reactions(a) Fe(s) + S8(g) → FeS(s)(b) H2S(aq) + KOH(aq) → H2O(l) + K2S(aq)(c) NaCl(l) → Na(l) + Cl2(g)

FREE Expert Solution

We’re being asked to balance the given equations.

Recall that when balancing chemical equations, we have to make sure that the number of elements on both sides is equal with the lowest whole number coefficients.

Reaction 1:

Fe(s) + S8(g) → FeS(s)

Fe        1

S          8

Fe        1

S          1
