Answer : The correct option is, (C) 0.675 M
Explanation :
Using neutralization law,
where,
= concentration of 
= 13.5 M
= concentration of diluted solution = ?
= volume of = 25.0 ml = 0.0250 L
conversion used : (1 L = 1000 mL)
= volume of diluted solution = 0.500 L
Now put all the given values in the above law, we get the concentration of the diluted solution.
Therefore, the concentration of the diluted solution is 0.675 M

FeS + H₂O → FeO + H₂S
Explanation:
Iron Sulfide = FeS
Water = H₂O
FeS + H₂O → FeO + H₂S
To balance this equation, we can use a mathematical method. This involves solving simple algebraic equations
aFeS + bH₂O → cFeO + dH₂S
a,b,c and d are the coefficients needed to balance up the equation:
Conserving Fe: a = c
S: a = d
H: 2b = 2d
O: b = c
let a = 1, c= 1, b = 1 d = 1
The balanced equation is: FeS + H₂O → FeO + H₂S
