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

There are three atoms in total! Hope this can help you out!
Answer:
There are 13 numbers in an aluminum atom and 13 electrons.
Explanation:
This is because the atomic number equals the number of protons and the atomic number of Al is 13. The number of electrons also equals the number of protons.
Answer: Positive, positive
Explanation:
Entropy is the measure of randomness or disorder of a system. If a system moves from an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.
is positive when randomness increases and is negative when randomness decreases.
Exothermic reactions are defined as the reactions in which energy is released in the form of heat and 
for the reaction comes out to be negative.
Endothermic reactions are defined as the reactions in which energy is absorbed in the form of heat and for the reaction comes out to be positive.
For a cold pack, the energy has to be absorbed for the dissolution of ammonium nitrate in water so that the surroundings feel cold.Thus as energy is absorbed, for the reaction comes out to be positive.
The solid form of ammonium nitrate is getting converted to ions and thus entropy increases and thus for the reaction comes out to be positive.
