Line one: 4h atoms and 2o atoms on reactant and product side.
Line two: 4fe atoms 6o atoms on reactant and product side.
Line three: 2cl atoms, 2na atoms and 2br atoms on both the reactant and product side.
Answer:
They are all located in the same horizontal row or period.
Explanation:
In the periodic table the elements are arranged according to their increasing atomic number.The elements those contain low atomic number are placed in the first row such as hydrogen and helium. similarly the radioactive elements those have high atomic number are placed in 7th or 8th row.
All the elements of a family in the peroidic table have common features are located in same horizontal row or period.For example fluorine,chlorine,bromine and iodine are placed in VII B class of periodic table as all of them are electronegative in nature.
FeO + Al -> AlO + Fe
As you can see, this type of reaction would lead to be a Single Placement (or Replacement) reaction!

Answer:
AuCl
Explanation:
The solubility product constant, ksp, is defined as:
MₓYₙ(s) ⇄ xMⁿ⁺(aq) + nYˣ⁻(aq)
ksp = [Mⁿ⁺]ˣ + [Yˣ⁻]ⁿ
Thus, the higher ksp, the more soluble the compound is. Thus, the lower ksp the less soluble the compound is precipitating first. As the lower ksp is for Au, the first compound in precipitate is <em>AuCl</em>
