Answer:
The answer to your question is Ba(OH)₂ + 2HClO₄ ⇒ Ba(ClO₄)₂ + 2H₂O
Explanation:
Reactants
Barium hydroxide
Perchloric acid
Formula
Barium hydroxide = Ba(OH)₂
Perchloric acid = HClO₄
Equation (it is a double replacement)
Ba(OH)₂ + HClO₄ ⇒ Ba(ClO₄)₂ + H₂O
Reactants Elements Products
1 Ba 1
1 Cl 2
3 H 2
6 O 9
This reaction is unbalanced
2) Balance the chemical reaction
Ba(OH)₂ + 2HClO₄ ⇒ Ba(ClO₄)₂ + 2H₂O
Reactants Elements Products
1 Ba 1
2 Cl 2
4 H 4
10 O 10
Now the reaction is balanced
Products
Ba(ClO₄)₂ Barium perchloride
2H₂O water
<span>Four orbitals are needed to contain six electrons if two electrons are unpaired. According to Hund's rule, degenerate orbitals are filled evenly. Electrons minimize the force of repulsion by orbiting at a distance.</span>
