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
