Question

When barium hydroxide reacts with sulfuric acid, barium sulfate and water are produced. The balanced equation for this reaction is: Ba(OH)2 (aq) H2SO4 (aq) BaSO4 (s) 2H2O (l)

Answer 1

Answer: The balanced equation for given reaction is
`Ba(OH)_(2)(aq) + H_(2)SO_(4)(aq) \rightarrow BaSO_(4)(s) + 2H_(2)O(l)`.

Step-by-step explanation:

A chemical equation which contains same number of atoms on both reactant and product side is called a balanced chemical equation.

For example,
`Ba(OH)_(2)(aq) + H_(2)SO_(4)(aq) \rightarrow BaSO_(4)(s) + 2H_(2)O(l)`

Number of atoms on reactant side are as follows.

• Ba = 1
• O = 6
• H = 4
• S = 1

Number of atoms on product side are as follows.

• Ba = 1
• O = 6
• H = 4
• S = 1

Since atoms on both reactant and product side are equal. Therefore, this equation is balanced.

Thus, we can conclude that balanced equation for given reaction is
`Ba(OH)_(2)(aq) + H_(2)SO_(4)(aq) \rightarrow BaSO_(4)(s) + 2H_(2)O(l)`.
