25. sulfuric acid is a component of acid rain formed when gaseous sulfur dioxide pollutant reacts with gaseous oxygen and liquid water to form aqueous sulfuric acid. write a balanced chemical equation for this reaction.
Answer
Explanation:
Step1: Identify reactants and products
Reactants are $SO_2(g)$, $O_2(g)$, $H_2O(l)$; product is $H_2SO_4(aq)$.
Step2: Write un - balanced equation
$SO_2(g)+O_2(g)+H_2O(l)\rightarrow H_2SO_4(aq)$
Step3: Balance the equation
First, balance the sulfur atoms (already 1 on each side). Then, balance the oxygen and hydrogen atoms. Multiply $SO_2$ by 2, and we get $2SO_2(g)+O_2(g)+2H_2O(l)=2H_2SO_4(aq)$.
Answer:
$2SO_2(g)+O_2(g)+2H_2O(l)=2H_2SO_4(aq)$
