after reading the passage, describe whether another reaction in the human body, the decomposition of hydrogen peroxide, is balanced. the equation for the decomposition of hydrogen peroxide is 2h2o2→ 2h2o + o2. support your answer with evidence from the chemical equation.
Answer
Answer:
The decomposition of hydrogen peroxide ($2H_2O_2\rightarrow 2H_2O + O_2$) is balanced.
Explanation:
Step1: Count hydrogen atoms on reactant side
On the left - hand side, for $2H_2O_2$, the number of hydrogen atoms is $2\times2 = 4$.
Step2: Count hydrogen atoms on product side
On the right - hand side, for $2H_2O$, the number of hydrogen atoms is $2\times2=4$.
Step3: Count oxygen atoms on reactant side
On the left - hand side, for $2H_2O_2$, the number of oxygen atoms is $2\times2 = 4$.
Step4: Count oxygen atoms on product side
On the right - hand side, in $2H_2O$ there are $2$ oxygen atoms and in $O_2$ there are $2$ oxygen atoms, so in total $2 + 2=4$ oxygen atoms. Since the number of hydrogen and oxygen atoms is the same on both sides of the equation, the reaction is balanced.
