Answer
Explanation:
Step1: Balance the water - decomposition equation
The un - balanced equation is $H_2O\rightarrow H_2 + O_2$. On the reactant side, we have 1 oxygen atom and 2 hydrogen atoms, and on the product side, 2 oxygen atoms and 2 hydrogen atoms. To balance the oxygen atoms, we put a 2 in front of $H_2O$ and a 2 in front of $H_2$. The balanced equation is $2H_2O\rightarrow 2H_2+O_2$. The coefficients are 2 for $H_2O$, 2 for $H_2$ and 1 for $O_2$.
Step2: Simplify the carbon - monoxide decomposition equation
The given equation is $4CO\rightarrow 2C + 2CO_2$. We can divide each coefficient by 2. The simplified balanced equation is $2CO\rightarrow C + CO_2$. The coefficients are 2 for $CO$, 1 for $C$ and 1 for $CO_2$.
Answer:
For $H_2O\rightarrow H_2 + O_2$, the coefficients are 2, 2, 1. For $4CO\rightarrow 2C + 2CO_2$, the simplified coefficients are 2, 1, 1.
