leslie incorrectly balances an equation as 2c₄h₁₀ + 12o₂ → 8co₂ + 10h₂o. which coefficient should she change? o 2 o 8 o 10 o 12
Answer
Explanation:
Step1: Count oxygen atoms on left - hand side
For $2C_4H_{10}+12O_2$, the number of oxygen atoms from $O_2$ is $12\times2 = 24$.
Step2: Count oxygen atoms on right - hand side
For $8CO_2 + 10H_2O$, the number of oxygen atoms from $CO_2$ is $8\times2=16$ and from $H_2O$ is $10\times1 = 10$. So total oxygen atoms on right - hand side is $16 + 10=26$.
Step3: Determine the coefficient to change
To balance the oxygen atoms, we need to change the coefficient of $O_2$.

12
