select the correct compound.\nreactants undergo chemical reaction to form products. this chemical equation represents one such reaction. the coefficient for one of the reactants or products is incorrect. which part of the chemical equation is incorrect?\n2c₄h₁₀ + 10o₂ → 8co₂ + 10h₂o\nreset next
Answer
Explanation:
Step1: Balance carbon atoms
For the reaction of butane ($C_4H_{10}$) combustion, the number of carbon - atoms in reactants and products should be equal. In $2C_4H_{10}$, there are $2\times4 = 8$ carbon atoms, and in $8CO_2$ there are also 8 carbon atoms.
Step2: Balance hydrogen atoms
In $2C_4H_{10}$, there are $2\times10=20$ hydrogen atoms. In $10H_2O$, there are $10\times2 = 20$ hydrogen atoms.
Step3: Balance oxygen atoms
In $10O_2$, there are $10\times2=20$ oxygen atoms. In $8CO_2 + 10H_2O$, the number of oxygen atoms is $8\times2+10\times1=16 + 10=26$ oxygen atoms. The correct coefficient for $O_2$ should be 13 to balance the oxygen atoms. So the incorrect part is $10O_2$.
Answer:
$10O_2$
