To determine

The correct option for the statement “Is the following chemical equation balanced? ${\text{2C}}_4{\text{H}}_{10}\left(\text{g}\right){\text{+13O}}_2\left(\text{g}\right)\to {\text{8CO}}_2\left(\text{g}\right)+{\text{10H}}_2\text{O}\left(\text{l}\right)$ ”.

Answer to Problem 3RAT

The correct option for the statement “Is the following chemical equation balanced? ${\text{2C}}_4{\text{H}}_{10}\left(\text{g}\right){\text{+13O}}_2\left(\text{g}\right)\to {\text{8CO}}_2\left(\text{g}\right)+{\text{10H}}_2\text{O}\left(\text{l}\right)$ ” is option (a).

Explanation of Solution

Any reaction containing identical number of reacting atoms as well as produced atoms is referred as balanced equation.

In any reaction, coefficients either describe the moles or the molecules of any participating species in any chemical equation.

In a given chemical equation,

${\text{2C}}_4{\text{H}}_{10}\left(\text{g}\right){\text{+13O}}_2\left(\text{g}\right)\to {\text{8CO}}_2\left(\text{g}\right)+{\text{10H}}_2\text{O}\left(\text{l}\right)$ ,

There are eight carbon atoms in the reactant side and eight carbon atoms on the product side, so the carbon atoms are balanced in the above equation.

There are twenty hydrogen atoms in the reactant side and twenty hydrogen atoms on the product side, so the hydrogen atoms are balanced in the above equation.

There are twenty-six oxygen atoms in the reactant side and twenty-six oxygen atoms on the product side, so the oxygen atoms are balanced in the above equation.

Thus, the reaction is balanced.

Conclusion:

Therefore, the correct option is option (a).
