Question

ASSERTION: The following chemical equation,

2C6H6+7/2O2 = 4CO2 + 3H2O

Is balanced chemical equation.

REASON: In a balance chemical equation, the total number of atoms of each element is equal on both side of the equation.

​

Answer 1

Answer:

The assertion is wrong.But the reason is correct

Explanation:

Because in assertion they are given the combustion of benzene and given equation is not balanced one.

The balanced equation is 2C6H6+15O2--->12CO2+6H2O.

Answer 2

Answer:

For the give REASON: In a balance chem ical equation, the total number of atoms of each element is equal on both side of the equa tion.

The assertion is correct and the reason is also correct and explains why the equation is balanced.

Explanation:

The chemical equation, 2C6H6 + 7/2O2 = 4CO2 + 3H2O, represents the combustion of benzene in the pres ence of oxygen to produce carbon dioxide and water. To ch eck if this equation is balanced, we need to count the number of atoms of each element on both sides of the equation.

On the left-hand side of the equation, we have 2 molecules of benzene (C6H6) and 7/2 molecules of oxygen (O2). This gives us a total of 12 carbon atoms, 12 hydrogen atoms, and 7 oxygen atoms.

On the right-hand side of the equation, we have 4 molecules of carbon dioxide (CO2) and 3 molecules of wa ter (H2O). This gives us a total of 12 carbon atoms, 12 hydrogen atoms, and 10 oxygen atoms.

Since the number of atoms of each element is the same on both sides of the equation, the equation is balanced. Therefore, the assertion is true, and the reason is also true and correctly explains why the equation is balanced.
