Question

Is this equation completely balanced? 2C8H8 + 25O2 8CO2 + 18H2O

A.No, because the number of carbon, hydrogen & oxygen atoms on both sides of the equation are not equal.
B.No, because the number of oxygen atoms on both sides of the equation are not equal.
C.Yes, because all of the coefficients are in their lowest whole number ratio.
D.No, because the number of hydrogen atoms on both sides of the equation are not equal.
E.Yes, because the number of products is equal to the number of reactants.

Answer 1

A.No, because the number of carbon, hydrogen & oxygen atoms on both sides of the equation are not equal

Answer 2

Answer: Option (A) is the correct answer.

Step-by-step explanation:

For an equation to be completely balanced, there should be equal number of reactants and products.

In the given equation.

`2C_(8)H_(8) + 25O_(2)\rightarrow 8CO_(2) + 18H_(2)O`

Number of carbon atoms on reactant side = 16

Number of hydrogen atoms on reactant side = 16

Number of oxygen atoms on reactant side = 50

Number of carbon atoms on product side = 8

Number of hydrogen atoms on product side = 36

Number of oxygen atoms on product side = 34

Hence, we can conclude that total number of reactants does not equal total number of products therefore, this equation is not completely balanced.
