<u>Answer:</u> The coefficients for balancing the given chemical equation are 2, 7, 4 and 6

<u>Explanation:</u>

Every balanced chemical equation follows law of conservation of mass.

This law states that mass can neither be created nor be destroyed, but it can only be transformed from one form to another form. This also means that total number of individual atoms on the reactant side must be equal to the total number of individual atoms on the product side.

The given balanced chemical equation follows:

2C_2H_6+7O_2\rightarrow 4CO_2+6H_2O

<u>On reactant side:</u>

Number of carbon atoms = 4

Number of hydrogen atoms = 12

Number of oxygen atoms = 14

<u>On product side:</u>

Number of carbon atoms = 4

Number of hydrogen atoms = 12

Number of oxygen atoms = 14

Hence, the coefficients for balancing the given chemical equation are 2, 7, 4 and 6

When balancing a chemical equation, the number of h atoms in 2 ch4 is eight?
Viktor [21]
Yes... that is correct.

CH4 is methane so the coefficent in front of it would double the number of atoms of each element

What is Keq for the reaction N₂ + 3H2 = 2NH3 if the equilibrium
hram777 [196]

The Keq for the reaction N₂ + 3H2 = 2NH3 if the equilibrium concentrations are Keq = 1.5. The correct option is D.

<h3>What is Keq?</h3>

Keq is the ratio of the concentration of reactant to the concentration of the product.

The balanced equation is

N₂ + 3H₂  = 2NH₃

The equilibrium constant is \rm \dfrac{[NH_3]^2}{[N_2]\; [H_2]^3}

The given concentrations of the compounds have been:

Ammonia = 3 M

Nitrogen = 1 M

Hydrogen = 2 M

\rm \dfrac{9}{1\times 8} = 1.5

Thus, the correct option is D. Keq = 1.5.
