Answer:

Gibbs Free Energy (ΔG)

Explanation:

Gibbs Free Energy (G) - Is the  energy associated with a chemical reaction that can be used to do useful work.  The free energy of a system is the sum of its enthalpy (H) minus the product of the temperature (Kelvin) and the entropy (S) of the system:

G = H -TS--------------------------------------------------------- (1)

ΔG = ΔH - TΔS----------------------------------------------(2)

ΔG = Negative, means the reaction is spontaneous

ΔG  = Positive, means the reaction is slow

ΔG  = Zero, means the reaction is in equilibrium

Give the empirical formula for C↓8H↓8
mr_godi [17]

Answer:

Empirical formula of  C₈H₈ =  CH

Explanation:

Data Given:

Molecular Formula = C₈H₈

Empirical Formula = ?

Solution

Empirical Formula:

Empirical formula is the simplest ration of atoms in the molecule but not all numbers of atoms in a compound.

So,

tha ration of the molecular formula should be divided by whole number to get the simplest ratio of molecule

        C₈H₈ Consist of  Carbon (C), and Hydrogen (H)

Now

Look at the ratio of these two atoms in the compound

                         C : H

                         8 : 8

Divide the ratio by two to get simplest ratio

                          C : H

                       8/8 : 8/8

                         1   :  1

So for the empirical formula is the simplest ratio of carbon to hydrogen 1 : 1

So the empirical formula will be

                     Empirical formula of  C₈H₈ =  CH
