The entropy change ΔS for the combustion of methane to carbon dioxide and liquid water is -242.6 J/mol.K
<h3>What is the Entropy in a Chemical system?</h3>
In a chemical system, Entropy (ΔS) is a quantitative measure of the variety of possible ways to disperse energy inside a chemical system.
- In an isothermal process, entropy is determined as the quantity of heat transmitted to a system.
The chemical reaction for the combustion of methane can be expressed as:

The standard entropy of the combustion is expressed as:

Replacing the standard entropies of the compounds into the above equation, we have:

Answer:
Explanation:
the equation you use here is m=fa or mass=force x acceleration
you plug in the 13.5 N as the force, 6.5 m/s^2 as the acceleration, and do the math.
13.5 x 6.5
That would equal 87.75 which would be your answer.
