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:

The SI V-Scope is indeed a virtual microscope program that can stimulate the use of a compound light microscope so this is <u>TRUE</u>.
<h3>What is a SI V-Scope?</h3>
The SI V-Scope stands for a Science Interactive and then Virtual scope which is used simulate the way that a compound light microscope works.
These microscopes are very useful because they help people who don't have a physical microscope to access microscopes wherever they are.

Answer:
2558 N.
Explanation:Each rope takes half, so the vertical component of the force on each rope is half of this, or 1960 N.. But they are pulling at a 40 degree angle, so if t is the tension then t*cos(40) = 1960. This gives t = 2558 N.
