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:

Its the second one i think. It isn't calculating any actual number, it is giving a sort of broad answer of everyone that needs it new or replaced
The combination that could be the total sales would be 360 tablets and 180 computers.
<h3>Total sales</h3>
Over 300 total sales were made in January
100 tablets and 20 computers were sold in February.
This means that total sales would be: (300+) 100 + 20 = 420+
Only options B and C have 420+ total sales.
But, there are more tablet sales than computers.
Thus, we are left with only option B
