Find δs o for the combustion of methane to carbon dioxide and liquid water.

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:

$\mathbf{CH_{4(g)} + 2O_{2(g)} \to CO_{2(g)} + 2H_2O_{(l)}}$

The standard entropy of the combustion is expressed as:

$\mathbf{\Delta S^0 =(S^0 _{CO_{2}} + 2 \times S^0 _{H_{2}O} )+(-S^0 _{CH_{4}} -2 \times S^0 _{O_{2}} })$

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

$\mathbf{\Delta S^0 =(213.8 \8 \ J/mol.K + 2 \times69.92 \ J/mol.K )+(-186.16 \ J/mol.K -2 \times 205.04 \ J/mol.K})$

$\mathbf{\Delta S^0 =-242.6 \ J/mol.K}$

In July 2019, there were 1.5 million people who were marginally attached to the labor force, essentially unchanged from a year e

topjm [15]

These people are referred to as the <u>discouraged workers.</u>A person who is eligible for employment and can work but is unemployed currently and has not attempted to find employment in the last four weeks

Explanation:

Discouraged workers are the individuals who is eligible for employment and can work but is unemployed currently and had not made any attempt to find employment in the last four weeks.

For example: Young graduates,senior citizens.

Discouraged workers are not considered as a part of the labour force and are not counted in most official unemployment rates.

<u>These are people who were not in the labor force, although they wanted work and were available for it and had looked for jobs at some point in the previous 12 months. They were not counted as unemployed because they had not actively searched for work in the 4 weeks preceding the survey.</u>

If unemployed workers become discouraged, the measured unemployment rate will fall

Answer:

x-axis: Amount of candy sold

y- axis: Amount of money made

Billy is making $0.20 per candy bar.

Linear function: y=3/5x-6

Billy sold 50 candy bars if he made $24.

The x-intercept represents the point when he will earn a profit because at point (5,-3) he sold 5 candy bars but he still made a loss of $3.
