"1. A mineral can be formed through evaporating salt water which is when salt water evaporates.

you can do this at home with a bottle and mix salt and water together and see what happens when it dries up.

Examples: Gypsum and Halite

2. A mineral can also be formed through hot water solutions which is when ground water works its way down and is boiled by ground magma.

Examples are Gold, copper sulfur pyrite and galena."

Find δs o for the combustion of methane to carbon dioxide and liquid water.
mote1985 [20]

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}

<h3>The elements of a plot.</h3>

In English literature, there are five (5) main elements of a plot and these include the following;

  • Introduction (Exposition).
  • Rising action.
  • Climax.
  • Falling action.
  • Resolution

In English literature, the climax marks the turning point of events in a play or story and it is mostly attained when the character (protagonist) takes the last step to resolve a conflict.

That's what university is frequently mentioned on the web include Harvard University Yale University Stanford University and others you can get into that kind of college or universities but what is the difference between University and College according the college ranked college vs University in contrast and institution that offers both undergraduate and graduate degrees is considered a university they offer undergraduate programs that will lead a student towards a master's degree or a doctorate yeah so that's basically what it is when you actually think about these college stop everybody's asking about College college College college in college and I have no answer about the college College college well I don't want to talk about College college College college and college because well yeah that's what it is but the college is just a place that you are wanted to learn and scraped job to like get to a job but I'm not peeking from those four pieces and thank you just thank me down below thank thank thank me down below and then I'll think I look too and thank you this is basically a really really long as I say I do not care about it but just I hope you read it I don't think you will understand it but thank me down below I will thank you back thank you.
