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:

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

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

School taxes for a local district are 2. 5% of a household's income. The smith household earns $80,000 per year. How much do the

Mashutka [201]

Answer:

2.5% of $80,000=$2,000

The Smiths pay $2,000 in school taxes per year.

Explanation:

100%=$80,000

10%=$80,000(100%)/10=$8,000(10%)

5%=$8,000(10%)/2=$4,000(5%)

2.5%=$4,000(5%)/2=$2,000(2.5%)

Choose the correct word or phrase to complete the sentence. _____ mi parte, no hay problemas. por para

Natasha_Volkova [10]

The complete sentence will be:

<em>"Por mi parte, no hay problemas".</em>

<h3>How to complete the sentence?</h3>

Here we have the sentence:

___ mi parte, no hay problemas.

This would be translated to:

____ my part, there are no problems.

In English, we can complete this as:

For my part, there are no problems.

Where "For" can be translated to "por" or "para" depending on the context. In this case, would be translated to "por" (Usually used like this when we talk about ourselves).

Then the complete sentence is:

Por mi parte, no hay problemas.
