Answer:

The correct answer is <em><u>A) At least once a year</u></em>

Explanation:

The battery and charging systems are very robust. However, they play such an important part that it is better to maintain and upkeep for maximum performance.

Once a year is an ideal time to check the charging and battery. If you have the time and expertise, you can obviously do it twice a year.

If you only do it once a year, it is better to do in the Fall, before winter arrives, so you are prepared.

you are moving across town. doing your research, you find that the average rate of a moving company is $250 per hour for a movin
iragen [17]

Based on the information given, the marginal cost of the price that should be paid is $250 per hour.

This is an incomplete information. From the complete information, the number of moving crew will be gotten where the marginal cost is equal to the marginal benefit and this will be at the 4th hour. Therefore, the <em>marginal cost</em> and benefit equal $250.

Therefore, one should hire movers for 4 hours. Therefore, based on the information given, the consumer surplus will be:

= $600 + $370 + $250

= $1220

In conclusion, the total consumer surplus for hiring a crew for<u> 4 hours</u> will be<u> $1220.</u>

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}
