A major component of gasoline is octane (C8H18). When liquid octane is burned in the air it reacts with oxygen gas to produce ca

rbon dioxide gas and water vapor.
Calculate the moles of carbon dioxide produced by the reaction of 0.085 mol of oxygen. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

Answer:

0.027 moles of carbon dioxide produced by the reaction of 0.085 mol of oxygen.

Explanation:

2C_8H_{18}+50O_2\rightarrow 16CO_2+18H_2O

Moles of oxygen gas = 0.085 mol

According to reaction, 50 moles of oxygen gives 16 moles of carbon dioxide gas, then 0.085 moles of oxygen gas will give:

\frac{16}{50}\times 0.085 mol=0.0272 mol\approx 0.027 mol of carbon dioxide

0.027 moles of carbon dioxide produced by the reaction of 0.085 mol of oxygen.

Use the Clausius-Clapeyron equation... 

<span>Let T1 be the normal boiling point, which will occur at standard pressure (P1), which is 101.3 kPa (aka 760 torr or 1.00 atm). You know the vapour pressure (P2) at a different temperature (T2). And you are given the enthalpy of vaporization. Therefore, we can use the Clausius-Clapeyron equation.

</span>ln(P_1/P_2) = \frac{-\delta H_{vap}}{R}  \times [\frac{1}{T_1} - \frac{1}{T_2}]<span>

</span><span>ln(101.3 kPa / 52.7 kPa) = (-29.82 kJ/mol / 8.314x10^{-3} kJ/molK) (1/T - 1/329 K) 
</span>
------ some algebra goes here ----- 

<span>T = 349.99K ...... or ...... 76.8C </span>

Many electrical power plants use fossil fuels, a non-renewable resource to produce electricity?
Alisiya [41]

Answer:

Explanation:

Thermal Power Plants generate electricity by converting heat into electricity, essentially by burning a fuel. ... A coal power plant works in much the same way, but instead of a nuclear reactor heating water to make steam, the heat from the burning coal powers a steam turbine

Explain how movements along faults generate earthquakes<br><br><br>​
Scrat [10]

Explanation:

When a plate moves it shifts the earth, and it can cause an earthquake.

A fault is where two of earth's tectonic plates come together. They can slide against the other, causing earthquakes, they can push against each other causing mountains to form, and they can move apart from each other, causing  valleys or trenches.
