Common Stand on Climate Change. We've got to reduce our dependence on foreign oil; it's a matter of homeland security. Fine. Nobody's arguing. But the solutions that get offered -- drilling in ANWR, mandating better automobile fuel efficiency, pushing ethanol -- don't really solve anything. They're politically impossible, or too expensive, or contrary to free-market forces. They're losers.
Energy-independence advocate Gal Luft looks for winners. The former lieutenant colonel in the Israel Defense Forces and counterterrorism expert fervently believes that the only way to make America safe is to make it energy independent. And so as executive director of the Institute for the Analysis of Global Security and cofounder of the Set America Free Coalition, he has set out to do just that.

Luft advises Congress and security companies. He briefs industrial and environmental groups. Yet what separates him from other energy specialists are his pragmatic solutions. He doesn't peddle pie-in-the-sky political strategies. He's a realist. He has a single goal: freeing America from the grip of foreign oil. And he wants to do it now. At right are four steps he says we can -- and should -- take today.

Problem Page Gaseous butane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Supposed 8.14 g

Gnoma [55]

Answer:

12.6 g

Explanation:

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

For butane:-

Mass of butane = 8.14 g

Molar mass of butane = 58.12 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{8.14\ g}{58.12\ g/mol}$

$Moles\ of\ butane= 0.14\ mol$

Given: For $O_2$

Given mass = 41 g

Molar mass of $O_2$ = 31.9988 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{41\ g}{31.9988\ g/mol}$

$Moles\ of\ O_2 = 1.28\ mol$

According to the given reaction:

$2C_4H_{10}+13O_2\rightarrow 8CO_2+10H_2O$

2 moles of butane react with 13 moles of oxygen

Also,

1 mole of butane react with 6.5 moles of oxygen

So,

0.14 mole of butane react with 6.5*0.14 moles of oxygen

Moles of oxygen = 0.91 moles

Available moles of $O_2$ = 1.28 moles (Extra)

Limiting reagent is the one which is present in small amount. Thus, butane is limiting reagent.

The formation of the product is governed by the limiting reagent. So,

2 moles of butane forms 10 moles of water

Also,

1 mole of butane forms 10 moles of water

So,

0.14 mole of butane forms 5*0.14 mole of water

Moles of water = 0.7 moles

Molar mass of water = 18 g/mol

So,

Mass of water= Moles × Molar mass = 0.7 × 18 g = 12.6 g
