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.
Signs that a chemical reaction is occurring are: 1. change in color 2. change in odor 3. change in pH, as in changes from acid to base or base to acid
Answer:
Explanation:
Total pressure of the mixture = 300 mm Hg
equation of reaction
C₇ H₁₆(g) + 11 O₂ (g) → 7 CO₂(g) + 8 H₂O(g)
partial pressure of heptane = mole fraction heptane × total pressure = 1 / 12 × 300 mm Hg = 25 mm Hg
partial pressure of oxygen = mole fraction oxygen × total pressure = 11 / 12 × 300 mm Hg = 275 mm Hg
After the reaction
total number of mole before the reaction = 12
total number of mole after the reaction = 15
temperature and volume did not change
if 12 to 300 mm Hg
15 will be 15 × 300 / 12 = 375 mm Hg
partial pressure of water vapor = mole fraction of water vapor × 375 mm Hg = 8 / 15 × 375 mm Hg = 200 mm Hg
Cars up north require more antifreeze than water as a result of the colder
temperature which makes the coolant in vehicles more prone to freezing.
<h3>What is Freezing point depression?</h3>
This is a situation which occurs when solutes are added to a solvent in
order to reduce the freezing point of the solvent. The impurities help lower
the freezing point of the solvent and is commonly used in vehicles.
This is because cars in the North are exposed to colder temperatures
which could freeze the coolant(solvent).
