Nitroglycerine ( C3H5N3O9) is a very strong explosive that degrades over time and is too shock sensitive to transport safely. Dynamite is made by combining nitroglycerine with stabilizers and adsorbents, which makes it much safer to use. The explosion of nitroglycerin can be represented by: 4C3H5N3O9(l)→6N2(g)+12CO(g)+10H2O(g)+7O2(g) A stick of 40% dynamite is about 20 cm long and about 3 cm in diameter and weighs 203 grams. It is 40.0% nitroglycerine by mass. What is the total number of moles of gas produced when a stick of 40% dynamite explodes?

A natural-gas storage tank is a cylinder with a moveable topwhose volume can change only as its height changes. Its radiusremains fixed. The height of the cylinder is 22.6 m on a day whenthe temperature is 22°C. The next day the height of the cylinderincreases to 23.8 m when the gas expands because of a heatwave. Find the temperature on the second day, assuming that thepressure and amount of gas in the storage tank have not changed.

In a diesel engine the fuel is ignited when it is injected into hot compressed air, heated by the compression itself. In a typical high-speed diesel engine, the chamber in the cylinder has a diameter of 10.7 cm and a length of 13.4 cm. On compression, the length of the chamber is shortened by 12.7 cm (a "5-inch stroke"). The compression of the air changes its pressure from 1.00 to 32.0 atm. The temperature of the air before compression is 345 K. As a result of the compression, what will be the final air temperature (in Kand °C) just before the fuel injection? temperature - i K= i °C

A movie stunt performer is filming a scene where he swings across a river on a vine. The safety crew must use a vine with enough strength so that it doesn't break while swinging. The stunt performer's mass is 88.0 kg, the vine is 12.0 m long, and the speed of the stunt performer at the bottom of the swing has been determined to be 8.60 m/s. What is the minimum tension force (in N) the vine must be able to support without breaking? N Need Help? Submit Answer Read It

The term “airbag” itself is misleading since there’s no significant “air” in these cushions. They are, instead, shaped and vented nylon-fabric pillows that fill, when deployed, with nitrogen gas. They are designed to supplement seatbelt restraints and help distribute the load exerted on a human body during an accident to minimize the deceleration rate and likelihood of injury. But while “supplement the seatbelt” is the mission of airbags, federal regulations require that they be tested and made effective for unbelted occupants, vastly complicating their task. Airbags must do their work quickly because the window of opportunity—the time between a car’s collision with an object and an occupant’s impact on the steering wheel or instrument panel—lasts only milliseconds. For illustration’s sake, imagine a Corvette hitting a bridge abutment head-on at 30 mph. The clock starts the instant the tip of the car’s nose hits the concrete. The Mechanics There are six main parts of an airbag system:…

In a parallel universe the laws of physics and chemistry are quite different. A solid substance when passes to the gaseous state keeps it 3-D structure, its volume and only its kinetic energy increases. Suppose our ideal gas equation in this form; P.MA=dRT can be applied to these gases. Derive an equation for the pressure of a substance that has a body-centered cubic (BCC) structure that shows the relation between P and r. Take the side length of the cube as "a", atomic radius as "r", density as "d", molar mass as "MA", number of atoms as "n" and Avogadro number as "NA". Verify your derived equation by dimensional analysis.

1. Pressure drops with altitude, and in fact Denver has an atmospheric pressure of 83.3 kPa, compared with 101.3 kPa at sea level. To soft-cook an egg requires 5-6 minutes at sea level. Use your knowledge of atmospheric pressure to explain why it will take longer to soft-cook an egg in Denver. 2.The Salesforce Tower is the tallest building in San Francisco, at a height of 330 m; would you expect to see a difference in the boiling point of water between the ground and highest floors? Explain your answer.

Before small batteries were available, carbide lamps were used for bicycle lights. Acetylene gas, C2H2, and solid calcium hydroxide were formed by the reaction of calcium carbide, CaC2, with water. The ignition of the acetylene gas provided the light. Currently, the same lamps are used by some cavers, and calcium carbide is used to produce acetylene for carbide cannons.(a) Outline the steps necessary to answer the following question: What volume of C2H2 at 1.005 atm and 12.2 °C is formed by the reaction of 15.48 g of CaC2 with water?(b) Answer the question.

Pressure cookers have been around for more than 300 years, although their use has strongly declined in recent years (early models had a nasty habit of exploding). How much force must the latches holding the lid onto a pressure cooker be able to withstand if the circular lid is 25.0 cm in diameter and the gauge pressure inside is 300 atm? Neglect the weight of the lid.

Gases produced by a chemical reaction can easily be collected over water. To determine the pressure of the dry gas, the vapor pressure of the water at that temperature must be subtracted from the total pressure. 1) Consider the following reaction: Mg(s) +2 HC1(ag) → MgCl2(ag) + H2(9) The total pressure of gas collected over water is 695.0 mmHg and the temperature is 24.0°C What is the pressure of hydrogen gas formed in mmHg? Pressure = mmHg
