reacts with sodium bicarbonate to produce a gas. 2. Acetic acid and sodium bicarbonate are the chemical names for vinegar and baking soda‚ respectively. 3. The two main purposes of an air bag are to slow a person’s forward movement into the steering wheel (or dashboard) and to provide a cushion between the person and the steering wheel (or dashboard). 4. The three parts of an air bag are the bag itself‚ the sensors‚ and the inflation system (or gas generator). 5. The main chemical responsible

Ley de Boyle Ley de Boyle (designado a veces Ley de Boyle-Mariotte) es uno de leyes del gas y base de la derivación para ley ideal del gas‚ que describe la relación entre el producto presión y volumen dentro de a sistema cerrado como constante cuando sigue habiendo la temperatura y los topos en una medida fija; ambas entidades siguen siendo inverso proporcionales. Historia La ley de Boyle se nombra después del filósofo natural irlandés Roberto Boyle (Lismore‚ Condado Waterford‚ 1627-1691) quién

find the weight of the two together using a sensitive balance. • Pour 0.5 mL of the unknown volatile liquid into the test tube‚ insert the cork‚ and place the tube into boiling hot water while keeping the cork above water level. As the gas evaporates‚ excess gas will be released throughout the whole in the cork. Keep the test tube in the hot water for at least three minutes after all the liquid has vaporized and measure the temperature of the water. • Quickly cool the test tube in an ice bath

increase in volume the pressure in the synovial fluids drops forming bubbles. When the joint is stretched far enough the pressure drops so low that these bubbles burst‚ producing a popping sound. It takes half and half for the gas to dissolve back into the synovial fluids. Once gas is dissolved it is possible to pop knuckles again. Synovial fluid present in your joint acts as a lubricant. The fluid contains the gases oxygen‚ nitrogen and carbon dioxide. Habitual cracking just for the heck of it is

Catalyst by Laurie Halse Anderson‚ there are three main sections‚ Solid‚ Liquid‚ and Gas. The main character‚ Kate‚ is very interested in science and the three titles are a metaphor for her state of mind throughout the book. The first section‚ Solid‚ shows how Kate is a stable and strong person. The next section‚ Liquid‚ is a time where Kate’s life is very inconsistent and she is unsure about herself. The last section‚ Gas‚ shows how Kate has accepted her fate and tries to help everyone she can. A solid

The scientist we chose for our project is John Dalton. Who is John Dalton‚ you might ask? John Dalton was an English chemist‚ physicist‚ and meteorologist. He is best known for the discovery of the modern atomic theory. The rules for the atomic theory are that all matter is made up of tiny particles‚ or atoms‚ atoms are always invisible and indestructible‚ all atoms of a given element are identical in mass and properties‚ compounds are formed by a combination of two or more different kinds of atoms

[pic] TAKEING THE MYSTERY OUT OF THE TXV The thermostatic expansion valve has been considered by some to be a mysterious and complex device. As a result‚ many valves are needlessly replaced when the cause of the system malfunction is not immediately recognized. Actually the thermostatic expansion valve performs only one very simple function. –it keeps the evaporator supplied with enough refrigerants to satisfy all load conditions. It is not a temperature control‚ suction pressure control

react under certain conditions. These conditions‚ such as introducing a flame to the gas as well as oxygen and CO2‚ caused other reactions to occur. Experiment Before I began the experiment I gathered all my supplies from the given list in the lab manual. From there I began the actual experiment and diluted the HCL placed in a test tube and then placed the ZN in the tube as well. I placed the stopper and gas delivery plastic system on the test tube and arranged the tube in the well plate.
