If a chemical reaction produces a gas, and the bag is close of, then the bag will inflate.

Take the exmaple of vinegar and baking soda:

CH3CO2H + NaHCO3 --> NaCH3CO2 + H2O + CO2

The CO2 released is a gas, which can inflate a bag.

What are two physical properties and two chemical properties of a bag of microwave popcorn before popping and after?

Two physical properties of a bag of microwave popcorn before popping are its mass and volume, which remain constant before and after popping. Two chemical properties that change after popping are the composition of the kernels, which undergo a chemical reaction to turn into fluffy popcorn, and the release of aroma compounds due to the Maillard reaction during popping.


Does temperature have effect on efficiency of air bags?

Temperature can affect the efficiency of air bags because extreme temperatures can cause air bag components to deteriorate, making them less effective in a crash. High temperatures can also increase the pressure inside the air bag system, potentially leading to premature deployment or damage. It is important to store and operate air bags within the manufacturer's specified temperature range to maintain their efficiency.


What is the chemical change when a paper bag rips?

When a paper bag rips, the chemical composition of the paper does not change. The ripping of the paper bag is a physical change, where the arrangement of the paper fibers is altered, but the chemical bonds between molecules remain the same.


Why don't mixture have chemical formulas?

Mixtures do not have chemical formulas because they are not chemical bonded. Mixtures can be physically separated like a bag of different colored marbles.


What pressure will make a bag explode?

The pressure required to make a bag explode depends on a variety of factors, including the material the bag is made of and its thickness. However, a common range is 2 to 4 times the normal atmospheric pressure.

What different temperature water affects how fast the bag inflates?

The higher the temperature of the water, the faster the bag will inflate. This is because the reaction between the baking soda and vinegar that causes the bag to inflate is faster at higher temperatures. Conversely, lower temperature water will slow down the reaction and the inflation process.


What is air bag stoichiometry?

Air bag stoichiometry refers to the chemical reaction that takes place inside an airbag inflator system to rapidly generate nitrogen gas to inflate the airbag during a crash. The process involves the decomposition of a solid chemical propellant to produce gas, which inflates the airbag within milliseconds to protect the occupants.


Do you want to have any chemicals left over in an air bag after it inflate?

No, it is undesirable to have any residual chemicals left in an airbag after it has inflated as it can be harmful if exposed to the skin or eyes of vehicle occupants. The design of airbags aims to efficiently deploy and inflate using a gas-producing chemical reaction that results in complete inflation.


How do you inflate a speed-bag?

To inflate a speed bag, locate the small air valve on the bag and insert a pump needle. Use a hand pump or air compressor to slowly inflate the bag until it feels firm but still has some give when punched. Be sure not to overinflate the bag to prevent damage.


How long does it take for an air bag to inflate?

An airbag typically takes about 20 to 30 milliseconds to fully inflate after a collision is detected. The rapid deployment is crucial for providing immediate protection to occupants during a crash, as the airbag needs to inflate before the occupant makes contact with the vehicle's interior. This quick inflation is achieved through a chemical reaction that generates gas, allowing the airbag to expand almost instantaneously.


What is an airbag filled with?

You mean a safety airbag in a car? A chemical reaction fills the bag with nitrogen.


Will air bag inflate in a car if seat belt is not fasten?

yes


What des sodium hydrogencarbonate do to the air inside the plastic bag?

Sodium bicarbonate (baking soda) can react with carbon dioxide in the air inside a plastic bag, causing the bag to inflate or puff up as gas is produced. This reaction can be used to create a simple homemade model of a volcano erupting.


How many seconds does an airbag take to inflate?

Once activated, the air bag will fully inflate in 1/25 of a second or 40mil seconds.


What is the conclusion of The Exploding Lunch Bag experiment?

The experiment is another example of the chemical interaction between acids and bases. In the experiment, a closable plastic lunch bag is filled with warm water and vinegar, and a wrapped packet of baking soda is added. The bag is closed and the reaction between acid (vinegar) and baking soda (base) creates pressure by generating gas (carbon dioxide) within the bag. The bag swells and usually explodes (ruptures) unless the pressure escapes. This shows that a chemical reaction can indirectly release energy as it forms new chemical compounds.


How many inches of space does the air bag need to inflate?

space between is 25cm


How does an air bag work?

If you run into something, your air bag can inflate in less than a tenth of a second to protect you from the forces of a head-on collision.
