Engineers test the safety of a new car by running a crash test, which shows whether the airbags inflate properly. When the car detects a crash, a small amount of sodium azide (NaN3) stored behind each airbag is heated. The sodium azide breaks down into sodium metal (Na) and nitrogen gas (N₂). The nitrogen gas inflates the airbags in less than one-tenth of a second! This design helps to keep people inside cars from getting seriously injured in a crash.
Complete the table to classify the substances in this chemical reaction.
Answer:
Under normal circumstances, this molecule is quite stable. If heated, though, it will fall apart. The chemical equation 2 NaN3 --> 2 Na + 3 N2 describes exactly how it falls apart. Notice that the second product of the above reaction is N2, also known as nitrogen gas. A handful (130 grams) of sodium azide will produce 67 liters of nitrogen gas--which is enough to inflate a normal air bag.
Explanation: Because of mathmaticsit works
Nitrogen gas (N2) and sodium metal (Na) are the products of the breakdown of sodium azide.
What is metal?Metal is defined as a solid with good electrical and thermal conductivity that is often hard, glossy, malleable, fusible, and ductile. The majority of metals are ductile and malleable, and they are often denser than other elements. The materials that have a propensity to donate electrons are metals. They have an electropositive makeup.
Airbags are inflated by nitrogen gas in less than a tenth of a second! Because to this design, occupants of cars are less likely to suffer severe injuries in collisions. Sodium azide, often known as NaN3, is the principal chemical involved in the air bag reaction. As a result of the heat produced, sodium azide breaks down into sodium metal and nitrogen gas, inflating the car's air bags.
Thus, nitrogen gas (N2) and sodium metal (Na) are the products of the breakdown of sodium azide.

7. Mateo and Jackie were on a playground rolling some different-sized balls to get them to crash. They used a tennis ball (the same mass) in both crashes. They tried two soccer balls—a pink one (more mass) for Crash 1 and a blue one (less mass) for Crash 2. Mateo and Jackie want to know what happened to the tennis ball. Use information from the diagram to answer. In which crash did the tennis ball experience a stronger force? How do you know?
Answer:
The answer is Crash 1, because the pink soccer ball had a greater amount of mass so it would expirence a stronger force.
Hope this helps! :)
Answer:
crash 1
Explanation:
Because crash one has a higher mass which will have a bigger force or hit because it weighs more
for example when i shoot an arrow harder then i shoot an arrow slower which will make it farther the arrow because i gave it more energy with more force

Please write an introduction for a SHE task of Fire-Stick Farming.
Fire stick Managing the environment through farming Aboriginal people routinely burned grass to minimise fuel and promote new growth in order to attract grazing animals for hunting.
Why is farming important?Among the various ways that agriculture has an impact on society are the provision of food, habitat, and employment opportunities; the provision of raw materials for food and other goods; and the development of robust economies through commerce.
Why is farming beneficial to the environment?A large number of species use pasture and crops as both a habitat and a source of food, making up around 50% of the planet's livable land. Sustainable management of agricultural operations has the potential to safeguard watersheds, restore significant habitats, and improve the quality of the soil and water supply.
