The chemical at the heart of the air bag reaction is called sodium azide, or NaN3. CRASHES trip sensors in cars that send an electric signal to an ignitor. The heat generated causes sodium azide to decompose into sodium metal and nitrogen gas, which inflates the car's air bags.
Answer:
9.0 mol
Explanation:
- C₂H₄(g) + 3O₂(g) → 2CO₂ (g) + 2H₂O (g)
In order to <u>convert from moles of CO₂ to moles of O₂</u>, we need to use the <em>stoichiometric coefficients</em> in the balanced reaction. We use a conversion factor that has moles of CO₂ in the denominator and moles of O₂ in the numerator:
- 6.0 mol CO₂ *
= 9.0 mol O₂
1.) N3Cl
2.) Ionic because Cs is a metal and PO4 is a nonmetal
Answer:
Average Molar mass is 114.8u
Explanation:
» From the formula of average Relative Atomic Mass [ RAM ]
» We have two isotopes of Indium,
- Indium-113, mass » 112.9u, % » 4.28%
- Indium-115, mass » 114.9u, % » 95.72%
Answer:
D. to predict the effects of human population on the supply of natural resources
Explanation:
From the available graph, it can be seen that Natural resources and human population are directly proportional to each other. As the human population increases, the natural resources decreases, until they both finally meet up.
Hence, in this case, the correct answer is that the role of science in this study is "to predict the effects of human population on the supply of natural resources."
