Answer:
Kr
Explanation:
Now we have to apply Graham's law of diffusion in gases
t1/t2 = √M1/M2
If t1 is the time of diffusion of Xe = 75 seconds
t2 is the time of diffusion of the unknown gas = 60 seconds
M1= molar mass of Xe=131.293
M2= molar mass of the unknown gas
Thus;
75/60 = √131.293/M2
(75/60)^2= (√131.293/M2)^2
5625/3600=131.293/M2
M2= 3600×131.293/5625
M2= 84.0
The unknown gas is krypton (Kr)
Airbags are good for car crashes and have saved lots of life’s, the force of the airbags are dangerous though because they come out with fast acceleration and when it is hot it can burn you. If there is ever a time for collision airbags may save your live!

Answer:
1) HBr; 2) NaCCH; 3) O3; 4) H2O
Explanation:
The first step is formation of alkyl halide followed by reaction with sodium acetylide, to form 3-methylbutene, which is then followed by oxidation reaction with O3& H2O to 3-methylbutanal
Answer:
what can you give more details of what this is i would like to help
Explanation:
(1) Metal
All metals ionize easily, ex. Sodium forms Na+ easily as it has a very low first ionization energy, and all metals easily conduct electricity as they are very good at ionization and can thus move electrons from one atom to another.
