Will xenon react with nitrogen and why

Andreyy89

No, xenon wont react with nitrogen.

This is because xenon is a noble gas and noble gases only react with other elements under very unusual circumstances.

I hope this has helped you.

What are the first three overtones of a bassoon that has a fundamental frequency of 90.0 Hz? It is open at both ends. (The overt

vekshin1

Answer:

$f_{2}=180Hz,f_{3}=270Hz,f_{4}=360Hz\\$

Explanation:

Given data

Frequency f=90 Hz

To find

First three overtones of bassoon

Solution

The fundamental frequency of bassoon is found by substituting n=1 in below equation

f=v/λ=nv/2L

$f_{1}=v/2L$

The first overtone of bassoon is found by substituting n=2

$f_{2}=2v/2L\\f_{2}=2(v/2L)\\as \\f_{1}=v/2L\\So\\f_{2}=2f_{1}\\f_{2}=2(90Hz)\\f_{2}=180Hz$

The second overtone of bassoon is found by substituting n=3

$f_{3}=3v/2L\\f_{3}=3(v/2L)\\as \\f_{1}=v/2L\\So\\f_{3}=3f_{1}\\f_{3}=3(90Hz)\\f_{3}=270Hz$

The third overtone of bassoon is found by substituting n=4

$f_{4}=4v/2L\\f_{4}=4(v/2L)\\as \\f_{1}=v/2L\\So\\f_{4}=4f_{1}\\f_{4}=4(90Hz)\\f_{4}=360Hz$

What is the primary function of earth's atmosphere (1 point)?

lana66690 [7]

Without the atmosphere that protects the Earth, humans, animals and all plant life would not be able to survive. The atmosphere works to hold oxygen in the area around the earth. Humans and most animals are dependent on oxygen. Plants are also dependent on oxygen because they take the leftover carbon dioxide from humans when they inhale the oxygen.
