Question

Chemical reactions are the atmosphere of the triangle

Answer 1

Answer:

In the stratosphere, ultraviolet light reacts with O 2 molecules to form atomic oxygen. Atomic oxygen then reacts with an O 2 molecule to produce ozone (O 3). As a result of this reaction, the stratosphere contains an appreciable concentration of ozone molecules that constitutes the ozone layer.

Answer 2

1 km = 1000 m

1 hour = 60 minutes

= 60 × 60 s

= 3600 s

s stands for seconds
