Answer 1

Air is mainly a mixture of two gases.

Step-by-step explanation:

Air is mainly a mixture of two gases, nitrogen (around 78%) and oxygen (around 21%). It also contains carbon dioxide (around 0.03%), noble gases (around 0.9%), water vapour and a very small amount of other kinds of gases. Air makes up the atmosphere, which is essential for life on Earth.

(FYI, argon has the highest percentage of composition among the noble gases)
