This is a tough question... Some chemists will say both.
For example, you could argue that air in a balloon is a heterogeneous mixture. We say it is heterogeneous because it is made up of many different types off substances. For example, air is about 78% Nitrogen, 21% Oxygen and 1% Argon. In addition it has very small amounts of other molecules like water and carbon dioxide. It also contains dust and other aerosols. Because it is made of so many different things, it is a heterogeneous mixture,
On the other hand, it acts like a homogeneous mixture. When you observe air, you don't see all the individual pieces that make it up. You see an overall mixture. When it travels (like when wind blows) it does so as one big group. On the surface of the earth, it doesn't separate at all. (It does separate as you go higher in the atmosphere, past the mesosphere where it definitely becomes heterogeneous.)
If you are asking this as a high school student taking a chemistry course, I'd venture to say that your teacher wants you to call it a homogeneous mixture of gasses. Even though it's made of different compounds that act independently of one another on certain occasions (like when you burn a match you are only burning oxygen.... not argon or nitrogen), many say it's homogeneous.

Is helium inside a balloon a pure substance or mixture?
Natural air is always a mixture, and more or less homogenous in its major constituents. However, if the balloon was inflated by mouth, it will have less oxygen and more carbon dioxide than the air outside the balloon, which is also a mixture.
Is air a homogeneous or heterogeneous mixture?
Airt is a homogeneous mixture.
Is air in your house a homogeneous or heterogeneous mixture?
solution, which is a homogeneous mixture
Is helium and air a heterogeneous mixture?
No. It will be a homogeneous mixture of gases.
Is smog an element compound or mixture?
Smoke is a rather complex mixture of elements and several compounds, some gasses, some solids.
What gas is inside an air balloon?
Only a hot mixture of the same gases that are in the air you breathe.
When you blew a birthday balloon what gas will it be inside the balloon?
Imagine inhaling to blow in a balloon. You will take in air, hold it in your mouth and blow it into the balloon. Some of it will be the carbon dioxide you were exhaling but most of it will be the air you just breathed in. So, the gas inside the balloon will be a mixture, that is, air.
Is air a homogeneous mixture or a heterogeneous mixture?
Air is a homogeneous mixture.
Is air a heterogeneous mixture or a homogeneous mixture .?
Air is a homogeneous mixture.
Is air a heterogeneous or a homogeneous mixture?
Air is a homogeneous mixture.
Is air homogeneous mixture or heterogeneous mixture?
homogeneous
Is the air inside a balloon a pure substance?
In a helium balloon- one that floats and rises to the ceiling it is elemental helium that is used to inflate the balloon. If you just blow into a balloon to inflate it then it is air inside the balloon which is a mixture of gases, principally nitrogen and oxygen (both elements). There are also other gases that are chemical compounds such as carbon dioxide.
Is helium inside a balloon a pure substance or mixture?
Natural air is always a mixture, and more or less homogenous in its major constituents. However, if the balloon was inflated by mouth, it will have less oxygen and more carbon dioxide than the air outside the balloon, which is also a mixture.
Is air hetero or homo mixture?
Containing dust air is a heterogeneous mixture.
Is an air inside a balloon a pure substance?
The air inside a hot air balloon is the same as normal air around the balloon and the air you're breathing, only heated by the flame inside the balloon, hence HOT AIR balloon.
Is city air heterogeneous mixture or homogeneous mixture?
homogeneous
Is air a homogeneous or heterogeneous mixture?
Airt is a homogeneous mixture.
