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.
What else can I help you with?
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 helium and air a heterogeneous mixture?
No. It will be a homogeneous mixture of gases.
Why Pure Air Is Homogeneous Or Heterogeneous?
Pure air is homogeneous because all components are completely miscible.
When the balloon is up in the air the burner is turned off and the balloon drifts along with the wind What will eventually happen to the air inside the balloon?
As the balloon cools down, the air inside will also cool. This will cause the air pressure inside the balloon to decrease, potentially leading to the balloon descending back to the ground due to the decreased pressure.
Is smog heterogeneous?
Yes, smog is considered a heterogeneous mixture because it consists of a variety of pollutants and particles suspended in the air. These components can vary in size, composition, and distribution throughout the smog, making it heterogeneous.
What gas is inside an air balloon?
Only a hot mixture of the same gases that are in the air you breathe.
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.
What is the air inside a balloon?
The air inside a balloon is a mixture of gases, typically consisting of nitrogen, oxygen, carbon dioxide, and trace amounts of other gases. When the balloon is inflated, the pressure of the air inside the balloon is higher than the atmospheric pressure outside, causing the balloon to expand and float.
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 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?
City air is a heterogeneous mixture because it contains a variety of different gases, particles, and pollutants that are not evenly distributed throughout the air.
When you heat the air inside a hot air balloon, it rises. Why does this occur?
D: The hot air inside the balloon becomes less dense than the air outside the balloon.
Is cake butter a homogeneous or heterogeneous mixture?
No, it is heterogeneous as there are still pockets of air in the cake itself.
