No, it is a gas-solid mixture when view as a whole.
It has a solid component (the balloon itself), and a gas component (the helium)
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.
The common matter in a balloon is air, typically a mixture of gases such as nitrogen, oxygen, and trace amounts of other elements. When inflated, the air exerts pressure on the walls of the balloon, causing it to expand and float.
A mixture of oxygen, nitrogen, carbon dioxide and other various gases. The only reason is floats is because the hot gas inside the balloon is lifting it up.
When you blow into a balloon, the gas that fills it is primarily carbon dioxide. This gas is produced when you exhale, as your body converts oxygen from the air into carbon dioxide as a waste product. Additionally, the balloon also contains some air, which is a mixture of gases including nitrogen and oxygen.
Nearly any gas can pump up a balloon because it has mass. However, helium is used because it is lighter than air, makes balloons rise, and is fairly safe. Sure, you could put hydrogen in a balloon and it would rise, but it would be highly explosive.
Because they can
When helium is added to a balloon, it decreases the overall density of the balloon compared to the surrounding air. This causes the balloon to float because the buoyant force exerted by the helium is greater than the force of gravity acting on the balloon. This buoyant force allows the balloon to rise in the air.
because helium has less density
heilum is lighter
Gas to liquid is called "condensation."
Soild
Yes, the air in a balloon is a mixture. It is primarily composed of nitrogen, oxygen, and small amounts of other gases like carbon dioxide and argon.

No. That would be a mixture. If you were to burn that mixture you would get water as a product. Water is a compound.
light bulbs - neon balloons - heilum
Helium is an element (and therefore a pure substance) yes
