Helium in a balloon is considered a pure substance because it is composed of only helium atoms. It is not a mixture because there are no other substances mixed with the helium in the balloon.
A balloon filled with helium is a pure substance, specifically an element. Helium is a chemical element with the symbol He and atomic number 2, consisting of only one type of atom.
Helium is usually the gas inside an air balloon. It is lighter than air and helps the balloon float.
No, a helium balloon is not a solid. It is a gas-filled flexible container made of materials like latex or mylar.
Helium is typically pumped into balloons because it is lighter than air and gives the balloon its ability to float.

No, a helium balloon is not a gas-liquid mixture. It is filled with helium gas, which is a pure gas. The gas fills the balloon to make it float.
Helium gas is a pure substance
Helium gas is 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.
Helium is a pure substance
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.
Neither. Helium is not a mixture at all, it is a pure substance.
