Is helium in a balloon a pure substance not a mixture?
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.
Is a balloon full of helium a compound element or a mixture?
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.
What gas is inside an air balloon?
Helium is usually the gas inside an air balloon. It is lighter than air and helps the balloon float.
Is a helium balloon a solid?
No, a helium balloon is not a solid. It is a gas-filled flexible container made of materials like latex or mylar.
Which gas is pumped into a balloon?
Helium is typically pumped into balloons because it is lighter than air and gives the balloon its ability to float.

Is a heilum balloon a gas-liquid mixture?
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.
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 gas a mixture or substance?
Helium gas is a pure substance
Is helium gas substance or mixture?
Helium gas is a pure substance
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 is pure or mixture?
Helium is a pure substance
Is helium gas a homogeneous mixture or heterogeneous mixture?
Neither. Helium is not a mixture at all, it is a pure substance.
Is helium gas a homogeneous mixture or a heterogeneous mixture?
Neither. Helium is not a mixture at all, it is a pure substance.
Is helium a pure substance or a homogeneous or heterogeneous mixture?
Helium is a pure substance because it is composed of only one type of atom (helium atoms). It is a noble gas with a uniform composition throughout, making it a homogeneous substance.
Is helium gas mixture or pure substances?
Helium gas is a pure substance
