The sun is a star made primarily of hydrogen and helium gases undergoing nuclear fusion, making it a homogeneous mixture of elements.
The oxygen and helium in a scuba tank are considered a homogeneous mixture, not a compound or a heterogeneous mixture. In this case, the gases are mixed together uniformly, and their individual properties remain unchanged. A compound consists of two or more elements chemically bonded together, while a heterogeneous mixture would have distinct, separate components.
Yes for sure, but in the very small amount, the composition of air is approximately : 78.08 % Nitrogen 20.94 % Oxygen 00.93 % Argon 00.03 % Carbon Dioxide which is equal to 99.98 percent the rest of the air is compose of Neon Helium Krypton Sulfur dioxide Methane Hydrogen Nitrous Oxide Xenon Ozone Nitrogen dioxide Iodine Carbon monoxide Ammonia In which Helium's composition is 5.2 parts per million.
Helium is an element not a mixture.
