because it filters all of the air and makes it easy to breath.
Oxygen is a solvent and if you want to know what a helium is then it is a solute.
Yes as the oxygen (gas) can be compressed into the very small container which is a property.
Hydrogen gas would evolve from the cathode and oxygen gas would evolve from the anode.
The simple answer to your question is "maybe." Solutions are defined as a homogenous (uniform) mixture of 2 or more substances. In a solution, a solute is dissolved into another substance known as the solvent. When referring to a solution in chemistry, one is often referring to a mixture of 2 or more liquids, however solutions may be composed of mixtures of a solid, gas or liquid. In cases of liquid and solid solvents, another substance (the solute) in a gas, liquid or solid phase may be dissolved into the solvent to make a solution. Solutions of gases can only be made with mixtures of substances in the gas phase. 78% nitrogen gas and 21% oxygen gas may be considered a solution if these 2 gases are homogenously mixed with another gas (or gases) that make up the remaining 1%. The mixture of 78% nitrogen and 21% oxygen refers to the composition of the atmosphere of Earth or air. In reality air is not considered a solution as it contains many impurities which make it a heterogenous mixture.
no
oxygen
Nitrogen and oxygen = Air
Yes, it is a gas
Yes, oxygen gas can be considered a solution in certain chemical reactions or processes, such as when it dissolves in water to form oxygen gas in solution.
Oxygen gas is pumped into a small container to displace any other gases present, creating an oxygen-rich environment. This can be useful for enhancing combustion processes, preserving perishable items, or supporting aerobic organisms that require oxygen to survive.
Solutions in which solute and solvent both are gases; are called Gas-gas Solutions. For example - solution (mixture) of nitrogen and oxygen, solution (mixture) of carbon dioxide and nitrogen, solution (mixture) of carbon dioxide and oxygen, etc.
Yes, a lot of oxygen gas can be pumped into a very small container using high-pressure tanks or compression techniques. However, there is a limit to how much oxygen gas can be contained in a small volume due to the physical properties of gases and the container's capacity. Overfilling the container can lead to safety hazards like explosion or leakage.
Air. (Oxygen, Carbon Dioxide)
Such a gas-gas mixture is, technically, a solution but most people do not use that term to describe it.
Oxygen in the lungs and passes through the alveoli, small sacs which allow gas exchange, and enters the blood to be pumped throughout the body.
A solution that is composed completely of gas is carbon dioxide. Hydrogen dioxide is also a solution composed completely of gas.
Fish breathe through their gills, extracting dissolved oxygen from water. This process is possible due to the fish having specialized structures in their gills called lamellae, which increase the surface area for gas exchange. The oxygen in water is in the form of a solution, specifically a solution of oxygen gas in water.
