Physical and chemical procedures: filtration, distillation, centrifuging, sieving, chemical reactions, crystallization, etc.
No, argon gas is a pure substance and not a heterogeneous mixture. A heterogeneous mixture contains different substances that are visibly distinguishable, whereas argon gas is composed of only argon atoms.
There are three ways. Some mixtures are gases themselves, and air is the most common one. Some mixtures are partly gases and partly liquids. Also, gases can dissolve into liquids, like oxygen in water.
An aloy is an example of a homogenous (metallic) solid mixture.
A mixture is a combination of different substances that remain as individual substances and can be separated by physical means. Examples include a mixture of salt and sand, where you can separate them through processes like filtration or evaporation.
The statement in the question is false. It is very common for two liquids to form a mixture that is also liquid, and, unless a chemical reaction occurs, a mixture of two gases always is also a gas.
Helium gas is a pure substance
No, argon gas is a pure substance and not a heterogeneous mixture. A heterogeneous mixture contains different substances that are visibly distinguishable, whereas argon gas is composed of only argon atoms.
yes gas masks were used
There are several company's selling and inventing new gas masks.
yes you did they were called mick mouse gas masks they were for children

homogeneous mixture
An aloy is an example of a homogenous (metallic) solid mixture.
A type of mixture in which different materials are spread out unevenly is known as a heterogeneous mixture. It is a combination of substances with no uniform composition or properties.
15 grams of oxygen gas and 22 grams of nitrogen gas together form a mixture, not a compound. A mixture is a physical combination of two or more substances that retain their individual properties, while a compound involves a chemical combination of elements in fixed ratios.
You don't put gas into gas masks. They are used to keep out poisonous gases.
Assuming by heating gas you mean "natural" gas, the the formula would be CH4 which is methane. Natural gas is mostly methane with some other combustible hydrocarbons added in.
