Something is homogeneous if it is the same from one location to the next and heterogeneous of the properties change with position in the substance.
A homogeneous mixture is any mixture that shows no separation of components. It is uniform in chemical composition with no physical separation of components.
For example, water and sugar will mix with each other. We say sugar dissolves in water.
Heterogeneous mixtures are mixtures that result from combining things which do not entirely mix. Oil and water do not mix completely and even if the mixture is agitated strongly, the two components will separate.

Something is homogeneous if it is the same from one location to the next and heterogeneous of the properties change with position in the substance.
A homogeneous mixture is any mixture that shows no separation of components. It is uniform in chemical composition with no physical separation of components.
Heterogeneous mixtures are mixtures that result from combining things which do not entirely mix. Oil and water do not mix completely and even if the mixture is agitated strongly, the two components will separate.
Here are some examples of Heterogeneous mixtures.
Sand & water (liquid & solid),
Carbonated beverage like soda or beer (gas & liquid),
Orange Juice with pulp in it (liquid & solid),
Water with ice cubes in it (liquid & solid),
Chicken noodle soup (liquid & solid),
Oil & water (immiscible liquids),
Salad (solids & solids),
Trail mix (solids & solids),
Granite (solids in a solid),
Table salt crystals & sugar crystals (solids & solids),
Table salt crystals & iron filings (solids & solids),
Colloids
Here are some examples of Homogeneous mixtures.
Salt dissolved in water,
Soapy water,
Hydrochloric acid & water,
Alcohol & water,
Sugar dissolved in water,
Ammonia water,
Phenolphthalein dissolved in alcohol and water,
Extracts of coffee beans,
Extracts of tea leaves
Neither. Helium is not a mixture at all, it is a pure substance.
Helium is an element which makes it a pure substance.
Neither. The condensation of oxygen gas is a phase change. The oxygen itself would be an element, not a mixture.
A. Compound. C:
No, helium is a pure substance and an element to be more specific. It has a constant composition making it a pure substance and it is homoatomic (has only one type of atom) which makes it an element.
Neither. Helium is not a mixture at all, it is a pure substance.
Neither. Helium is not a mixture at all, it is a pure substance.
Helium is an element which makes it a pure substance.
Methane gas is homogeneous because it is a single phase mixture where the composition is uniform throughout.
If the sugar does not dissolve it the oil, then it is not
It depends. You can have a gaseous mixture such as air, which would be a homogeneous mixture. But a single gas such as oxygen or methane would be a pure substance.
Neither. The condensation of oxygen gas is a phase change. The oxygen itself would be an element, not a mixture.
Carbonated soft drinks with bubbles are considered heterogeneous because they are composed of different components that can be visually distinguished, such as the liquid and gas bubbles present in the drink.
A. Compound. C:
No. It is an element, which is homogeneous matter.
is heterogenous because it is composed of many different gases. To be homogenous it would have to be composed of a single gas.
Xenon gas is an element. It is a noble gas found on the periodic table with the atomic number 54.
