Compound have constant composition whereas mixture have variable.
Now, water made by constant composition of hydrogen and oxygen (two atoms of hydrogen and one atom of oxygen) whereas air have many elements with variable composition.
The gasses that mix to make up air (oxygen, nitrogen, carbon dioxide, helium, argon, etc) do not combine chemically- they are still elements. However, with water, oxygen and hydrogen (elements) are chemically combined to create water- a compound.
It is a mixture of all the gasses in the atmosphere and water.
clouds is a mixture because the cloud is made of two types of chemicals + it also got water
air = solution milk = heterogeneous mixture water= compound
Pure substances are those that are composed of only one element or compound. Fog is made up of water, along with the various elements and compounds that make up the Earth's atmosphere. Therefore, fog is not a pure substance.
air is a mixture because it is made up of different gases
Water is the compound. Iodine and calcium are elements, and air is a mixture.
Air is a mixture, made mostly of the elements nitrogen and oxygen. It also has some other gases, such as argon (element), carbon dioxide (compound), and water (compound).
It is a mixture of all the gasses in the atmosphere and water.
Water is a compound of hydroogen and oxygen (H2O). Copper is an element, Air is a mixture of elements and compounds, and saline solution is a mixture of salt and water.
No. Air is a mixture.
Answer a. Pure Water is not a mixture - it is a compound. Seawater is a mixture of water and salts, air is a mixture of gases and brass is a mixture (an alloy) of copper and zinc metals.
Air is mostly composed of elemental substances or molecules. It is also called as a mixture of compounds and elements.Air is not a compound, but it isn't a particular element. Air is a mixture of gasses that do not react with each other.
Though fog is a colloid, many consider it to be a heterogeneous mixture of water and air.
mixture
Steam is a gaseous compound, ie. vaporous water eventually mixed (homogenously) with others like in air. However a heterogenous mixture of tiny water dropplets, which can be seen coming off a container with boiling water, is (erroneously) called steam, this is a heterogenous mixture of air (gas) and liquid (water). Real steam is invisible, and far more dangerous to get burnt from!
Air is a mixture of gases.
air is a mixture of elements (nitrogen, oxygen, trace amounts of other elemental gases) plus compounds (water vapor, nitrogen and sulfur oxides, CO2)
