Because air is not boUnd chemically it is just a mixture of oxygen nitrogen and other gases while water molecules are one oxygen atom combined chemically to two hydrogen atoms
Water is the compound. Iodine and calcium are elements, and air is a mixture.
Compound
Exhaled air is a mixture of various gases, primarily nitrogen, oxygen, carbon dioxide, and traces of other gases like argon and water vapor. It is not a compound or element on its own, but rather a combination of different gases.
Sea water is a combination of water and various dissolved substances, so it is not considered an element. Air is a mixture of gases like oxygen, nitrogen, and others, and is also not an element. Water, however, is a compound made up of the elements hydrogen and oxygen.
A mixture of chlorine gas and air is a homogeneous mixture because the components are uniformly distributed, while a mixture of oil and water is a heterogeneous mixture because the components do not uniformly mix and form separate layers due to their different chemical properties. Additionally, chlorine gas and air are both gases, while oil and water are liquids.
Water is a compound composed of hydrogen and oxygen atoms, while air is a mixture of gases primarily composed of nitrogen and oxygen. So, water is a compound, while air is a mixture.
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).
Foggy air is a mixture because it is composed of water droplets suspended in the air. It is not a pure substance with a fixed composition, so it does not qualify as an element or a compound.
air = solution milk = heterogeneous mixture water= compound
No, water is not considered a form of air. Air is a mixture of gases, primarily nitrogen and oxygen, while water is a liquid compound made up of hydrogen and oxygen molecules.
Steam is a compound. Its molecule is comprised of two hydrogen atoms bound with one oxygen atom. Steam is the vapor phase of the compound. The liquid and solid phases are known, respectively, as 'water' and 'ice'.
No. Air is a mixture.
Gold is a pure substance (element), water is a compound, steel is an alloy, and air is a mixture of gases.
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.
Though fog is a colloid, many consider it to be a heterogeneous mixture of water and air.
