The composition of air is approximately 78% nitrogen, 21% oxygen, and the remaining 1% includes carbon dioxide, some noble gases, and water vapor.
Water is the compound. Iodine and calcium are elements, and air is a mixture.
It is a compound because it is made of oxygen, hydrogen and other elements.
Yes look at air it has oxygen and nitrogen(elements) and carbon dioxide(compound)
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).
a compound is made when a reaction accours eg iron + heat + air = iron + oxide + air
No, air in a bottle is not a compound. Air is a mixture of different gases, including nitrogen, oxygen, carbon dioxide, and others. Compounds are substances formed by the chemical combination of two or more elements in fixed proportions, which is not the case with the gases in air.
No. Air always contains two elements, oxygen and nitrogen, neither of which is a compound, although they occur as diatomic molecules.
mixture
A compound is composed of two or more elements. A compound of only two elements is a binary compound.
because there are many elements and compounds in that make it up, eg, CO2 is a compound, but O2 is an element. This means its a mixture not an element.
A chemical formula shows what elements a compound contains, and the ratio of the atoms or ions of the elements in the compound.
Air is a mixture of several gaseous elements, such as oxygen and nitrogen, and compounds, such as carbon dioxide. In the sense of the four elements, water, fire, earth, and air, air is an element.
