Why water is considered as compound not a mixture?

Water is a compound because it is made up of water molecules. There is no such thing as water atoms. Water molecules are made of hydrogen and oxygen atoms, in the definite proportion of two hydrogens for one oxygen.

Why is water a mixture?

A mixture is when two or more substances combine physically together. However, in water, two hydrogen atoms combine with one oxygen atom chemically, forming a new substance that has properties different from hydrogen alone or oxygen alone.

Why is water not a homogeneous mixture?

Heterogeneous mixtures are made up of a non-uniform composition, while homogeneous mixtures are made up of a uniform composition. For example, water and sand is a heterogeneous mixture — you can easily separate the sand from the water.

Is water is a mixture or not?

(A) Water from public taps is often treated with chemicals to make it safe for drinking. Seawater is a mixture of many different substances. Some of these substances can be observed when the water in seawater evaporates and leaves behind salt. Water, H2O, is a pure substance, a compound made of hydrogen and oxygen.

Why water is a compound not a mixture Class 9?

Answer: Water is a compound and not a mixture because Its properties are completely different from that of oxygen and hydrogen, its constituent elements.

Is water considered a compound?

The chemical formula for water is H2O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms. Thus, water is a compound. It’s also a molecule, which is any chemical species formed by two or more atoms chemically bonded to each other.

Is water a mixture, or a pure substance?

Water is a pure substance as much as pure Oxygen is pure oxygen. If you have air dissolved in the water, it is indeed a mixture or if you have salt dissolved, it is then a solution. Pure degassed water is a pure substance.

Is water considered a homogeneous mixture?

Here are some homogeneous mixtures: Water itself is an example of a homogeneous mixture. It often contains dissolved minerals and gases, but these are dissolved throughout the water. Tap water and rain water are both homogeneous, even though they may have different levels of dissolved minerals and gases.

Is water a mixture element or molecule?

Water is a molecule because it is made from atoms that have been chemically combined. It is also a compoundbecause the atoms that make waterare not all the same – some are oxygen and some are hydrogen. Similarly, is air a mixture or compound or element?
