Pure water is composed of two hydrogen molecules and one oxygen molecule, thus the formula H20.
Outside of a lab, it is quite unlikely that you will encounter pure water.

Water molecule consists of two hydrogen atoms and one oxygen atom.
Hard water is not pure water. It contains ions such as calcium ions and magnesium ions. calcium ions cause permanent hardness whereas, magnesium ions cause temporary hardness.
True, outside of a lab, natural water will always contain some chemical species, ions or undissolved microscopic materials that are not visible to the naked eye.

What are the elements found in water?
Hard water contains carbonates and bicarbonates of calcium and Magnesium.
Why is hard water less desirable than soft water?
Hard water contains more calcium and can casue scaling on heater elements found in dishwashers, kettle and washing machines.
At what ppm is what elements of hard water potentially hazardous?
Elements of hard water are potentially hazardous at about 0.3 to 1.5 PPM.
What 3 elements are found in water?

How many elements are found insae water?
84 Elements
What are the only three elements found in nature as a liquid?
Solid liquid gas. A solid is hard like ice. A liquid is water. A gas is water just boiled.
What elements make up hard water?
magnesium and calcium.
Elements found in water?
The only elements in pure water are those of which water itself is comprised ...hydrogen and oxygen. In impure water, any other elements that are themselvessoluble in water, or that are components of water-soluble compounds, or that areground up fine enough to be physically suspended in water, can also be found.
What are elements and where are they found?
element are fond in compounds and water
What elements are commonly found in decomposition?

What are the major trace elements found in water?
Al, Si
What elements are found in both carbohydrates and water?
