Typicall water hardness is caused from calcium and magnesium compounds dissolved in the water.
The term "hard water" is used to describe water that has a high mineral content, usually calcium and magnesium in the form of carbonates, but may include several other metals as well as bicarbonates and sulfates, (water with a low mineral content is known as soft water).
A high enough concentration of these metals in your water can cause white lime scales on surfaces which the water comes into contact with. Total water 'hardness' is reported as ppm w/v (or mg/L) of calcium carbonate (CaCO3). Water hardness usually measures the total concentration of calcium and magnesium, the two most common metal ions, although in some locations around the world iron, aluminium, and manganese may also be present at elevated levels. Calcium usually enters the water as either calcium carbonate (CaCO3), from limestone or chalk, or from mineral deposits of calcium sulfate (CaSO4).
The two natural elements found in water are hydrogen and oxygen.
Oxygen (O) and hydrogen (H) are the only two that are found in both.
Water is a compound made up of two elements: hydrogen and oxygen. Hydrogen and oxygen atoms combine to form H2O, which is the chemical formula for water. Water is a vital substance for life on Earth and is found in various natural sources, such as oceans, lakes, rivers, and even in the atmosphere as vapor.
Water (H2O) is composed of two elements: hydrogen and oxygen. Specifically, it contains two hydrogen atoms and one oxygen atom. Therefore, in terms of distinct elements, there are two elements in the substance water.
There are two elements in water. Hydrogen (H), and Oxygen (O). It is made up of two atoms of hydrogen and one atom of oxygen, therefore its molecular structure is written 'H2O'.

Water is a COMPOUND of two(2) elements, viz. Hydrogen(H) and Oxygen(O). These tqo elements are both found in the Periodic Table. The Periodic Table is a list of ELEMENTS, not compounds.
Hydrogen and Oxygen H20 is the element compound of water.
Hydrogen and Oxygen H20 is the element compound of water.
Oxygen (O) and hydrogen (H) are the only two that are found in both.
Water is made up of two atoms of hydrogen to each atom of oxygen.
Both carbohydrates and water contain the elements carbon, hydrogen, and oxygen. Carbohydrates have a specific ratio of these elements, while water is a simple compound with two hydrogen atoms and one oxygen atom.
Hydrogen is an element. Water is composed of two elements - Hydrogen and Oxygen. One water molecule has two atoms of hydrogen and one atom of oxygen. Hence, the alternative name for water- dihydrogen monoxide (DHMO).
the elements of water is two atoms of HYDROGEN and OXYGEN
Pattern and rhythm are two design elements found in the American flag.
Water (H2O) contains hydrogen and oxygen. There for its element sign id H2O. H2Os combination of atoms is 2 hydrogen atoms and one oxygen atom.
