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 element along with Barium that can be found in hard water is Calcium. Calcium contributes to the total hardness in water and does not cause any ill health effects. On the other hand, Barium can cause serious toxic effects to the heart and blood vessels in large concentrations.
The two elements that can be found in hard water are magnesium and calcium. Hard water is considered if it has a hardness of 100mg/L. This also has a concentration of calcium and magnesium.
Hardness of water is mainly caused by Ca2+ ions, also Mg2+, Fe2+, Mn2+ ions

Oxygen (O) and hydrogen (H) are the only two that are found in both.
Calcium and iron deposits within the water are harmless and often colorless unless the iron content is large (think rust color). These two elements are creators of 'hard water'.
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.
The two biggies are Oxygen and Hydrogen. Traces can also be found of air, nitrogen, CO2, CO, CH3 and other gases in the atmosphere.
The element found in a water molecule is hydrogen (H) and oxygen (O).
Bullseye and Elektra.
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 contains hydrogen and oxygen. Sugar contains carbon, hydrogen and oxygen.
Water is made up of two atoms of hydrogen to each atom of oxygen.
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).
Calcium and iron deposits within the water are harmless and often colorless unless the iron content is large (think rust color). These two elements are creators of 'hard water'.
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.
