Hard water contain calcium bicarbonate, magnesium bicarbonate in temporary hard water and calcium/magnesium sulfate in permanent hard water. Soft water contain doesn't contain these substances or only in very limited concentations.
No, talc is not a metal. It is a mineral composed mainly of magnesium, silicon, and oxygen.
Magnesium is found in living things in various organs and tissues, with the highest concentration being in bones, muscles, and soft tissues. In humans, the average adult body contains about 25 grams of magnesium, with about 50-60% found in the bones, 40% in muscle tissue, and the remainder in soft tissues and fluids.
Alkali Metals are soft enough to be cut with a knife.Alkali Metals:LithiumSodiumPotassiumRubidiumCesiumFrancium
Water in County Durham is generally hard. This means it has a high mineral content, particularly calcium and magnesium ions, which can leave residue on surfaces like faucets and dishes.
Magnesium is a soft metal: the Mohs hardness is approx. 2.
There are soft.
hard
Hard water contain sulfates of calcium and magnesium, sometimes chlorides.Soft water contain calcium and magnesium bicarbonates.
Hard water has a significative concentration of soluble calcium or magnesium salts and possible other salts. Soft water is significantly more pure.
Hard water contains bicarbonates of calcium and magnesium or sulphates and chlorides od calcium and magnesium . It can be converted to soft water by boiling or by adding calculated quantity of calcium hydroxide .
Hard water contain calcium bicarbonate, magnesium bicarbonate in temporary hard water and calcium/magnesium sulfate in permanent hard water. Soft water contain doesn't contain these substances or only in very limited concentations.
Magnesium is a soft metal that has a low shear strength, making it prone to deformation rather than cleanly cutting when subjected to a knife blade. Additionally, when magnesium is cut, it easily reacts with oxygen in the air, forming magnesium oxide which can be a hindrance to cutting.
Because of the presence of Calcium and Magnesium salts.
No, talc is not a metal. It is a mineral composed mainly of magnesium, silicon, and oxygen.
Magnesium and palladium are both metals; they both have the usual silvery appearance of metals, and are both very electrically conductive. Other than that they are very different. Magnesium is soft and reactive, palladium is hard and inert.
Magnesium is found in living things in various organs and tissues, with the highest concentration being in bones, muscles, and soft tissues. In humans, the average adult body contains about 25 grams of magnesium, with about 50-60% found in the bones, 40% in muscle tissue, and the remainder in soft tissues and fluids.
