What are the Causes of Hard Water and Hard Water

However it’s the percentages of those mineral salts that make water either ‘hard’ or ‘soft’. Basically, high amounts of minerals, such as calcium and magnesium, classify water as hard. You can often find a large amount of iron, manganese, sodium and other dissolved compounds such as bicarbonates and sulphates in hard water also.

Aluminium oxide | Drug Information, Uses, Side Effects

Inhalation exposure to 100 mg/hr aluminium, in the form of powder, or 92 mg Al/ per 2 hr, as a fume, each day for 9-13 months showed a significant retention of aluminium in the lungs of both groups of animals. The aluminium retention in the lungs in rats and hamsters exposed to fume was much greater than when exposed to powder. Following exposure to fresh air, aluminium oxide was cleared

Dolomite Mineral | Uses and Properties

(Powdered dolomite can easily be produced by scratching it on a streak plate.) Dolomite is very similar to the mineral calcite. Calcite is composed of calcium carbonate (CaCO 3), while dolomite is a calcium magnesium carbonate (CaMg(CO 3) 2). These two minerals are one of the most common pairs to present a mineral identifiion challenge in

Calcium hydroxide reacts in situ in aqueous media with silicon (e.g. magnesium sulfate, magnesium chloride) and aqueous alkali metal solution (sodium silie solution). In the reaction of

Reactivity Series Flashcards | Quizlet

One method of preventing rust is by covering Iron/Steel in a more reactive metal, such as Magnesium or Zinc. This more reactive metal with react with oxygen first, protecting the Iron or Steel below. The metal must be more reactive than Iron. It is called sacial protection, because the magnesium or zinc is saced to protect the iron.

Why is magnesium so reactive, compared to other …

As you see the table below magnesium has an electronegativity of 1.3 and zinc has an electronegativity of 1.7 where aluminum has an electronegativity of 1.6, the lower the electronegativity the more easily an atom loses electron that’s why magnesium is more reactive than zinc and aluminum, but magnesium is not the most reactive metal, cesium is.
