Powdered magnesium oxide was added in 0.1 g amounts to 25 cm3 of dilute hydrochloric acid and the mixture stirred. The powder soon reacted and disappeared, but after about 1.0 g had been added it took some time for all the solid to react. When a total of 1.1 g
Sodium in Water Chemistry Demonstration - ThoughtCo
28/10/2019· The sodium in water chemistry demonstration is a spectacular demonstration that illustrates the reactivity of an alkali metal with water. A small piece of sodium metal will be placed in a bowl of water. If a phenolphthalein indior has been added to the water, the sodium will leave a pink trail behind it as the metal sputters and reacts.
The metal has a silvery color, is rather hard, and is prepared by electrolysis of the fused chloride to which calcium fluoride is added to lower the melting point. Chemically it is one of the alkaline earth elements; it readily forms a white coating of nitride in air, reacts with water, burns with a yellow-red flame, forming largely the nitride.
Lithium Overview Toward New Technologies for the Production of …
acts with water (and moisture in the air) to produce the hydroxide, LiOH, and hydrogen gas. Unlike the heavier alka-lis, lithium does not react violently with oxygen; indeed, the metal is stable in dry air when the dew point is maintained below –38 C. Lithium is not

Ans. Sodium is highly reactive metal. It reacts with oxygen in air at room temperature, the reaction is highly exothermic. To prevent this sodium is kept preserved under kerosene. Ans. Zinc is more reactive than iron, hence when added‘ to iron (II) sulphate, it can displace iron metaliand the colour of solution fades from green to colourless due to formation of zinc sulphate.

Water purifiion - Wikipedia
Water purifiion is the process of removing undesirable chemicals, biological contaminants, suspended solids, and gases from water. The goal is to produce water fit for specific purposes. Most water is purified and disinfected for human consumption (drinking water), but water purifiion may also be carried out for a variety of other purposes, including medical, pharmacological, chemical

This water spray also adds water to the reaction chaer to keep the reaction going as new calcium carbide is added. After the gas is cooled, it passes through a flash arrester, which prevents any accidental ignition from equipment downstream of the chaer.
Steel - Wikipedia
Steel is an alloy of iron with typically a few percent of carbon to improve its strength and fracture resistance compared to iron. Many other additional elements may be present or added. Stainless steels that are corrosion and oxidation resistant need typically an additional 11% chromium..
How to Mix Calcium Chloride and Water | Sciencing
Calcium chloride is a chemical compound made up of calcium ions and chlorine ions. The ions are held together by an ionic, or weak salt bond. Mixing calcium chloride with water is an exothermic reaction, which means that the coination of the two substances
