Sodium, Chemical Element - reaction, water, uses, …

Sodium also reacts with most other elements and with many compounds. It reacts with acids to produce hydrogen gas. It also dissolves in mercury to form a sodium amalgam. An amalgam is an alloy of mercury and at least one other metal.

Hydrogen iodide - Wikipedia

Hydrogen iodide (HI) is a diatomic molecule and hydrogen halide. Aqueous solutions of HI are known as hydroiodic acid or hydriodic acid, a strong acid. Hydrogen iodide and hydroiodic acid are, however, different in that the former is a gas under standard conditions, whereas the other is an aqueous solution of the gas. They are interconvertible

Factors Affecting Reaction Rates | Chemistry

The active metals calcium and sodium both react with water to form hydrogen gas and a base. Yet calcium reacts at a moderate rate, whereas sodium reacts so rapidly that the reaction is almost explosive. The State of Subdivision of the Reactants

An Introduction to Calcium Metal - MMTA

2016/4/13· Calcium is, however, a metal in its pure form, though rarely seen in this state due to its instability. In air, calcium decomposes rapidly into calcium hydroxide and calcium carbonate. Calcium carbonate is the chalky substance we associate with calcium, with the white cliffs of Dover (see right) being composed of this compound.

WebElements Periodic Table » Calcium » reactions of …

Once ignited, calcium metal burns in air to give a mixture of white calcium oxide, CaO, and calcium nitride, Ca 3 N 2. Calcium oxide is more normally made by heating calcium carbonate. Calcium, immediately below magnesium in the periodic table is more reactive with air than magnesium.

Calcium oxide reacts with water to produce calcium …

When you visit a website, you are of course observable by the site itself, but you are also observable by third-party trackers that the site eeds in its code. You might be surprised to learn that the vast majority of websites include many of these third-party trackers.

Magnesium Chloride: Source of Magnesium for Alloys

Alloys are produced by coining a pure metal with one or more other elements to form a new substance with desirable properties. (Steel, for example, is a common alloy of iron and carbon.) Magnesium alloys are found in aircraft, automobiles, rockets, luggage frames, portable power tools, cameras, laptop computer casings and mobile phones.

Iron - Simple English Wikipedia, the free encyclopedia

Iron is a chemical element and a metal. It is the most common chemical element on Earth (by mass), and the most widely used metal. It makes up much of the Earth''s core, and is the fourth most common element in the Earth''s crust. The metal is used a lot because it is strong and cheap. Iron is the main ingredient used to make steel. Raw iron is

Reactions of the Group 2 elements with air or oxygen

2020/8/8· This page looks at the reactions of the Group 2 elements - beryllium, magnesium, calcium, strontium and barium - with air or oxygen. It explains why it is difficult to observe many tidy patterns. On the whole, the metals burn in oxygen to form a simple metal oxide. Beryllium is reluctant to burn
