calcium metal reacts with oxygen gas formula

Calcium - Wikipedia

2019-5-6 · The chemistry of calcium is that of a typical heavy alkaline earth metal. For example, calcium spontaneously reacts with water more quickly than magnesium and less quickly than strontium to produce calcium hydroxide and hydrogen gas. It also reacts with the oxygen and nitrogen in the air to form a mixture of calcium oxide and calcium nitride.

Coination Reactions

2012-12-26 · Oxygen and the halogens are very reactive elements and are likely to undergo coination reactions with other elements. When a metal undergos a coination reaction with oxygen, a metal oxide is formed (similarily, a metal halide is formed if reacted with one of the halogens). You see the products of this type of reaction whenever you see rust.

2018-4-8 · Example 1. Question: Rubidium metal reacts rapidly with oxygen gas from the atmosphere at room temperature. Is rubidium a very active metal, a moderately active metal or a noble (inactive) metal? Response: The more active a metal is, the more readily it reacts with oxygen. Rubidium, like potassium, reacts rapidly with O 2(g), so rubidium, like potassium, is a very active metal.

Calcium oxide - Wikipedia

2019-5-6 · Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound.It is a white, caustic, alkaline, crystalline solid at room temperature. The broadly used term lime connotes calcium-containing inorganic materials, in which carbonates, oxides and hydroxides of calcium, silicon, magnesium, aluminium, and iron predominate.
