The Reactivity Series is a way of organising metals in a table in …
The more reactive a metal, the greater tendency it has to form a positive ion during a reaction (e.g. Na becomes Na+, or Fe becomes Fe2+). This is linked to whether a metal reacts or not. Copper does not react with water or hydrochloric acid, and therefore
Some oxides of period 3, such as Na 2 O and P 4 O 10, react with water.A spatula measure of each oxide was added to a separate 100 cm 3 flask containing distilled water and a few drops of bromothymol blue indior. The indior is listed in section 22 of the

2nd pg. - The Element Calcium
Calcium metal was not available in a large scale until the beginning of the 20th century. Calcium oxide (CaO) is a white solid rock and is made by heating calcium carbonate (CaCO3) at high temperatures. This is the chemical equation: CaCo3 -> Co2 + Cao.

Alkali hydroxide - Wikipedia
A vigorous reaction occurs, producing hydrogen gas and the specific alkali hydroxide. For example, if sodium is the alkali metal: Sodium + water → sodium hydroxide + hydrogen gas 2 Na + 2 H 2 O → 2 NaOH + H 2 Properties of Alkali Metal hydroxides
Calcium metal stored in an argon atmosphere. Why do some chemical reactions occur readily while others require input of heat in order to take place? If we mix metallic sodium with water , a reaction occurs immediately, releasing a great deal of heat (enough to ignite the hydrogen gas that is formed).
