Hydrogen Production Technologies: Current State and …
Hydrogen (H2) is currently used mainly in the chemical industry for the production of ammonia and methanol. Nevertheless, in the near future, hydrogen is expected to become a significant fuel that will largely contribute to the quality of atmospheric air. Hydrogen as a chemical element (H) is the most widespread one on the earth and as molecular dihydrogen (H2) can be

Why dont metals react with HNO3 to liberate hydrogen …
Dear folk!! Any metal above hydrogen in the activity series will react with dilute HNO3 to produce hydrogen gas and the oxidized form of the metal in solution. If the HNO3 is very concentrated (above 8 or 10 molar), then NO gas is produced. NO gas quickly oxidizes

Francium is very scarce and expensive. It is umlikely that anyone has ever reacted the metal with water. However, given that all the other Group 1 elements react to form colourless basic solutions of the hydroxide and hydrogen gas (H 2), it would be strange were
To Study the Relative Reactivity of Metals using Salt …
The most reactive metals will react even water, while the least reactive metals will not react even with acid. Example: If we put a small piece of sodium metal in water, sodium reacts exothermically with water producing hydrogen and metal hydroxide.

Air Products has been fueling buses with hydrogen for over 20 years and recently installed a 1,000 kg/day hydrogen bus fueling station in Asia, as well as a 200kg/day station in Europe. Air Products has also been involved with bus projects with Transport for London, and with SARTA in Canton, Ohio.
IGCSE Study Guides, Revision & Notes: Metals
Some metals such as potassium and sodium are so reactive they will react vigorously with cold water to form metal hydroxides and hydrogen gas. For the moderately reactive metals they will only react with steam to produce the appropriate oxide and hydrogen gas.

If 6.57 g of iron react with an excess of hydrochloric acid, HCl, then 11.2 g of iron(II) chloride are obtained in addition to hydrogen gas. Find the theoretical and percent yields.
What happens when calcium is treated with water?(i) It …
In general, metals form a metal oxide and hydrogen gas and this metal oxide when soluble in water dissolve further forming a metal hydroxide. But some metals form metal hydroxide directly. In the case of calcium, the reaction with water is less violent and hydrogen starts floating on water and bubbles of hydrogen gas will stick to the metal surface.

Chemical Properties of Metals
Metals react with water to produce metal oxide (or metal hydroxide) and hydrogen gas. But, all metals do not react with water at equal intensity. The metals which are very reactive can react even with cold water while the other metals react with hot water or with steam.
