Write an equation for the reaction of: a) iron with steam …
When a metal reacts with water( cold water or hot water) then the products formed are metal hydroxide and hydrogen gas. Metal + steam -----> Metal hydroxide + Hydrogen Calcium reacts with cold water to form calcium hydroxide and hydrogen gas: Ca(s
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.
Ionic Reactions in Solution
When an acid reacts with a hydroxide, water and a salt are formed. All acids release hydrogen ions in solution. Hydroxides furnish hydroxide ions. Hydrogen ions and hydroxide ions react to form water, a covalent un-ionized molecule (see Figure 11.5b H + -H 2

Clan Labs Meth Sodium FS 10''29''03 - OEHHA
Sodium reacts violently with water, including moisture in the air, and dilute acids to form caustic NaOH and highly flammable hydrogen gas. The reaction generates considerable heat, melting the sodium and frequently igniting the hydrogen gas. Sodium reacts
Hydrogen (H) - Chemical properties, Health and …
Atomic hydrogen reacts with organic compounds to form a complex mixture of products; with etilene, C 2 H 4, for instance, the products are ethane, C 2 H 6, and butane, C 4 H 10. The heat released when the hydrogen atoms recoine to form the hydrogen molecules is used to obtain high temperatures in atomic hydrogen welding.
The Chemistry of Hydrogen - Purdue University
It forms compounds (such as HCl and HNO 3) that are analogs of alkali metal compounds (such as NaCl and KNO 3). Under conditions of very high pressure, it has the properties of a metal. (It has been argued, for example, that any hydrogen present at the center of the planet Jupiter is likely to be a metallic solid.)

Phosphide, any of a class of chemical compounds in which phosphorus is coined with a metal. The phosphide ion is P3−, and phosphides of almost every metal in the periodic table are known. They exhibit a wide variety of chemical and physical properties.
Zinc metal reacts with hydrochloric acid (HCl) to produce …
Now, when zinc metal reacts with hydrochloric acid, it leads to the production of zinc chloride salt and hydrogen gas. The equation follows: Here, zinc is more reactive metal than hydrogen because it lies above in the series.
