If the gas is oxygen, the oxide of the metal is most likely to form.
When metals react with bases, they often produce hydrogen gas and a salt. The metal displaces hydrogen from the base to form the salt, while hydrogen gas is released as a byproduct. This type of reaction is known as a displacement reaction.
Acids can react with metals to produce hydrogen gas, not oxygen. When acids react with metals, they displace hydrogen gas from the acid.
when metals react with acid hydrogen gas is liberated . and salt is formed eg; 2Na+2Hcl ------ 2Nacl+H2
Metals react with acids to produce a salt and hydrogen gas.
Metals such as zinc, aluminum, and iron can react with acids but not with water. When these metals react with acids, they undergo a chemical reaction that produces hydrogen gas and a salt. In contrast, these metals do not react with water to produce hydrogen gas.
A gas called hydrogen is given off when most metals react with aqueous hydrochloric acid. The ease with which this happens varies: All alkali metals reacts extemely quickly and, with the possible exception of lithium, dangerously. The alkaline earth metals, except beryllium and magnesium, are similar. Most other metals dissolve more slowly and may require heating to evolve the hydrogen gas, and some metals such as copper, gold, and platinum do not react at all.
When acids react with active metals, they always produce a salt and hydrogen gas.
Usually the two react to produce hydrogen gas and the corresponding metal sulfate.
No, not all metals react with hydrochloric acid to produce hydrogen gas. Only metals higher in the reactivity series than hydrogen, such as zinc, iron, and magnesium, will react with hydrochloric acid to form hydrogen gas. Metals like gold, silver, and platinum do not react with hydrochloric acid.
Oxygen
Formation of the metal chloride and hydrogen gas, depending on the metal of course. Not all metals will react.
Pure metals are neither, no pure element is and acid or an alkali, it is only compounds made from elements that have this property. When metals form compounds those compounds are typically alkaline.
