Hydrogen. You can test it by putting a burning splint over the test tube, it should pop. I'm not sure if this is true most of the time, but it is true for many metals.
Hydrogen
A metal that does not react to acid, oxygen or water does not exist.
metals which dont react with water or acid are called unreactive metals
If a gas is produced it is hydrogen (H2)2H+(from acid) + 2e-(from metal) --> H2
When metals react with dilute hydrochloric acid, hydrogen gas is produced. This is because the metal atoms displace hydrogen atoms from the acid, forming metal chloride and releasing hydrogen gas as a byproduct.
yes
Metals that react well with water: Sodium - fizzes Potassium - burns Caesium - explodes Metals that react well with acids: Magnesium
Nitric acid reacts strongly with many metals.
When acids react with some metals, they produce hydrogen gas and a salt of the metal. The metal replaces hydrogen in the acid to form a salt, while hydrogen gas is released as a byproduct of the reaction. This process is known as a single displacement reaction or a metal-acid reaction.
No, not all metals react with hydrochloric acid. Generally, metals that are more reactive than hydrogen in the reactivity series will react with hydrochloric acid to form metal chloride and hydrogen gas. Metals which are less reactive than hydrogen, such as copper, silver, and gold, do not react with hydrochloric acid.
When dilute acids react with metals, hydrogen gas is typically produced. This is due to the displacement of hydrogen ions in the acid by the metal atoms, resulting in the formation of hydrogen gas bubbles.
Reactive metals like sodium, potassium, and magnesium react quickly with water to produce hydrogen gas. Strong acids like hydrochloric acid and sulfuric acid also react quickly with metals to produce metal salts and hydrogen gas.
