Several gasses can react with metals, but due to the fact that you are asking for a single gas, the most likely answer that you will be looking for is Oxygen. Oxygen reacts with many metals (and non-metals).
Acids react with metals. Metals are themselves basic in nature. Metals displaces hydrogen from acids to liberate hydrogen gas.
When mixed with certain metals, a hydrogen gas is produced.
Because they are able to dissolve and are more reactive than hydrogen
Hydrogen. The same is true for when most metals react with an acid.
A salt and hydrogen gas is produced. Effervesence can be observed.
Many metals react with strong acids to produce hydrogen gas.
Fluorine gas is one of the most reactive elements that exist and it will react with most metals.
Acids react with metals. Metals are themselves basic in nature. Metals displaces hydrogen from acids to liberate hydrogen gas.
HCl is an strong acid, gas, reacts with metals NaCl is a neutral salt, crystalline solid, stable to most metals,
I am assuming you are mixing Magnesium and Zinc metals with an acid which would produce Hydrogen gas.
When mixed with certain metals, a hydrogen gas is produced.
Because they are able to dissolve and are more reactive than hydrogen
Hydrogen. The same is true for when most metals react with an acid.
hydrogen gas is liberated when an acid reacts with a metal.The equation is as follows acid + metal=salt + h2
A salt and hydrogen gas is produced. Effervesence can be observed.
All the other alkali metals (sodium, potassium, rubidium, and cesium) reacts with water with increasing violence. Some of the alkaline earth metals (calcium, strontium, and barium) and a few other metals (such as europium) react in similar manner to produce hydrogen gas and the corresponding metal hydroxide.
Nitrogen, is the most reactive gas that can be found abundantly in the air...
