Why hydrogen gas is not liberated when metals react with nitric acid?
Nitric acid is a strong oxidizing agent that can oxidize hydrogen gas to water instead of being reduced itself to release hydrogen gas. As a result, metals do not liberate hydrogen gas when they react with nitric acid.
Why hydrogen is liberated when magnesium react with dilute nitric acid unlike other metals where hydrogen is not evolved?
Magnesium reacts with dilute nitric acid to form magnesium nitrate and liberate hydrogen gas because magnesium is a highly reactive metal and is able to displace hydrogen from nitric acid. Other less reactive metals do not typically react with dilute nitric acid to produce hydrogen gas.
Why is nitric acid in the dilute form not used in the laboratory preparation of hydrogen from metals?
It is because nitric acid is a strong oxidising agent (because it decomposes to yield nascent oxygen as:2HNO3 →2NO2 + H2O + [O])and it oxidises the hydrogen formed to water.Only 1% dilute and cold nitric acid reacts with magnesium and manganese to liberate Hydrogen gas.
Why hydrogen is not evolved when a metal react with nitric acid?
Nitric acid is a strong oxidizing agent and its molecule is unstable as compare to nitrogen oxides, on reacting with metals it gives hydrogen and oxygen both so water is produced instead of hydrogen.
Why most metal do not displace hydrogen from nitric acid?
Most metals do not displace hydrogen from nitric acid because nitric acid is a strong oxidizing agent that prefers to undergo reduction itself rather than allow the metal to displace hydrogen. Nitric acid can oxidize the metal directly, forming metal ions and nitrogen oxides, instead of being displaced by the metal to form hydrogen gas.
Write the names of any two metals which can liberate hydrogen gas from nitric acid?
Sodium and potassium

Does hydrogen gas liberate when metals react with carbonic acid?
By definition metals above hydrogen should react with acids to produce hydrogen and a metal salt when mixed, but carbonic acid is a weak acid and it won't react as much like sulfuric acid.
Name some acids that react with metals?
Nitric acid reacts strongly with many metals.

Why metals except Mg and Mn do not form hydrogen when they react with nitric acid?
The question needs an opposite answer:Most metals, except some noble ones like Pt, Au and maybe Hg or Ag, can NOT resist the oxidation power of nitric acid. This is because of the high oxidation power (potential) of nitric acid (even dilute acid is very potent).
Why Cu does not liberate H2 gas from dilH2So4?
Copper (Cu) is below hydrogen (H) in the activity series of metals, which means it is less reactive than hydrogen. As a result, when copper is placed in dilute sulfuric acid (H2SO4), it is unable to displace hydrogen from the acid to liberate H2 gas. Only metals above hydrogen in the activity series can displace hydrogen from acids to form hydrogen gas.
Elements in nitric acid?
Nitric acid contains hydrogen, nitrogen, and oxygen. It has the formula HNO3.
Which 2 metals can displace hydrogen from dilute nitric acid?
magnesium and manganese Mg(s) + 2 HNO3(aq) → Mg(NO3)2(aq) + H2(g)
