No. Generally all acids are liquid or aqueous.
When sulphuric acid is added to zinc granules , the gas produced is hydrogen gas. Zinc displaces hydrogen from sulphuric acid.
sulphuric acid
When potassium nitrate crystals are heated with concentrated sulphuric acid, nitric oxide gas (NO) is evolved. This is a result of the oxidation of nitrate ions in potassium nitrate by the sulphuric acid.
Sulfur Dioxide (a gas) evaporates into the atmosphere, mixes with precipitation (rain), and falls to earth as sulphuric acid.
when you mix sulphuric acid with magnesium you create a gas called hydrogen.
Sulphuric acid
Nickel forms Hydrogen gas when reacts with dilute acid.
the h2 ions and the so4 ions in the sulphuric acid help electricity pass through it. this makes it a strong electrolyte.(electrolyte- a liquid which conducts electricity)
NO!
ozone
hydrogen gas and zinc sulphate
The valency for sulphuric acid is H2SO4
