The observation that hydrogen chloride is a gas at room temperature is a PHYSICAL property.
"This gas" is hydrogen, correct? The property that contributed to the Hindenburg Disaster is flammability.
1.Action with litmus
Flammability. Hydrogen will burn (combust, oxidize) in oxygen, producing heat and water.
chemical
the react with metals to release hydrogen gas
it is is one of the property of hydrogen as it is highly inflammable gas ever known . it is also used in hydrogen bombs.
it is chemical change
Hydrogen, helium and oxygen are gases. Gravity is a physical property of any substance.
No, the gas produced is a result of the chemical reaction.
hydrogen and hydrogen gas are same hydrogen is gas
No, a metal reacting with an acid is a chemical change, and its ability to do so is a chemical property.
