A mixture of carbon monoxide and hydrogen is called:
Water gas.
Hydrogen gas.
Carbon monoxide gas.
None is correct.
In the reaction of hydrogen with chlorine, what initiation is usually required?
Light or heat.
Cooling to a very low temperature.
High pressure.
A catalyst like iron.
Which safety precaution is crucial when working with hydrogen gas in the lab?
Avoid open flames, as it is highly flammable.
Ensure good ventilation, as it is toxic.
Work in a dark room, as it is light-sensitive.
Wear gloves, as it is corrosive.
Why is concentrated sulfuric acid generally NOT used for the laboratory preparation of hydrogen gas with reactive metals?
It is too expensive.
It is highly corrosive.
It acts as an oxidizing agent, reacting with hydrogen to form water instead.
It reacts too slowly.
