What else can I help you with?
What are two gases that are unlikely to react with steel?
Argon and Helium. Being inert gasses, they do not react with anything.
What are two noble gases that doesn't reacts with anything?
That should be the first two noble gases: Helium and Neon. These two are chemically inert and do not react with anything.
Why are He and Ne called noble gases?
They do not react very much with anything (their outer electron shells are full)
What can form a mixture?
A mixture is formed from substances which doesn't react.
Which group is non-reactive (inert)?
In chemistry the Inert Group are the Noble Gases. So called be cause they do not react with anything. The gases are Helium, Neon, Argon, Krypton, Xenon, Radon.
Gases will react with the ozone layer and break it down?
CFC's are the gases that react with ozone to break it down. They deplete the ozone.
Uranium doesn't react with what?
Uranium doesn't react with noble gases.
Which gas does not react with oxygen?
Noble gases are considered inactive and do not react with any other substance/element.
Why does neon not have any compounds?
This is basic AS chemistry. Neon is in the group of the periodic table known as the noble gases. These elements are inert which means they don't react. Therefore neon does not have any compounds as it is unable to react with anything.
What happens when gases mix with metals?
At a given temperature gases can react with metals.
2 or more combined substance that do not react?
Noble gases do not react with each other like Xenon and Helium will not react
Why are noble gases are among the last of the naturally occurring elements to be discovered?
Because they don't react with anything else; when you're looking for reactions, noble gasses are invisible.
