Are noble gases shiny?
No, noble gases are not shiny. They are colorless and odorless gases that do not have a metallic or reflective appearance.
What gases can you see?
You can see some halogen gases, such as Chlorine and Bromine and Iodine because they are coloured. Most other gases are colourless and cannot be seen.
How do psychical and chemical properties of halogens compare with those of the inert gas?
At room temperature the lighter halogens, F, Cl are diatomic gases, Br is a liquid, I is a solid. All of the halogens are colored and toxic. The noble gases are all colorless odorless non chemically toxic monoatomic gases. (Radon is radioactive).
Can helium and argon combine and form a substance?
No. Both are noble gases and do not combine with each other
Why are more people likely to be affected if the chemical is a gas rather than a liquid?
Gases are airbourne, whereas liquids are typically limited in how they travel by the path available and gravity. It's much easier to disperse a gas than a liquid, plus gases tend to be much less obvious - carbon monoxide, for instance, is a lethal gas which is both odourless and colourless. It depends what you mean by 'affected', drinking or injecting a toxic liquid might be far worse than breathing in a similar toxic gas. As mentioned above gases are airborne and are harder to contain.
What is colourless?
Lots of gases are colorless. You'd have to be more specific.
What gas is colourless?
Lots of gases are colorless. You'd have to be more specific.
When two e gases combine to make a liquid with differ when two gases form a liquid what happens?
science
When elements combine to form compounds their properties do not change.?
False. Hydrogen and oxygen - both gases - combine to form water - a liquid.
When elements combine to form a mixture their properties do not change?
They change their properties when they combine. Hydrogen and oxygen are gases but combine to form water, a liquid.
What colour is the air?
Almost all of the principal gases in the atmosphere are colourless. Hence we see the air as colourless.
Name colourless gases beginning with h?
hydrogen
Why cant oxygen be seen?
it is a colourless gas as are most gases
How is it possible for a liquid to be made of elements that are gases at room temperature?
elements can combine to form new substances with different properties.
Are noble gases shiny?
No, noble gases are not shiny. They are colorless and odorless gases that do not have a metallic or reflective appearance.
If the gas is hydrogen what would you see?
Hydrogen gas is odorless, colorless, and has no taste. A hydrogen flame is nearly invisible because it emits light in the (invisible) ultraviolet spectrum.
What is the odorless and colorless gas in a cigarette?
The colorless, odorless gases in cigarette smoke are:carbon monoxidecarbon dioxidewater vapournitrogen
