What colour is cyanide gas or vapour?
Hydrogen cyanide is colorless.
Gaseous propane is colorless.
Water vapor is a gas. Therefore it can not be seen it is invisible. It is a greenhouse gas that is in the Earth's atmosphere.
when iodine crysatals are heated, they turn from a solid into a gas (vapour). They start a black colour and as they gradually turn into a gas, they turn to a purple colour. At the end, there are no crystals left.
It is recommended to use a hydrogen cyanide gas detector.
As the word "vapour" indicates, it is a gas.
sodium cyanide, hydrogen cyanide gas, etc.
Add an acid and it will release cyanide gas.
Silver nitrate and Hydrogen cyanide. Hydrogen cyanide is the gas used for execution by gas chamber, so not a reaction to try at home.
No, the Holocaust gas was not a nerve agent. It was a cyanide gas. Cyanide kills by binding to the blood in your system, rendering it useless to you.
Each gas has a specific density at a given temperature and pressure. The expression "vapour density of gas" is not correct.
The gas and vapour expand because when heating the physical properties of gas and vapour change and it expanded
Produce hydrogen cyanide, a toxic gas.
astatine is a very dark pink colour, the vapour is purple.
yes beacause it is vapor ......
cyclon b or hydrogen cyanide
Vapour and gas are not same.A substance which under ordinary conditions is a solid or a liquid,but under specific conditions is gaseous is called a vapour. For example,water vapour,sulphur vapour,etc. However, a substance which under ordinary conditions is gaseous ,is called a gas. for example,Oxygen,Nitrogen,etc
A vapour is a gas.
i think it is gas gas it is
It is called water vapour or simply vapour.
cyanide tablets turned into gas
well they dont actually use a sepific type of gas for the gas chambers. they put acid then put cyanide in the gas chamber. this will create a chemical reaction and hydrogen cyanide gas is made, which slowly kills the victim in the gas chamber.
Water vapour is a gas and invisible. Cloud water droplets are what appear when water vapour condenses (they are either liquid droplets or suspended ice cristals: not gas). Therefore, you can see clouds but not water vapour.
Water Vapour is a colourless, odourless gas which is made of tiny water droplets.
Hydrogen cyanide HCN
according to electronic spectra I2 in gas phase is violet due to promotion of electron from 4pi* to 9sigma* while its absorbing 500 nm.
Water vapour is a gas.
Bromine gives off a red vapour.
pi* to sigma* transition
Hydrogen cyanide and carbon monoxide.
Hydrogen cyanide, Zyclon-B.
Yes it is a matter, water vapour is a form of gas, as matter consists of three states, solids, liquids and gas. So water vapour IS a form of matter. Written by Brigitte.P age 13
no it is a gas when it is a vapour
It is not a vapor. It is a gas normally.
A gas is the normal state for a material at given temperature while a vapour is made from some particles that have escaped from the liquid surface.
Condensation is where a vapour (gas) is cooled, and droplets of liquid form. Vapourisation is where a liquid is heated, and the liquid turns into vapour (gas).
A gas - since a vapor is but a gas close to its condensation point.
The gas in the line contains a proportion of water vapour (which is also a gas). When the gasses in the line cool below the dew point for the gas water vapour mixture, water condenses out of the gasses inside the gas pipe.
It is often called vapor, or vapour.
When water is in the form of a gas, it is called water vapour.
A gas called water vapour is formed, it is steam.
A mist is a gas. It is not a solid or a liquid. An example of a solid would be a rock, of a liquid would be water and of gas would be steam. Other examples of are gas: steam vapor/vapour (water vapour)
cyanide --- probably hydrogen cyanide gas supposedly smells like almonds.
a pure gas of oxygen and hydrogen The water cycle is driven by the Sun's energy. When water evaporates, it turns into the invisible gas called water vapour.
Carbon monoxide (CO) interferes with gas transfer in the blood. Cyanide (HCN) also blocks gas mechanisms resulting in death from hypoxia.
Hydrogen cyanide in a base called Zyklon B.
A green colour, water vapour and, (during the daylight), oxygen.
they turn from gas to liquid
