Iodine is a purple-black non metal that changes to a deep purple gas when heated.
When iodinebecome to purple gas describe chemical properties?
Iodine sublimes into a purple gas without passing through a liquid phase. This is a change in physical state, which is a physical change.
What is formed when water and iodine crystals and aluminium powder is combined?
it reacts and makes aluminum iodide and hydrogen iodide (purple smoke)
Kaitlyn was getting ready to study a purple gas in the laboratory before beginning her experiment she remembered to measure the total volume of the flask that would contain the gas she should also?
measure the weight of the flask and take care not to breathe in any of the purple gas (could be iodine vapour).
What are some characteristics of iodine?
iodine is a shiny, black silver metal and sometimes a purple liquid
What is a solid purple-black non metal which changes to a deep purple gas when heated?

What do you call the purple gas that fills the test tube when a few crystals of iodine is being heated inside a test tube?
This is also iodine, as a gas.

This is also iodine, as a gas.
Why does iodine emit a purple gas when heated?
Because iodine sublimates, as do the other solid halogens. That means they go from solid to gas without becoming a liquid first.
When iodine is heated does any iodine melt?
iodine is a substance that has an unusual property, it has the ability to sublimate, this means that it converts directly from a solid to a gas with no liquid stage at all. So no, no iodine will "melt" into a liquid, it will insted turn into a purple gas.
What gas is produced when iodine are heated?
Gas of diatomic iodine I2 .
Is chemical change a black solid when heated changes into a purple gas?
When it is iodine (I2) it is only physical sublimation of the black (metallic shiny) I2 crystals into purple heavy gas clouds or fumes
These dark crystals turn into a purple vapour when heated?
Iodine
What element is is shiny black solid but gives off a purple vapor when heated?
Iodine on heating gives off dense purple vapor.
What is the purple gas which fills the test tube when heating an iodine?
It is also iodine, as a gas.
