What else can I help you with?
What gas is produced when iodine are heated?
When iodine is heated, it sublimes directly from a solid to a purple gas. The gas produced is diatomic iodine molecules (I2).
What is a solid purple-black non metal which changes to a deep purple gas when heated?
Iodine is a purple-black non metal that changes to a deep purple gas when heated.
What element is in a violet gas form?
The element present in a violet gas form is iodine. When iodine is heated, it sublimes directly from a solid to a gas, producing a distinctive violet vapor.
Why can gas iodine stick to fingerprints?
The gas iodine will stick to the fingerprints because they will crystallize when they come into contact with a cool surface. When heated, iodine directly changes into vapor.
What is the purple gas which fills the test tube when heating an iodine?
The purple gas formed when heating solid iodine in a test tube is iodine vapor. Iodine sublimes directly from a solid to a gas when heated, turning into a purple gas that condenses back into solid iodine crystals when cooled.
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?
The purple gas that forms when heating iodine crystals is called iodine vapor.
What state is the iodine in when it is heated?
When iodine is heated, it sublimes from a solid state directly into a purple-colored gas. It undergoes sublimation, which means it changes from a solid to a gas without passing through the liquid state.
What ductility of iodine?
Iodine is a brittle solid at room temperature and does not exhibit ductility. It easily sublimes into a gas when heated.
What do you call the purple gas that fills the test tube when a few crystal of iodine is being heated inside a test tube?
This is also iodine, as a gas.
How does iodine turn into a gas?
Iodine turns into a gas through the process of sublimation, where it changes from a solid directly into a gas without passing through the liquid phase. When heated, iodine sublimes and forms violet vapor that can be observed as a gas.
Is iodine a solid lidquid or gas?
Iodine is a solid at room temperature and pressure. It sublimes directly from a solid to a gas when heated without passing through a liquid phase.
When iodine crystals are heated and cooled in a hot water bath what happens?
When iodine crystals are heated, they sublimate directly from solid to gas without melting. As the hot iodine gas cools, it reverts back to solid form on the cooler surfaces of the container, forming iodine crystals again. This process is called sublimation.
