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 the colour of the fumes given off when crystals of iodine are heated?
The fumes given off when crystals of iodine are heated are purple in color.
What process causes iodine vapor to collect in a flask of solid iodine?
Sublimation is the process where solid iodine directly turns into iodine vapor without passing through the liquid phase. When the solid iodine is heated, it sublimes into vapor which then collects in the flask as the vapor cools down and condenses.
Why does solid iodine change when its heated?
Solid iodine is transformed by heating in a liquid at 113,7 oC.
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.
Why is iodine heated gently?
Because it sublimes that is it directly forms into a solid
What is shiny black solid but gives off a purple vapor when heated.?
You think to iodine.
Why iodine vaporize when heated gently?
Iodine vaporizes when heated gently because of sublimation, where the solid iodine directly transforms into iodine vapor without passing through a liquid phase. This occurs due to the weak intermolecular forces between iodine molecules, allowing them to escape from the solid crystal lattice and form a gas.
Why does solid iodine only stick to fingerprints when they are heated?
because when they are heated they are sticky and they only fix to fingers
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 black solid forms a purple vapour when heated gently?
Iodine is a black solid that sublimes directly to a purple vapor without passing through a liquid phase when heated gently.
What element sublimes when gently heated?
Iodine is an element that sublimes when gently heated. Sublimation is the process of a substance transitioning directly from a solid to a gas phase without passing through the liquid phase.
