What else can I help you with?
Can sulfur sublime?
Yes, it is possible at temperatures between 25 0C and 50 0C. Besides substances such as naphthalene, ammonium chloride, iodine, dry ice, camphor and anthracene, sulphur also sublimes.
How do you separate a mixture of potassium chloride and iodine give details?
To separate a mixture of potassium chloride and iodine, you can use a process called sublimation. Iodine can be sublimed by heating the mixture, causing it to change from a solid directly to a gas. The iodine vapor can then be collected and condensed back into solid iodine. The remaining potassium chloride will be left behind as a solid.
What is the obtained form of iodine?
Iodine (I), sodium iodide (NaI), potassium iodide (KI), hydroiodic acid (HI)
How do you separate ammonium chloride from salt?
You can separate ammonium chloride from salt by sublimation. Ammonium chloride sublimes at a lower temperature compared to salt, so when heat is applied, ammonium chloride will turn directly into a gas and can be collected as a solid again by cooling it down. Salt will remain behind as a residue.
If ammonium chloride and sand under goes sublimationwhich solid sublimes?
Ammonium chloride sublimes when heated, transitioning from a solid directly to a gas without passing through a liquid phase. Sand does not undergo sublimation as it does not turn into a gas when heated, but rather melts at high temperatures.
By which process can you separate a mixture of naphthalene and chalk powder?
Sublimation can be used to separate naphthalene from chalk powder. Naphthalene sublimes at room temperature, while chalk powder does not, allowing for the separation based on this difference in physical properties.
Can iodine and naphthalene be separated by sublimation?
Yes, iodine and naphthalene can be separated by sublimation because they have different sublimation points. Iodine sublimes at a lower temperature compared to naphthalene, allowing for the selective separation of the two substances based on their sublimation properties.
Why mothballs turn small?
Mothballs turn small because they are made of a volatile chemical compound, such as naphthalene or paradichlorobenzene, that sublimes into a gas at room temperature. As the compound sublimes, it changes from a solid state directly to a gas, causing the mothballs to shrink over time.
What else skips its 2nd state of matter besides dryi ice?
solid iodine, paradichlorobenzene, naphthalene, and many solid organic substances. Regular ice also sublimes if the tempeature is low enough.
How can naphthalene be separated from a mixture of naphthalene and common salt.explain?
Naphthalene can be separated from common salt by sublimation since naphthalene sublimes at a lower temperature than common salt. By heating the mixture, naphthalene will turn directly from a solid to a gas, leaving behind the common salt as a solid residue. The naphthalene gas can then be cooled and collected back as a solid.
What are examples of substances that changes to solid from gas?
That is a substance that sublimes. It is not common. Naphthalene (old-fashioned moth balls), also carbon dioxide (dry ice)
What happens to naphthalene when it sublimes?
When naphthalene sublimes, it transitions directly from a solid to a gas phase without passing through a liquid phase. This process occurs when the substance is heated and the vapor pressure exceeds the atmospheric pressure. As the naphthalene molecules gain enough energy to break free from the solid phase, they transform into a gas.
What solid sublimes on heating?
Some solids are Carbon dioxide, Snow, Iodine and Naphthalene
Why nephtaline sublimes?
Naphthalene sublimes due to its relatively low melting and boiling points, allowing it to transition directly from a solid to a gas when heated. This process occurs because the intermolecular forces in naphthalene are weak enough to let the molecules escape into the vapor phase without first becoming a liquid. Sublimation is facilitated at room temperature, which is why naphthalene is often found in mothballs, where it gradually releases vapor to repel insects.
Why does the size of naphthalene balls reduce if it is kept in open?
because it sublimes in the air. in easier language it dissolved n air easily
Does naphthalene decompose when gently heated?
Yes, naphthalene sublimes and undergoes vaporization at temperatures above 80 degrees Celsius rather than decomposing directly. At temperatures exceeding its sublimation point, naphthalene converts from a solid to a gas without passing through a liquid phase.
Why do napthalene balls kept in woollens disappear on their own after one season?
Naphthalene sublimes over time. That means it turns into vapour which disappears into the air.
