What is the sodium chlorine molecule?
Sodium chloride is encountered as an ionic solid, with a giant ionic lattice structure, containing Na+ and Cl- ions. Sodium chloride in the solid state is not molecularIn sodium chloride vapour at high temperatures there are discrete NaCl diatomic molecules
Can sodium and mercury exist in monoatomic molecule in vapour state?
No, sodium and mercury exist as diatomic molecules in the vapour state due to the nature of their chemical bonding. Sodium forms Na2 while mercury forms Hg2 molecules.
Does iodine turn into vapour on heating?
Yes, iodine does sublimate directly from solid to vapor form when heated without turning into a liquid state. This is due to its relatively low melting point of 113.7°C.
Why must you use hot water bath to melt the naphthalene instead of heating it directly over a flame?
Using a hot water bath helps to heat the naphthalene gently and evenly, reducing the risk of overheating or burning the substance. Directly heating naphthalene over a flame can cause it to heat unevenly and result in combustion, which can release harmful gases and create a fire hazard.
What do we call substance which changes readily into vapour without heating?
A substance that changes readily into vapor without heating is called a volatile substance. Examples include alcohol and acetone.
How would one write out liquid water water vapor aqueous sodium chloride and solid sodium chloride in chemical equations?
Your question is not so clear; but: - liquid water - (H2O)l - water vapour- (H2O)g - sodium chloride as a solid - (NaCl)s

How Can you separate ammonium chloride from water?
by the process of sublimation the mixture of sodium chloride and ammonium chloride is placed in a dish and covered with an inverted funnel on heating, ammonium chloride will change into vapour,which will condense into a solid in the neck of the funnel ,whereas sodium chloride was left behind the dish
Is there a use for sodium?
Sodium is used for loads of things! Sodium Chloride is table salt, sodium metal is used to prepare elements to make alloys, and sodium vapour is used in street lights. It is also key in the paper, glass and textile industry. Hope this Helps!!
Will mercury vapour work in a sodium vapour fixture?
no
Why common salt cannot purified by sublimation?
Common salt, or sodium chloride, cannot be purified by sublimation because it has a high melting point (801°C) and does not sublime at normal temperatures and pressures. Sublimation is the process of a substance transitioning directly from a solid to a gas without passing through the liquid phase, which is not applicable to sodium chloride.
Sodium chloride can be recovered from sea water by three methods evaporation simple distillation and crystallization which method will yield pure form of sodium chloride?
You cannot get salt from sea-water using distillation - all 3 methods you mention are effectively the same thing - all are just removal of water as vapour.
What type of intermolecular force in NaCl?
Dipole-dipole forces, as Na is positive, however Cl is negative. They cross each other out, but when coming into contact with other molecules, Na, the positive, attracts the Cl of the other molecule, which is the negative part, and so on.
When sodium bicarbonate is heated what will it release?
water vapour
Which metal vapour is used in fog lamps?
Probably sodium.
Do you have sodium chloride molecule?
In the crystalline state, sodium chloride consists of sodium cations (Na+) and chloride anions (Cl-) in a regular structure in which each Na+ is surrounded by six Cl- and vice versa, so that the whole thing is electrically neutral. In the crystalline state, there are no covalently bonded 'NaCl molecules'. Similarly, when salt is dissolved in water, the ionic crystalline structure breaks down and the individual ions are surrounded by water molecules.The interesting aspect to the question is what is the state of play in the gas phase. Astronomers are interested in this because, recently, sodium chloride has been detected in space above Saturn's moon Enceladus, and they refer to the presence of 'sodium chloride molecules'. Most chemists would disagree with this, preferring instead to talk about discrete 'ion pairs' ie Na+Cl- which are known to exist in the vapour phase. Talking about 'sodium chloride molecules' implies the existence of covalent bonding (ie electron sharing) between the sodium and chlorine atoms, and this is thought to be very improbable in the chemistry of these elements.
Which is the metal vapours used in yellow street lights?
Sodium vapour.
