Why is always a cotton plug inserted at the end of a funnel during sublimation of ammmonium chloride?
sublimation means conversion of solid to direct gaseous state , if you didn't put cotton plug then your ammonium chloride's vapours will go to atmostphere and your ammonium chloride wasted. And if cotton plug is not applied you can't see conversion of it's vapours to solid again

When naming ionic bonds what does the anion always end in?
The anion in an ionic compound always ends in "-ide" when naming ionic bonds. For example, chloride (Cl-) in sodium chloride (NaCl) or oxide (O2-) in magnesium oxide (MgO).
What is the full name for SnCl2?
That is Tin (II) Chloride. Sn is Tin and the suffix for Chlorine is nearly always Chloride. The (II) means the Tin [in a hypothetical situation where the compound was purely ionic] has an oxidation state of 2, or +2, (ie deficient of two electrons) Source: A2 Chemistry Student.
Is alwayes sublimation point higher than melting point?
This question is unanswerable because anything that sublimes won't ever melt. Because sublime = the change from solid to gas, while at no point becoming a liquid. and melting = the process of heating a solid substance to a liquid I would beg to differ. Sublimation depends on other variables as well, i.e. pressure. (lower pressure) Water is a substance that sublimates and melts. It's sublimation point is actually lower than it's melting point (if it were higher the substance would be in it's transition state... defeating the purpose) I don't know nearly enough to tell you anything else, except that in a single substance, it is more likely that the sublimation point is lower.
Chemical formula for silver chloride?
Silver almost always has an oxidation state of 1+ and Chlorine an oxidation state of 1-. Therefore, silver chloride has a simple formula of AgCl.
What is the charge on a chloride ion in AICI3?
The charge on a chloride ion (Cl-) in AlCl3 is -1. This is because aluminum (Al) has a charge of +3, and since the compound is neutral overall, each chloride ion must carry a charge of -1 to balance the positive charge of the aluminum ion.
What is the ionic charge for chloride ions?
Chloride is always minus one (-1).
Should a needle be inserted with bevel up or down?
Always bevel up.
Should a needle be inserted bevel up or down?
Always bevel up.
What si the formula for aluminum chloride?
AlCl3 is Aluminum Chloride BUT it is highly deliquescent so you will almost always see it represented as AlCl3.(6H2O)
Why containers containing ammonium chloride should always be kept in closed containers?
Ammonium chloride is easily decomposed and NH3 and HCl are released.
If we heat a solid it ultimately changes into a liquid?
Not always. Some go straight from solid to gas eg dry ice ... called 'sublimation'.

What is the metal present in potassium chloride?
It's NOT the metal as such but positive ion of the metal: Potassium, the K+ ion together with the negative chloride ion: Cl- they form the salt potassium chloride: KCl You see, it's always in the name of the salt
What is the balanced equation for silver chloride?
AgCl It always has a valency of +1, though it is a transition metal
