how much does the element chlorine cost?

You can't buy elemental chlorine, you'll never find, chlorine is found as a diatomic molecular gas (Cl2) and since this is a homework problem, here are some websites you can go to find out, \n\n\nwww.aldrich.com\nwww.chemfinder.com (type in cl2 then click on the purchase button)\nor google it

$2.98 per 9/10 gal. So Cal.

Write down the equation of reaction: K + Cl2 -> KCl (not balanced)\n\nBalance the equation of reaction: 2K + Cl2 -> 2KCl (balanced)\n\nFind the moles of Potassium: 5 g K / 39.10 g/mol K = 0.128 mol\n\nFind the moles of Chlorine gas: 7 g Cl2 / (2 x 35.45 g/mol) = 0.098 mol\n\nDetermine the stoichiometric ratios: \nCl2 -> 2 KCl\nK ->   KCl   \n\nFind the moles of product: \n\nFor potassium: 0.128 mol K x (1 mol KCl / 1 mol K) = 0.128 mol KCl\n\nFor chlorine:  0.098 mol Cl2 x (2 mol KCl / 1 mol Cl2) = 0.196 mol KCl\n\nSo potassium is the limiting reactant. \n\nMass of KCl that can be formed: 0.128 mol K x (1 mol KCl / 1 mol K) x (39.10 g/mol K +  35.45 g/mol Cl) =  9.54 g KCl

Chloride prevents bacteria and other organisms from growing in water, though it does have a chemical taste that some find unpleasant.  Otherwise in relatively low concentrations it is not harmful to health, and in fact chlorine is an essential electrolyte.  \n\nChlorine gas is of course, poisonous, but that's mostly because it is corrosive.

sodium is 23g per mol, chlorine is 35g per mol and 2.5 liters of 2 molar sodium chloride has 5 mols sodium chloride, which has a molar mass of 58 grams, therefore the mass of sodium chloride is 290g(depends on number of significant figures)

The answers are KCl, CaF2, and Na2O. Potassium has one electron on the outer ring while chlorine has seven. To make chlorine's ring "full" potassium gives the one electron to chlorine. They are "happy" now. :) That's what my science teacher told me. He's weird.

No. Chlorine is highly reactive and as a result is not found in its free state in nature.

It's just one of the most active metals.  It has to do with it's valence.  It's even more reactive with water... it catches fire.  Its most stable form is as sodium chloride... table salt.  We put it on our food, but separately, sodium and chlorine are deadly poisons.  Chlorine is a green gas that's heavier than air and reacts with almost everything.  It turns water into hydrochloric acid, but turns sodium into sodium chloride.

(a) because Mg has valency +2 and chlorine -1

Probably to keep any chlorine produced from migrating over to the produced sodium. It reacts with the iron on its way.

sodium & chlorine to make NaCl, table salt

Ca(s) + 2HCl(aq)-->CaCl2 + H2(g)\n\nor...\n\nCalcium Chloride and Hydrogen Gas... you know... the stuff that fuels rockets! :)

Sodium Fluoride, about half of which is fluorine, from Sigma-Aldrich, is about $1200/kg.\n\nIndustrially, it would be cheaper.

yeah...it's called too much chlorine!

I suppose you meant Tungsten, it is about  is about $29 per kilo.\nor $290 per metric tonne unit, a measure equal to a hundredth of a tonne (approximately 22 pounds).
