4. How many grams of zinc chloride can be formed from the reaction of 7.96 grams of zinc with excess HCL?\n\nZn + 2HCl → ZnCl2 + H2\n\n1 mole Zn produces 1 mole ZnCl2\nTherefore 65.7g Zn produces (65.7 + 2 x 35.5)g ZnCl2\nie ~65.7g Zn produces ~136.7g ZnCl2\nSo 7.96g Zn produces ~7. 96 x 136.7/65.7g ZnCl2\nie ~ 16.6g ZnCl2\n\n5. How many kilograms of copper sulfide could be formed from the reaction of 1.80 mol of copper with excess sulfur.\n\nCu + S → CuS\n\nSop 1 mole Cu produces 1 mole CuS\nTherefore 1.8 mole Cu produces 1.8 mole CuS\n1 mol CuS weighs ~(63.5 + 32.1)g = 95.6g\nSo 1.8 mol CuS weighs ~ 1.8 x 95.6g ≈ 172.1g = 0.1721kg\n\n6. If Copper(one) sulfide is partially roasted in air (reaction with 02), copper(one) sulfite is formed. Subsequently upon heating, the copper sulfite thermally decomposes to copper (one) oxide and sulfur dioxide. Write balanced chemical equations for these 2 reactions\n\nCu2S + 3O2 → Cu2SO3\nCu2SO3 → Cu2O + SO2

Rs. 36.50 per kg if you produce 100 kgs\n\nRs. 28.00 per kg if you produce more than 200 kgs\nand upto 350 kgs.\n\nIf 1000 kgs+ are produced the cost comes \ndown to Rs.18.00 only.

Alfa Aesar lists sodium ingots (99.8%) for $66 per pound.  Of course high purity versions would be more, bulk quantities less.

Assuming this is fine gold with a purity of 99.9% or better...\n\nThe current spot price of gold is: $718.40/Troy Ounce. (May 14, 2006)\n\n1 troy ounce = 31.1034768 grams\n\nSo, .8 grams = 0.02572059 troy ounces.\n0.02572059 * $718.40 = $18.48\n\nSo: $18.48, but not many people would buy such a small amount of gold unless you drop the price by about 10%, so your could probably sell it for: $16.63

I guess you mean how many grams of Zinc Sulphide could be produced\n\n65.4 g of Zn reacts with 32.1g S\n\nTo find out how much S 1 g of Zn can react with, divide both numbers by 65,4\n\n1 g of Zn reacts with 32.1/65.4 g S, which is 0,4908 g S\n\nFor 20 g Zn, if 1 g Zn reacts with 0,4908g S, 20 g will react with 0,4908*20g = 9.8g S.\n\nThe amount of Zinc Sulphide wil  therefore be the amount of Zn (20g) plus the amount of Sulphur with which it reacts (9.8g) giving you 29.8g total.\n\nOkay?

1/10 or a little more, that is, 35, 40 dollars but if the whole thing is gold you can get the market price by weight\n\ngo to this link and learn more about gold and gold price\n\nhttp://www.mine.mn/Prices_Metals_Minerals_Gems.htm

just a guess...but I would think the prices for steel/iron are by the pound...so you'd have to get it there and the more it weighs, the money you make

Well lets see 645kg uncut.. after cutting lets make it an even 1000kg for easy calculating. 1000kg = 1,000,000g\nHere in the states a g goes for about 50$.\nso 50 million dollars high estimate,say 30 million lowball\nconvert that to euros at .82 and u get 41 million to 25 million euros. approximately\n\n\n645kg is an INSANE amount of coke btw.

The density of wrought iron is 7.8 g/cm3 which translates to 7,800 kg/m3.\nHot dip galvanizing is a process by which steel is dipped in a zinc bath and coated to prevent rusting. Steel dipped in this process will gain about 6% weight.
