Thiosulfate \n\nThiosulfate is the anion S2O32-. Thiosulfates are only stable in neutral or alkaline solutions, but not in acidic solutions, due to decomposition to sulfite and sulfur, the sulfite being reduced to sulfur dioxide:\n\nS2O32-(aq) + 2H+(aq) → SO2(g) + S(s) + H2O\n\nThis reaction is usually used to generate a temporary aqueous suspension to demonstrate diffraction of light in physics. If the light is shone from below, blue light is seen from above, and orange from sideways.\n\nUses of thiosulfates include the dissolving of silver salts from photographic film.

I have forgotten all the chemical formulas & whatnot... but I'm going to do this assuming that I'm right for the following:\n\n(note that if i get any of these wrong you'll have to make appropriate changes, this is just to show you HOW to do this)\nCu = Copper\nS = Sulfur\nCuS2 = Copper Sulfide\n\nSo first step is to balance the equation\n\nCu + 2S -> CuS2\n\nso then you can set up a problem like this:\n\n0.90 mol Cu * 1 mol CuS2  = # mol copper sulfide yielded\n(this is because there was 1 mole of Copper in 1 mole of CuS2.. so if CuS2 is not the correct formula change the "1 mol CuS2" accordinginly)\n\n\nThen add up the # of grams in 1 mol of copper sulfide\n\ndo that by taking the # of grams in 1 mol of copper + the number of grams in 2 mol of sulfur (again, this is just assuming that copper sulfide IS CuS2).  Once you've gotten that figure, multiply it by the number found from the earlier problem (# mol copper sulfide yielded).  This gives you the amount of grams.  To change this number to kilograms, divide it by 1000.

No, it's Ag2S. The 2 is a subscript, denoting 2 Silver atoms to 1 Sulphur atom. Silver has a valency of 1+, while Sulpur has a valency of 2-, hence 2 Silver atoms are needed to balance with 1 Sulphur atom to form a compound. Besides, the equation would make sense then. 2 Silver atoms and 1 Sulphur atom on both sides of the equation, the equation is now balanced. 10 marks please, thank you!

sulfur forms S8...Cl forms Cl2...O is found as O2...N as N2\n\nps im a chem prof so i know;)

Here you are:\n\nCu2S + 12HNO3 => Cu(NO3)2 + CuSO4 + 10NO2 + 6H2O

the formula is NaO2\nthis is because the superoxide has the formula (O2)- and the sodium ion has the formula Na+

yes SO2 is liberated.The reaction is \nNa2SO3 + 2HCl -> 2NaCl + H2O + SO2\nformation of SO2 is favoured as water & sodium chloride are also formed with it , NaCl & H2O 's  formation is  thermodynamically favoured .

The first step is to balance the equation first, which yields\n\n2SO2 + O2 ---> 2SO3\n\nNow, find the total number of moles of 160 g O2:\n\n# of mole = 160/(16*2)\n= 5 moles.\n\nAccording to the balanced equation, the mole ratio between SO2 and O2 is 2:1. In other words, it takes twice amount (in moles) of SO2 to react with 1 unit of O2.\n\nSince we react 5 moles of O2, we need 10 moles of SO2.\n\nMass of SO2 = # mole * molecular weight\n= 10 * (32 + 16*2)\n= 640 g of SO2 is needed.

sulfuric acid is h2so4. convert 1600 kg to g so times by 1000. then take that number in grams and times by the molar mass of of sulfur (gSx1mol S/gS) then convert to moles of H2SO4 by using your balanced chemical equation(coefficients), with moles of S on bottom, moles of H2SO4 on top. everything cancels and your left with moles of sulfuric acid that you could make. if you need to take it another step to grams then you would then just use the molar mass of sulfuric acid.

You have some errors there:\n\nSO4 with the -2 charge has 4 bonded pairs and no lone pairs (unbonded pairs) on the sulfur (but three on each of the four oxygens, which I assume you are not counting).\n\nH2 is correct with 1,0\n\nH2O2 is correct with 3, 4 (two lone pair on each oxygen)\n\nCH2O has 4 bonded pairs (four between the carbon and the oxygen for a double bond) and 0 non bonded pair.\n\nCO2 has 4, 0, with double bonds between each oxygen and the central carbon\n\nHF, is 1,3\n\nCl2 is 1, 6, if you count the lone pairs on the two chlorine like you are doing with F in HF but not the O in SO4 with the -2 charge.\n\nSO2 has a resonance structure where three bonded pair are smeared over two bonds between the S and O.  There are six unbonded pair (3 per oxygen) on the two oxygen.\n\nCH4O, (methyl alcohol?, CH3OH?) has four bonded pair between the carbon and three hydrogen and the one oxygen.  The oxygen has another bonded pair for its hydrogen and two unbonded pair.  This is 5, 2 as you have it.

These are the right ones:\n\n2K(s) + 2H2O(l) ---> 2KOH(aq) + H2(g)\nH2SO4(aq) + 2KOH(aq) ---> K2SO4(aq) + 2H2O(l)\nCa(OH)2(aq) + 2HCl(aq) ---> CaCl2(aq) + 2H2O(l)
