what is the chemical equation for solid zinc sulfide + oxygen gas--> solid zinc oxide + sulfur dioxide gas?

The correct balanced equation is:\n2ZnS + 3O2 --> 2ZnO + 2SO2\nThis is BALANCED\nMr chemistry teacher, you didnt balance your equation,...and i'm in the ninth grade

Na2S (ag) + 2 AgNO3 (ag) --> 2 NaNO3 (ag) + Ag2S (cr)\n\nB. Double displacement.\n\nA. Ba(NO 3)2 and H2O\n\nB. If there is a double arrow (pointing in both directions), then it is an equilibrium reaction.\n\nC. Ba(OH)2 and HNO3\n\nD. Barium\n\nE. 6 oxygen atoms. \n\nF. Ba(OH)2

When you ask about the formula that is a pretty broad question.  The only formula I know is the balanced compound formula which is Ga2(SO4)3, direct combination formula which is 2Ga + 3S04 --> Ga2(SO4)3, or the decomposition formula which is, Ga2(SO4)3 --> 2Ga + 3S04.  If this isn't what you wanted I'm sorry, if you want you can email me and be more specific.

In PbSO4 the Pb is +2 and the SO4 group is -2. \nThe O in SO4 is -2 so the sulphur must be +6 (the four oxygens add up to -8 and for the SO4 group to be -2 the sulphur must be +6)\nThe formula for CaOCl2  IS  correct. The Ca is +2 and the OCl2 group -2 as O is usually -2 it would suggest that each chlorine is 0. This anomaly is because the OCl2 is known as a disproportionate ion (having too much chlorine).\nIn (NH4)2SO4  each NH4 group is +1 and the SO4 is -2.\nSo as each H = +1  the N is -3. The SO4 has the same oxidation numbers as in PbSO4 above.\nIn working out oxidation numbers we assume that certain elements have fixed numbers O is -2,  Cl is -1,  H is +1  and alkali metals like sodium and potassium are +1. The complete compound must add up to zero.

the above is correct EXCEPT the AgSO3 is silver sulfite, not sulfide, just AgS would be silver sulfide

2Cu(NO3)2 ----> 2CuO + 4NO2 + O2\nOBSERVATION: brown, choking fumes of NO2 evolved; black solid i.e CuO settles at the bottom\n\n2FeSO4 ----> Fe2O3 + SO2 + SO3 \nOBSERVATION: white fumes of SO3 evolved and reddish brown solid i.e. Fe2O3 formed\n\nEDIT: The above equation for iron(II)sulphate may be a supposed characteristic for its thermal decomposition relating to that of copper(II)nitrate above, but Chaos, O2 will not be evolved here, because SO3 will not get reduced to O2, even on strong heating.

first you have to balance the equation:\n2SO2+O2=2SO3\n\n1) 96gO2*(1moleO2/32g O2)= 3mole O2\n2) 3mole O2*(2moles SO3/1mole O2)=6mole SO3\n3) 6moles SO3*(80.1g SO3/1mole SO3)=480g SO3

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.

In the laboratory, sulfur dioxide can be prepared by the action of an acid on a sulfite; for example\n\n\n2HCl(aq) + Na2SO3(aq) ---> 2NaCl(aq) + H2O(l) + SO2(g)\n\nor \n\nby the action of concentrated sulfuric acid on copper:\n\n\nCu(s) + 2H2SO4(aq) ---> CuSO4(aq) +2H2O(l) + SO2(g)
