H2SO4 lewis structure?

Remember that in the case of the Sulfure or the Oxygen, you have to complete the amount of 8 electrones each, if you only leave single bond that will mean that the oxygens would only be using 6 out of 8 electrones, leaving the molecule extreamly unstable.

CuS + H2SO4 ===> H2S + CuSO4

H2SO4 + 2NaOH ----> 2H2O + Na2SO4\n\nYOU MUST SEPARATE AND CANCEL THE COMMON IONS (AQUEOUS ONES)

An acid and its conjugate base differs by a hydrogen cation (or proton) H+, so:\n\na. H2SO4 and HSO4-\nd. HCl and Cl-\ne. HF and F-\n\nare conjugate acid-base pairs

1. Start with what you know - H is one, so in HCl Cl is one. In H2SO4 the sulphate group has a valency of two since there are two hydrogens. And so on.\n\n2. Pick out elements that you regularly need to know and learn them off by heart.\n\n3. Use the periodic table; elements in the same groups have the same valency (not transition elements).

lewis dot structure shows the molecule's valence e-s and the bonding of the molecule \n\nit is very easy to draw \nhere are some hints for drawing lexis structure\nfirst you need to find out the valence e-s of that molecule i.e. h2O have 8 VALENCE e-s 2 from the hydrogens abd 6 from oxygen \nthere is is Carbon present in a molecule than carbon should be placed in the middle  if there is no carbon present than least electronegative atom should be in the middle \nput one or two or three pair(s) of electrons in the middle depending on the octet rule which states that all atoms want 8 valence e-s other than H, Be, and S. H bond to get 2 valence electron, Be bonds to get 6 valence e-s and S can get more than 8 valence electrons \nif you are confused or need help with any of the models just email me i will try my best to reply

Ferrous Hydrogen Sulfate is also called Iron (II) Hydrogen Sulfate.\n\nFe(HSO4)2  although FeH2(SO4)2 would also be correct.\n\nThe Hydrogen Sulfate anion is a Sulfuric acid with a single proton (Hydrogen) removed.  It has the formula:\n\n(HSO4)-1\n\nIt takes two of these to balance the charges on the Ferrous (+2)cation.

CuSO4.5H2O => CuSO4.H2O + 4H2O at 98*C (or 110*C)\nCuSO4.H2O => CuSO4 + H2O at 120*C (or 150*C)\nCuSO4 => CuO + SO2 + O2  at 650*C

Ionic. The ions are Na+ and HSO4-, and the HSO4- ion is partly ionized into H+ and SO4=.
