This is actually not a known compound in this form.  The closest is sodium thiosulfate also called sodium hyposulfite (Na2S2O3) or sodium hydrosulfite Na2S2O4-2H2O, also called dithionite or hyposulfite.  Sulfur tends to form multisulfur compounds with limited oxygen.\n\n\nSodium sulfide is Na2S.\nSodium sulfite is Na2SO3

The conjugate acid of any base B: is HB.  So the answers are HF, HSO4-, NH4+, and H2S+.  (Are you sure that wasn't supposed to be HS- and H2S?)

This compound is an amine.  You can identify it by the NH2 (amine group) at the end.  You did a fair job with the structure considering the limits of the text here.  I am sure you realize that two of your carbons do not have the correct number of bonds.

1.) 2Ni + O2 -->  2NiO  (since it's Nickel II and Oxygen has a charge of -2, but you always have to put oxygen in groups of 2)\n\n1.) 2H2O --> 2H2 +O2  (same with hydrogen)\n2.) 2Al2O3 (because Aluminum has a charge of +3) --> 4Al + 3O2\n3.) 2NaCl --> 2Na + Cl2 (basically the rest follow the same rules)\n4.) 2NH3 --> 3H2 + 2N\n5.) 2HgO --> 2Hg + O2
