The ElementSymbol: Hg
Atomic Number: 80 Physical Properties Atomic mass average: 200.59 Boiling point: 357°C / 675°F / 630K Electrical conductivity: 0.0104 X 106 / cm Ohm Thermal conductivity: 0.0834 W / cmK Density: 13.546 g / cm3 at 300K Melting point: -38.72°C / -37.7°F / 234.28K Chemical Properties Mercury is moderately active. It does not react with oxygen in the air very readily. It reacts with some acids when they are hot, but not with most cold acids. |
Reactions of Mercury compoundsDouble displacement reaction of Mercury (II)nitrate:
Mercury(II) nitrate + potassium iodide → mercury(II) iodide + potassium nitrate Hg(NO3)2 (aq) + 2KI (aq)→ HgI2 (s) + 2KNO3 (aq) Decomposition reaction of Mercury (II) thiocyante: Mercury (II) thiocyanate → mercury sulfate + carbon disulphide + carbon nitride 2Hg(SCN)2 → 2HgS + CS2 + C3N4 |
Reactions of MercurySynthesis reaction with air at 350°C:
Mercury (II) + oxygen → Mercury (II) oxide 2Hg(s) + O2(g) → 2HgO(s) Synthesis reactions with halogens: Mercury (II) + fluorine → Mercury (II) fluoride Hg(l) + F2(g) → HgF2(s) Mercury (II) + chlorine → Mercury (II) chloride Hg(l) + Cl2(g) → HgCl2(s) Mercury (II) + bromine → Mercury (II) bromide Hg(l) + Br2(l) → HgBr2(s) Mercury (II) + iodine → Mercury (II) iodide Hg(l) + I2(s) → HgI2(s) Single displacement reaction with sulfuric acid: Mercury (II) + sulfuric acid → Mercury (II) sulfate + sulphur dioxide + water Hg(l) + 2H2SO4(l) → HgSO4(l) + SO2(l) + 2 H2O(l) Website by Jessie Elias |
