What compounds contain mercury?
Compounds that contain mercury include mercuric chloride (HgCl2), mercurous chloride (Hg2Cl2), and dimethylmercury (Hg(CH3)2). Mercury can also exist in elemental form, as mercury vapor.
What is the molecular formula of HgCl 472.2g mol?
The molecular formula of HgCl would be HgCl2. The molar mass of HgCl2 is approximately 472.2 g/mol, which corresponds to one mercury atom (Hg) and two chlorine atoms (Cl) in each molecule of mercury(II) chloride.
Which one of these names and formulae do not match N2O4 dinitrogen tetroxide or HgCl mercury II chloride?
The name and formula that do not match is HgCl with mercury II chloride. The correct formula for mercury II chloride is HgCl2. N2O4 matches dinitrogen tetroxide with the correct formula.
What is chemical compound HgCl3?
Mercury(III) chloride (HgCl3) is not a stable compound. Mercury typically forms compounds with a +1 or +2 oxidation state. The most common mercury chloride compounds are mercury(I) chloride (Hg2Cl2) and mercury(II) chloride (HgCl2).
According to the balance equation 2Co plus 3 Hg Cl2 equals 2 Co Cl plus 3Hg How many grams of mercuric chloride must react to give 5.11g of mercury?
To calculate the grams of mercuric chloride needed, we must first find the molar mass of HgCl2 (molar mass = 200.59 g/mol). Then, calculate the moles of mercury in 5.11g (moles = 5.11g / molar mass of Hg = 0.032 mol). Since the ratio of HgCl2:Hg is 3:1 in the balanced equation, you would need 0.032 mol of HgCl2 (0.032 mol Hg x 1 mol HgCl2 / 1 mol Hg = 0.032 mol HgCl2) which is equal to 6.42g of HgCl2 (0.032 mol HgCl2 x molar mass of HgCl2 = 6.42g).
