a last name is the name after your first name like Sarah the first name and smith the last name. The family name, the surname.
nope its a chocolate name and who would name anybody that name because that name is a stupid and useless name
All I think about the name VanBenschoten is that the name is a boys name.
it is bangladeshi and not a last name because my name is tashkir it is bangladeshi and not a last name because my name is tashkir
which ever one dies it will have the other ones name
To make a 0.01 M solution of HgCl, you need to know the molar mass of HgCl, which is 271.5 g/mol. With this information, you can calculate that 11.75 g of HgCl is equivalent to 0.0433 moles. For a 0.01 M solution, you would need 4.33 g of HgCl. Subtracting the initial 11.75 g, you find that 7.17 g of water is needed to make the solution.
Hg+Cl->HgCl
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.
HgCl is the chemical formula for mercury(II) chloride, a toxic substance commonly used in chemical laboratories for various purposes such as as a reagent in organic synthesis and as a catalyst in chemical reactions. It is a white solid at room temperature and highly soluble in water.
HgCl2 - mercury(II) chloride. Hg2Cl2 is mercury(I) chloride
2KI + HgCl₂ -----> 2KCl + HgI₂
c4 +H10 --->CO+ H2O
A single mercurous ion has two positive charges and contains two mercury atoms and therefore has the formula Hg2+2. This cation requires two chloride anions, each which has a single negative charge, for the electroneutrality required in a compound between them, resulting in the formula given.
The reaction is: Na2CO3 + 2HCl = 2NaCl + CO2 + H2O The net ionic is CO32- + 2 H+ = H2O + CO2
To prepare Hager's reagent for alkaloid testing, dissolve 1 gram of mercuric chloride (HgCl₂) in 100 mL of distilled water. This solution can be used to precipitate alkaloids in plant extracts, forming a yellow precipitate that indicates the presence of alkaloids. Ensure to handle mercuric chloride with care, as it is toxic and hazardous. Store the prepared reagent in a dark glass bottle to protect it from light.
Since mercury can be either a 1+ ion called mercury(I), or a 2+ ion called mercury(II), there are two possibilities.Formulaspotassium chloride is KClpotassium iodide is KImercury(I) chloride is HgClmercury(I) iodide is HgImercury(II) chloride is HgCl2mercury(II) iodide is HgCl2Equation with Mercury(I)KCl + HgI --> HgCl + KIEquation with Mercury(II)2KCl + HgI2 --> HgCl2 + 2KI
S2Cl2 = disulfur dichloride, Cl-S-S-ClHg2Cl2= mercury (I) chlorideThe mercury (I) cation is Hg2^2+. It is sort of a diatomic ion. In the +1 oxidation statethere is no single Hg. In other words, HgCl does not exist. HgCl2 does exist, except in this case, mercury is in the +2 oxidation state.The only thing you have to remember is that there are no single mercury (I) ions, mercury (I) exists as Hg2^2+.I don't think Hg2Cl2 will be very ionic, what with an electronegativity difference of 1.16. That translates to a percent ionic character of 28.6 for the Hg-Cl bond.Hg2Cl2 would NOT be named mercury chloride. Mercury requires a Roman numeral in the stock system.Or you could name Hg2Cl2 as mercurous chloride.
