To test for halide ions (Br, Cl, Fl, I) use a silver nitrate solution and then an ammonia solution. Silver nitrate solution will form a precipitate with Cl, Br, and I. Cl precipitate will be white, Br cream, and I yellow. Confirm with the ammonia solution that the AgCl dissolves into a colorless solution. AgBr will do the same but in concentrated ammonia solution. AgI is insoluble in ammonia.

∙ 11y agoBromine is present as Br2 in the liquid and gas phases. This si a simple symmetric molecule Br-Br and has a dumbbell shape.
In the solid phase under normal pressures it is still present as Br2 molecules. It is reported that at extremely high pressures it becomes metallic which indicates that the molecular structure has changed to a Br lattice with delocalised electrons.

∙ 12y agoCBr4 will be tetrahedral because the C makes four bonds (each to Br) there are no additional unshared pairs around the C which means the only repulsion we have to worry about is the Br atoms repelling each other. Each Br is most separated if they can form bond angles of 109.5 and have a tetrahedral structure.
(tetrahedral is essential a pyramidal shape with one extra grouping on top)

Which is least polar HF HBr HCl or Hbr?
HBr
Is HBr a dipole dipole?
HBr has a dipole
Write the expression for Ka for the dissociation of HBr?
Ka = [H+].[Br-] / [HBr] However the value of this expression is very high, because HBr is a STRONG acid, meaning that much more than 99.9% of the HBr molecules in water are protolized (ionized), making [H+] and [Br-] equal to the original (added) HBr amount, and the [HBr]-value nearly zero.
If HBr is a weak base?
No. HBr is a strong acid.
What kind of bond is HBr?
HBr has an ionic bond.

Is hbr an electrolyte?
yes HBr is an electrolyte

What is the chemical formula for Dextromethorphan HBr?
C18H25NO•HBr
What kind of bond is HBr?
HBr has an ionic bond.
How many molecules are in 3.21 moles of HBr?
3.21 moles HBr (6.022 X 10^23/1mole HBr) = 1.93 X 10^24 molecules of HBr
Is hbr organic or inorganic?
HBr is inorganic as it does not contain carbon.
Is HBr an ionic covalent or acid?
HBr can refer to hydrogen bromide, the covalent molecule and hydrobromic acid which is HBr dissolved i water.
How many moles are in 186 grams of HBr?
For this you need the atomic (molecular) mass of HBr. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. HBr= 81.0 grams186 grams HBr / (81.0 grams) =2.30 moles HBr
Which has the highest ionic character HBr CaC2 N2 or OF2?
This compound is HBr.
