Is HBr example of element?
No, HBr is not an element. It is a compound made up of the elements hydrogen (H) and bromine (Br).
How many molecules are in 3.21 moles of HBr?
There are approximately 1.93 x 10^24 molecules in 3.21 moles of HBr. This can be calculated by multiplying the Avogadro's number (6.022 x 10^23) by the number of moles.
What is the chemical formula for Dextromethorphan HBr?
The chemical formula for Dextromethorphan Hydrobromide (HBr) is C18H25NO·HBr.
How many grams in 4.23 m mol of HBr?
The answer is 0,3422 grams.
Is Hbr non polar or Polar?
Polar!
Is HBr example of element?
No, HBr is not an element. It is a compound made up of the elements hydrogen (H) and bromine (Br).
What are the elements for hydrogen?
Hydrogen bromide (HBr) contain of course hydrogen and bromine.
Why is hydrogen bromide a compound?
Hydrogen bromide is a compound because it is composed of different elements (hydrogen and bromine) chemically bonded together. It has a distinct chemical formula (HBr) and properties that differ from its individual elements.
What is the net ionic equation for HBr and H2O?
HBr dissociates in water to form H3O+ and Br-. The net ionic equation is H+ + Br- -> HBr.
What kind of bond is HBr?
HBr is a polar covalent bond because hydrogen and bromine have different electronegativities, leading to an unequal sharing of electrons between the two atoms.
Is HBr am acid?
Yes, HBr is a strong acid. When it dissolves in water, it releases hydrogen ions (H+) which make it acidic.
How many moles are in 186 grams of HBr?
To find the number of moles in 186 grams of HBr, you need to divide the given mass by the molar mass of HBr. The molar mass of HBr is approximately 80.91 g/mol. So, 186 grams of HBr is equal to 2.30 moles.
Elements present in hydrobromic acid?
Hydrogen and Bromine. Similar to hydrogen chloride it dissolves in water to form hydrobromic acid.
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.
Write an equation for the reaction between methane and bromine to make bromoethane and hydrogen bromide?
CH4 + Br2 --> CH3Br + HBr
How many molecules are in 3.21 moles of HBr?
There are approximately 1.93 x 10^24 molecules in 3.21 moles of HBr. This can be calculated by multiplying the Avogadro's number (6.022 x 10^23) by the number of moles.
How many moles are in 135 g of hydrobromic acid?
In the English language hydrobromic acid is the solution of HBr in water; the name of the acid HBr is hydrogen bromide. 135 g HBr are equivalent to 1,67 moles.
