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?

What are the elements for hydrogen?
Hydrogen bromide (HBr) contain of course hydrogen and bromine.
Why is hydrogen bromide a compound?
Hydrogen bromide (HBr) is a compound because it consists of two elements (hydrogen and bromine) that has been chemically combined to form a new substance. It is a colourless gas with an acrid odor at room temperature.
What is the net ionic equation for HBr and H2O?
how many planets are there? how many planets are there? how many planets are there?
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?
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
Elements present in hydrobromic acid?
Hydrobromic acid contains the elements Hydrogen and Bromine and has the formula HBr.
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.
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
Write an equation for the reaction between methane and bromine to make bromoethane and hydrogen bromide?
CH4 + Br2 --> CH3Br + HBr
What is the chemical formula for Dextromethorphan HBr?
