Potassium bicarbonate (KHCO3) and hydrobromic acid (HBr) will react to form potassium bromide (KBr), water (H2O), and carbon dioxide (CO2). Here's the balanced equation:
KHCO3 + HBr --> KBr + H2O + CO2
(A closer look actually tells you that the other product besides potassium bromide is carbonic acid, H2CO3; but under normal conditions, that quickly decomposes into water and carbon dioxide, so the above equation actually reflects two different reactions: one double replacement and one decomposition.)

What is the chemical formula for Dextromethorphan HBr?
The chemical formula for Dextromethorphan Hydrobromide (HBr) is C18H25NO·HBr.
Is Hbr non polar or Polar?
Polar!
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
What was done in the experiment to ensurethat all KHCO3 was react?
In the experiment, excess HCl was added to ensure that all KHCO3 was reacted. Excess reactants ensure that all of the limiting reactant is completely consumed in the reaction, leaving none unreacted. When all KHCO3 reacts, the reaction reaches completion.
Is hbr an electrolyte?
No, hydrobromic acid (HBr) is not classified as an electrolyte because it primarily exists as a molecular compound rather than dissociating into ions in water, which is a characteristic of electrolytes.
When KHCO3 reacts with HBr the product is?
The products are Potassium bromide(KBr), Water(H2O) and Carbon(CO2). KHCO3 + HBr ----> KBr + H2O + CO2
What is the equation for reacting KHCO3 with H2O?
Khco3+h2o
Formula for potassium bicarbonate?
First off, it's POTASSIUM. (K) The formula would be: KHCO3
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.
What is the chemical formula for potassium hydrocarbonate?
More commonly known as potassium bicarbonate KHCO3
What is the chemical formula for Dextromethorphan HBr?
The chemical formula for Dextromethorphan Hydrobromide (HBr) is C18H25NO·HBr.
What was done in the experiment to ensure that all KHCO3 was react?
In the experiment, excess HCl was added to the solution containing KHCO3. This ensured that all of the KHCO3 would react completely, as any unreacted KHCO3 would still be neutralized by the excess HCl.
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
Why is the mass of KCL recovered less the starting mass of KHCO3?
The mass of KCl recovered is less than the starting mass of KHCO3 because during the chemical reaction between KHCO3 and HCl to form KCl, CO2 gas is evolved. Some of the starting mass of KHCO3 is lost as gas during the reaction, leading to a lower mass of the end product (KCl) compared to the original mass of KHCO3.
Is khco3 soluble?
Yes, potassium bicarbonate (KHCO3) is soluble in water. It dissolves readily to form a clear solution.
The maximum number of grams of potassium that can be obtained from 100 grams of KHCO3 is?
The molar mass of KHCO3 is 100.12 g/mol. This means that 100 grams of KHCO3 contains 39.1 grams of potassium (K) ions.
What is hydrobromic acid symbol?
The chemical formula of hydrobromic acis is HBr.
