Which is faster to effuse HCl or HBr?
Hydrogen chloride (HCl) will effuse faster than hydrogen bromide (HBr) because HCl has a lower molar mass than HBr. This means HCl particles have higher average speeds, allowing them to pass through a small opening more quickly than HBr particles.
Why HBr is weaker Acid than HCl?
HBr is a weaker acid than HCl because the bond between hydrogen and bromine is longer and weaker than the bond between hydrogen and chlorine. This makes it easier for HCl to release its hydrogen ion in solution, making it a stronger acid compared to 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 a dipole dipole?
Yes, HBr is a polar molecule with a significant difference in electronegativity between hydrogen and bromine atoms. This results in a permanent dipole moment, making it exhibit dipole-dipole interactions with other polar molecules.
Which is most polar HBr HCl HI?
HI is the most polar among HBr, HCl, and HI because iodine (I) is larger and more electronegative than bromine (Br) and chlorine (Cl), leading to a greater electronegativity difference between hydrogen and iodine in HI.
Is Hbr non polar or Polar?
Polar!

HBr is a stronger acid than HCl?
Actually, HCl is a stronger acid than HBr. This is because the strength of an acid is determined by its ability to dissociate and donate a hydrogen ion. HCl completely dissociates in water, while HBr partially dissociates, making HCl a stronger acid.
What are six strong acids?
HCl, HBr, HI, HNO3, H2SO4, HClO4
Which is the fourth strong acid?
Hydrochloric acid.HClO4 >> HI >> HBr >> HCl >> H2SO4
Compare the strength of hydrogen bond in HF HCl HBr HI?
HF > HCl > HBr > HI Hydrogen-bond strength is determined by the electronegativity difference; since fluorine has the smallest radius, it exerts the greatest attractive force over the H+ cation, creating the strongest bond.
What minimum mass of HCl in grams would you need to dissolve a 2.2 g iron bar on a padlock?
3.8 g Fe * 1 mol Fe/55.85 g Fe (molar mass) = .0680 mol Fe .0680 mol Fe * 2 mol HBr/1 mol Fe (found in formula Fe+2HBr=>FeBr2+H2)=.136 mol HBr .136 mol HBr*80.912 g HBr/1 mol HBr=11.004 g HBr (or 11 using 2 sig figs) And the mass of H2 that is produced is 0.14 g
