HCl effuses faster due to less molecular mass (36.5) as compare to HBr (81).
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.
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.
HF is the least polar among these molecules because it has the smallest difference in electronegativity between the hydrogen and the fluorine atoms.
When potassium bromide (KBr) reacts with hydrochloric acid (HCl), a double displacement reaction occurs producing potassium chloride (KCl) and hydrogen bromide (HBr). The reaction can be represented as follows: KBr + HCl → KCl + HBr.
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.

HCl, HBr, HI, HNO3, H2SO4, HClO4
Hydrochloric acid.HClO4 >> HI >> HBr >> HCl >> H2SO4
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.
No, oxygen does not effuse 1.07 times faster than nitrogen. The effusion rate of a gas is inversely proportional to the square root of its molar mass, so the effusion rate of oxygen would be √(Molar mass of nitrogen / Molar mass of oxygen) ≈ √(28.02 / 32) ≈ 0.91 times faster than nitrogen.
This gas is hydrogen, a gas with small molecules.
Nitrogen will effuse faster, since it has a smaller molar mass than iodine. Hope this helped!
HNO2 does not behave as a strong acid when dissolved in water. It is a weak acid, whereas HBr, HCl, and HClO4 are strong acids.
The balanced equation for potassium bromide (KBr) and hydrochloric acid (HCl) reacting is: KBr + HCl → KCl + HBr. This reaction is a double displacement reaction, where potassium chloride (KCl) and hydrobromic acid (HBr) are formed.
