Answer:
The given statement is false.
Explanation:
Hydrogen bromide when dissolves in water it gives hydronium ions and bromide ions.The hydronium ions is due to association of hydrogen ion with water molecule.This means that hydrogen bromide is an acid.
Where as bases are those compounds which free hydroxide ion sin their aqueous solutions.
So, from this we concluded that HBr is not a base but an acid.

Answer:
%age Yield = 85.36 %
Solution:
The Balance Chemical Reaction is as follow,
C₆H₁₂O + Acid Catalyst → C₆H₁₀ + Acid Catalyst + H₂O
According to Equation ,
100 g (1 mole) C₆H₁₂O produces = 82 g (1 moles) of C₆H₁₀
So,
4.0 g of C₆H₁₂O will produce = X g of C₆H₁₀
Solving for X,
X = (4.0 g × 82 g) ÷ 100 g
X = 3.28 g of C₆H₁₀ (Theoretical Yield)
As we know,
%age Yield = (Actual Yield ÷ Theoretical Yield) × 100
%age Yield = (2.8 g ÷ 3.28 g) × 100
%age Yield = 85.36 %
