Answer:
Isomers are defined as the molecules or polyatomic ions which have similar molecular formula but different in arrangements of atoms.
Isomers can be found in food items carrying glucose (C6H12O6), galactose or fructose, they all have the same chemical formula but differ structurally and chemically.
Glucose is found in vegetables and milk, galactose found in dairy products, and Fructose is found in fruit juices.
Answer:
10.64
Explanation:
Let's consider the basic reaction of cyclohexamine, C₆H₁₁NH₂.
C₆H₁₁NH₂(aq) + H₂O(l) ⇄ C₆H₁₁NH₃⁺(aq) + OH⁻ pKb = 3.36
C₆H₁₁NH₃⁺ is its conjugate acid, since it donates H⁺ to form C₆H₁₁NH₂. C₆H₁₁NH₃⁺ acid reaction is as follows:
C₆H₁₁NH₃⁺(aq) + H₂O(l) ⇄ C₆H₁₁NH₂(aq) + H₃O⁺(aq) pKa
We can find the pKa of C₆H₁₁NH₃⁺ using the following expression.
pKa + pKb = 14.00
pKa = 14.00 - pKb = 14.00 - 3.36 = 10.64
Molecular mass of H2O is: 16+2*1=18
so moles of 40g of H2O is: 40/18=2.22
