Answer:

hello your question lacks some parts below are the missing option

A. hydrophobic interaction

B. nucleophilic attack

C. tautomerization

D. resonance

answer : Tautomerization ( C )

Explanation:

The large negative free energy of hydrolysis of Phosphoenolpyruvate is largely due to tautomerization of the enol pyruvate. tautomerism of enol takes place by transferring proton from in an intramolecular way.

one of the most common tautomerism is keto-enol which makes uses of either an acid or base as a catalyst

Determine how many gmol, kmol, and lbmols there are in 50 kilograms of n-hexane.

Artist 52 [7]

Answer: 581 gmol

0.581 kmol

$1.28\times 10^{-3}lbmol$

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}=\frac{50\times 1000g}{86g/mol}=581mol$

1. The conversion for mol to gmol

1 mol = 1 gmol

581 mol= $\frac{1}{1}\times 581=581gmol$

2. The conversion for mol to kmol

1 mol = 0.001 kmol

581 mol= $\frac{0.001}{1}\times 581=0.581kmol$

3. The conversion for mol to lbmol

1 mol = $2.2\times 10^{-3}lbmol$

581 mol= $\frac{2.2\times 10^{-3}}{1}\times 581=1.28\times 10^{-3}lbmol$
