Potential energy is given by:

Where U is potential energy, m is mass, g is acceleration due to gravity, and h is height. Using this equation:

Answer:
saturated fats
Explanation:
bcoz it is solid at room temperature and does not have double bonds between carbons
Answer:
The atoms become cations because they have lost electrons and the atoms and has a positive charge then atoms become a ions because they have gained electrons from cations and has a negative charge
Calculate the ratio by using Henderson-Hasselbalch equation:
pH = pKa + log [neutral form] / Protonated form
3.05 = 2.21 + log [neutral form] / [Protonated form]
3.05 - 2.21 = log [neutral form] / [Protonated form]
0.84 = log [neutral form] / [Protonated form]
[neutral form] / [protonated form] = anti log 0.84 = 6.91
