Answer and Explanation:
The explanation given in the problem is correct but not totally encompassing.
Van der waals interactions are a type of hydrophobic interaction, in which they do not interact with the polar water molecule. Covalent bonds involve the sharing of electrons between atoms of relatively similar electronegativities, and are most often too strong to disrupt by polar molecules of water. Therefore, covalent bonds and van der waals forces have an Intrinsic bond strength value that is independent of the environment.
However, either the partial negative oxygen atom or the partial positive hydrogen atoms in water molecules disrupt hydrogen or ionic bonds. Water is known to form hydrogen bonds with other polar or charged molecules, thus reducing the strength of interaction these molecules would normally have in the absence of water. Basically, these compounds with Hydrogen or Ionic bonds ionize, whether partially or fully in water, thereby leading to a decrease in bond strength in water.
QED!
Just study it by looking it up
Answer:
alpha particle needs to be added to the equation.
Explanation:
Given;
atomic mass of Americium = 241
atomic mass of neptunium = 237
The difference in atomic mass of the radioactive elements given is calculated as;
241 - 237 = 4
The particle with atomic mass of 4 is alpha particle usually represented with helium atom.
Am²⁴¹ -----> He⁴ + Np²³⁷
Thus, alpha particle needs to be added to the equation.
