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!
If you are given the number of
moles of sodium bicarbonate, use the balanced chemical equation. The molar mass
of the acetic acid is 60 grams per mole. Using stochiometric balance.
Number of moles of acetic acid =
3 moles NaHCO3 (1 mol CH3COOH/1 mol NaHCO3) = 3 moles of acetic acid
Grams of acetic acid = 3 moles
of CH3COOH (60 g CH3COOH/1 mol CH3COOH) = <span>180 grams of acetic acid</span>
In order for an atom to be stable it should have eight valence electrons in order to follow the octet rule the only exception to this rule is hydrogen as the maximum valence electrons it is able to hold is two
<span>The combined gas equation relates three variables pressure, temperature and volume when the number of moles is constant.
The equation is PV / T = constant. Which is valid for a fixed number of moles of the gas.
You can derive the combined gas equation from the combination of Bolye's law, Charles' law and Gay-Lussac's law, which needs some algebra.
Answer: option 2. number of moles.

Answer:
The correct answer is - cellular respiration is when <u><em>chemical</em></u> energy from sugar/glucose is converted to cellular <u><em>energy in the form of ATP</em></u><em><u>.</u></em>
Explanation:
Cellular respiration is a set of metbolic reaction that takes place inside the cell and breaking the sugars or nutrients to convert the chemical energy present in the nutrients into the cellular energy whic is used by cells that is ATP and release water and carbon dioxide as waste.
In this process the ammount of energy store in the cellular currecncy or ATP which is the form of energy that is utilized by the to perform its sunction. The chemical energy that is present in the nutrients or sugar is come from light energy which is stored in the nutrients by photosyntheis process.
