Does water have a polarity pattern consistent with the electro-negativity values of O and H?
Yes, it is correct.
In column chromatography separation of p-nitroaniline and o-nitroaniline which will be aluted first and why?
o-nitroaniline will elute first in column chromatography because it has a lower affinity for the stationary phase due to its higher polarity compared to p-nitroaniline. This results in o-nitroaniline moving more quickly through the column and being eluted first.
Which direction should the polarity arrows point if P - O and P - S?
The polarity arrow should point from sulfur (S) to phosphorus (P) in P - S bond as sulfur is more electronegative than phosphorus. In the case of P - O bond, the arrow should point from oxygen (O) to phosphorus (P) as oxygen is also more electronegative than phosphorus.
What is the theoretical yield of aluminum oxide if 1.60 Mol of aluminum metal is exposed to 1.50 Mol of oxygen?
To determine the theoretical yield of aluminum oxide (Al₂O₃), we start with the balanced chemical reaction: 4 Al + 3 O₂ → 2 Al₂O₃. From the stoichiometry, 4 moles of aluminum react with 3 moles of oxygen to produce 2 moles of aluminum oxide. Given 1.60 moles of aluminum, we can find the limiting reactant. Since 1.60 moles of Al would require 1.20 moles of O₂ (which is less than the available 1.50 moles), aluminum is the limiting reactant. Thus, 1.60 moles of Al can produce 0.80 moles of Al₂O₃ (from 2 moles Al producing 1 mole Al₂O₃), so the theoretical yield of aluminum oxide is 0.80 moles.
What problems are there with reverse polarity?
Reversing polarity ,changes the rotation of the device you are changing polarity on.
List the following bonds to hydrogen in order of increasing polarity C-H O-H Al-H N-H?
Al-h , c-h, n-h, o-h
What does AL NA and O are symbols for?
It is Al, Na and O. Al is aluminium, Na is sodium and O is oxygen
What makes water an effective solvent?
The polarity of the H-O bond.
Who has entered every Olympic games?
The only athlete known to have competed in every Olympic Games since their modern inception in 1896 is the legendary gymnast and multiple Olympic medalist, Paul Elvstrøm from Denmark. However, he is not the only athlete to have participated in multiple Olympics; many have competed in consecutive Games, but Elvstrøm's distinction comes from his longevity in the sport across numerous decades. The title of being the only participant in every single Olympic Games is often associated with various athletes, but it's essential to clarify the context, as this can refer to different events over time.
Why is carbon dioxide a non polar molecule while water is polar molecule?
Carbon dioxide is linear any polarity in the C=O bonds cancel each other out. Water is bent the polarity in the O-H bonds does not cancel

How does a drawing of polarity water and the bond polarities make a major contribution to the overall molecular polarity look?
The polarity is a vector quantity. The resultant of the polarity of bonds determines the polarity of the molecule. In CO2 there is polarity between the two C-O but the polarity is equal and opposite in direction so CO2 doesn't have polarity. If the polarity of bonds is not cancelled then the polarity remains in the molecule.
Does water have a polarity pattern consistent with the electro-negativity values of O and H?
Yes, it is correct.
