Here’s a good question. When they ask us to draw the structure of any molecule, should we ALWAYS draw its skeletal structure?
We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

If they don’t?they specify the structure
We can draw any of themIf they don’t?
I think if i remember correctly it was about weak acids brownsted theory for it i wrote:Does anyone remember the bronsted lowry acid question ? What did it actually say? Will this equation work : NH4+ + OH- > NH3 + H2O ,.
noI think if i remember correctly it was about weak acids brownsted theory for it i wrote:
Acids whose H+ ions dissociate incompletly in aqueous solution. Is it right?
And for equation: NH4 + H20= NH4OH + 0.5H2
no
you have wrote the definition of a weak arehenius acid
arhenius acid = a substance that dissolves in water to form H+ ions
bronsted lowery acid = proton doner (these acids can exist in any state not only aqueous)
anyways the definiton should have been
A weak bronsted lowery acid is one which partially donates proton.

It's better that you draw a skeletal structure (AS chem)If they don’t?
well atomisation is basically the half of bond energy for diatomic molecules such as O2 or Cl.Would you mind telling me how to find the Atomisation energy of gases? I always mix when to multiply and when to divide.

ok getting something nowwell atomisation is basically the half of bond energy for diatomic molecules such as O2 or Cl.
You see Hat is actually the enthalpy when 1 mole of atoms is produced.
But Bond energy is the enthalpy when one mole of bonds is broken.
So suppose if v break 1 mole of bonds of Cl2 or O2 then v will get 2 moles of atoms of each.
So to reduce it to one mole and make it Hat v dicide B.E. by 2.
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
