Aoa, can someone help plz
In your working, you should have wrongly used 100 as the dominator rather than 10.
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!

You can only count one Carbon from a single C=C bond ... as one ketone is formed from one C=C bond.Why we dont count the two blue ones > they are tertiary?
D rite?
YuppD rite?
If you can find them,post the links...The same quetions are repeated in the thread..
When temp is increased, rate increases for both forward & backward. When they ask you for yield, then you can say yield of Nh3 will decrease.The Haber process for the manufacture of ammonia is represented by the following equation.
N2(g) + 3H2(g) 2NH3(g) ∆H = –92kJ mol–1
Which statement is correct about this reaction when the temperature is increased?
A Both forward and backward rates increase.
B The backward rate only increases.
C The forward rate only increases.
D There is no effect on the backward or forward rate.
Why is the correct answer A? The reaction in exothermic so by increasing the temperature, won't the backward reaction increase only?
Thankyou! And yes I always keep thinking of the bond energies...I think you have asked similar questions on this? This question is on intermolecular forces of attraction. HCl has the strongest intermolecular attraction (PD-PD) compared to the other options (VDW).
ammonium salt + base --> salt + water + ammonia
It is "bad" because, the nitrogen nutrient which is meant to be taken in by the plants is lost to the surroundings as ammonia gas.
last que: n^2= no of cis trans isomers .where n is the no of double bonds.
Which mixtures, on heating, produce the gas ND3?
[D = H 2
1 , an isotope of hydrogen]
1 CaO(s) and ND4Cl(s)
2 CH3CN and NaOD in D2O
3 NDH3Cl and NaOD in D2O
So D is like H so we can suppose NDH3Cl as NH4Cl so wouldnt reaction 3 also liberate ammonia?The Ms says only 1,2 are correct.
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.
