it was lung cancer and chronic bronchitis.... emphysema do not have fatigue in symptoms...

emphysema does cause fatigue
The shortness of breath and low oxygen levels experienced by emphysema sufferers tends to lead to fatigue

salt analysis? was p33 tough? im giving p34 so i need to be prepared

 

[anonymous1122]

can u tell me about the paper ??? how was it ??

It was really easy
Simple acidbase titration with no dilution.
Enthalpy change of neutralisation. We had to make a graph aswell.
And salt analysis. Keep checking different forums because salts are usually leaked by the sources and people upload guesses which are almost always correct

 

[Abeha Malik]

yaa i m also giving 34 so i want to be prepared
