Sunlight, soil, water, leaves,
27/208 = normality
12 x 10^-2 approx = normality
nw Ka = 14.3 x 10^-3
pKa = 3 - log 14
now, after getting the pKa put it in formula :
pH = pKa + log concn of ion/concn of salt and you'll get it
hope this helps
Answer:
Pulmonary oedema can be caused by lung disease, but when heart failure is more serious, the pressure of blood in the lungs builds-up, pushing fluid into the air sacs. This is how heart failure can lead to respiratory failure. People with pulmonary oedema will feel breathless, weak and unwell.
Using ideal gas equation, PV = nRT, and since there is no volume change and amount change, the equation is now P = kT, where k =nR/V. Temperature must be in kelvin
From the given, k = (0.82)/ (21 + 273) = 2.78 x 10^-3
Substituting T = -3.5+273, P = 0.75 atm
