Give me answer of this question. The normality of 10% (weight/volume) acetic acid is: (a)1 N (b)10 N (c)1.7 N (d) 0.83 N
Choose the right answer from following. If we take 44g of CO_{2} and 14g of N_{2} what will be mole fraction of CO_{2} in the mixture: (a) 1/5 (b) 1/3 (c) 2/3 (d) 1/4
I) Sulphur dioxide (SO2) with a volumetric flow rate 5000cm3/s at 1 bar and 1000C is mixed with a second SO2 stream flowing at 2500cm3/s at 2 bar and 200C. The process occurs at steady state. You may assume ideal gas behaviour. For SO2 take the heat capacity at constant pressure to be CP/R = 3.267
What do you mean by the term dipole moment? Briefly describe it.
