12 moles of each A and B are allowed to react as given : `3A + 2B rArr C + (1)/(2)D`. If 60g of D is produced then calculate the atomic mass of D.

One mole of A and 2 moles of B are allowed to react in a 0.5 lit flask. What is the value of K if at equilibirum, 0.4 moles of C is formed in the reaction A+2B Leftrightarrow C+2D

9 moles of "D" and 14 moles of E are allowed to react in a closed vessel according to given reactions. Calculate number of moles of B formed in the end of reaction, if 4 moles of G are present in reaction vessel.
