The following reaction reaches equilibrium at 350 c and i bar. q5 chch: ch + haa cas. cahs if the system initially contains i mole each of h; and cjlch ch (given: for ha. ahr agr"s -0 jmol; r-8.314 jmol. k). demonstrate the mole frnction of all species as function of reaction coordinates, c, for the reaction. (a) 4 marks) caleulate the equilibrium constant k, for the reaction at 350 "c. (b) (12 marks) detemine the mole fraction of cahsch; at equilibrium.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

the population of unionid mussels in the hudson river decreased after zebra mussels were introduced. zebra mussels, a nonnative species, competed with the unionid mussels for food. the zebra mussels were able to outcompete the unionid mussels, allowing the zebra mussel population to increase dramatically over six years. the unionid mussel population decreased due to a lack of food.

hope this :
