Use the band of stability to determine if europium-154 is a stable or unstable nucleus. hint: you must first find the atomic number to determine the number of protons and then use the equation, neutrons = mass number -protons, to find the neutrons a. n/z = 1.44, stable b. n/z = 0.69, stable c. n/z = 0.69, unstable d. n/z = 1.44, unstable answer

the answer is 0.42 is that is an option. this question provides no info

the answer is symmetrical : )

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 :
