40. In an electrolytic cell, the mass of the cathode increases. Part C: Short Answer Questions (90 marks) Answer each of the following questions in the space provided 41. For the "Dancing Spaghetti" lab, give two observations and one inference based on these observations. (3 marks) OBSERVATION #1: OBSERVATION #2: INFERENCE 42. Fill in the missing information in the following chart: (4 marks) - Standard Atomic Notation Atomic Number Mass Number Number of Number of Number of protons electrons neutrons 26 197 79 79

Explanation / Answer

Mass number = no. of neutron + atomic mass

1) Mass number =55

atomic number = 26

no, of electrons = 26

no. of protons =26

no. of neutrons = 29

2) Mass number =197

atomic number = 79

no, of electrons = 79

no. of protons =79

no. of neutrons = 118
