Answer:
mNaCl = mNa + mCl
mNa = 20g
mCl = mCl2/2 = 30/2 = 15g
mNaCl= 20+15 = 35g
Answer: Electronic transition moments are defined as the probability for a given excitation energy transition to take place. It should be evident that the transition moment depends upon the spin-orbit coupling of the electrons in both the ground and excited states.
Answer:
A- observation
B- hypothesis
C,D,E- experiment
F- conclusion
Explanation:
Lucia has just carried out the scientific process. An observation refers to paying close attention to a particular phenomenon in nature. This leads to the proposition of an intelligent guess about the observed phenomenon. This intelligent guess is called a hypothesis.
The hypothesis now guides the design of an experiment designed to confirm or disprove the hypothesis. The results of the experiment now leads to the formulation of a conclusion as Lucia has just done.
