1: how many total electrons in an atom can ahve the following two quantum umbers: n=2, ml = 0?what orbital is each of the electrons housed in?Explain your reasoning and how you came about this answer.Think about all four quantum numbers (n,l,ml,ms) to answer this question. Please explain in written form with details.
2: write the full electron configuration of rhodium (Rh) which is a transition metal.How did you know the order to fil the electrons?how did you know when to stop adding electrons and what the final orbital should be ? would you expect Rh to be paramagnetic or diamagnetic? Explain your answer to each question? please explain in details so its easy for me to understand this.
Write the structure for the organic reagents and products, name the products and indicate stereochemistry when appropriate
A metal object with a mass of 19g is heated to 96c, then transferred to a calorimeter containing 75g of water at 18c. The water and teh metal object reach a final temperature of 22c.
