Answer #1

Solution:- (1) Ksp values are given for the springly soluble compounds or the ones that we consider insoluble. NaCl is completely dissociated and water soluble. This is the reason why Ksp value for NaCl is not given in the appendix of the textbook.

(2) Tetraborate ion formula is B4O72- and it is a bicyclo compound. Each Boron atom has three single bonds with the oxygen atoms and two oxygen atoms would have negative charge as the ion has -2 charge. The structure would be as given below...

A college student is curious about undergraduate ownership of iPhones. She thinks that women might be more likely to own iPhones than men. To study this question, she gets permission from the human subjects committee to take a survey of students, then, with help from the Registrar, gets a list of SIDs of all enrolled undergraduate students. She shuffles the SIDs into a random order, then selects the first 34 SIDs from the shuffled list. The registrar sends email to...

1.)You are curious about how people feel about craft beer, so you gather data from 55 people in the city on whether or not they like it. You code your data so that 0 is neutral, positive scores indicate liking craft beer, and negative scores indicate disliking craft beer. You find that the average opinion was X̅ = 1.10 and the spread was s = 0.40, and you test for a difference from 0 at the α = 0.05 level....

Three Finance majors have differing opinions about TSLA stock, which currently trades at $700/share. Student 1 is very bullish (believes it will go way up) and decides to purchase shares of TSLA on margin. Student 2 feels the opposite and uses margin to sell short the same number of shares of TSLA. Student 3 isn’t sure but feels TSLA will be volatile over the next year and buys an ATM straddle. One year from today, TSLA trades at exactly $700/share....
