G prepare the standard solution of FeSCN2 by taking 9.00 mL of 0.2034 M Fe(NO3)3 from the dispenser into a 20 x 150 mm test tube. You pipet 1.00 mL of 0.001924 M KSCN into the same test tube and stir. The absorbance of this solution registers as 0.786 au on the spectrometer. Determine [FeSCN2 ]eq with units M and to 6 decimal places. Input your answer in decimal form. Your Question 11 options: Answer

Which element in the third period would you expect to have the larger atomic radius, sodium (na) or sulfur (s)? a. sodium, because it has a higher effective nuclear charge attracting electrons in fewer energy levels. b. sodium, because it has fewer protons attracting electrons in the same energy levels. c. sulfur, because it has more protons attracting electrons in more energy levels. d. sulfur, because it has a higher effective nuclear charge attracting electrons in the same energy levels.
