QUESTION 31 How many moles of CaCl2 are formed in the neutralization of 138 mL of 0.352 M Ca(OH)2 with aqueous HCl? (sig. figs. matter for this one) 8 points San QUESTION 32 3 points Save The visible spectrum falls between approximately 400 and 600 nm of the electromagnetic spectrum. True False 5 points Save QUESTION 33 subshell is partially filled. In a ground-state sulfur atom, the 4p OOO 5 points Save Ant QUESTION 34

Answer 1

the solutions are provided... hope this is helpful...please rate if this helps...thank you.

3 The neutralisation reaction of Ca (OH) with aqueous nu is given ass соон, 4 2ка » Сои, 121, о so, the no. of moles of calle formed is equivalent to the no. of modes of (604) in the reaction. so noles - Molarity & volume (in ) 0.352 x 138 1. 138 out = 138 L) 100 1000 E 48.576 lovo 0.0485 moles 4.85 x 10 moles 80 reoles of cally formed is : 14.85 x102 moles) 32 The visible spectrum frequency is about 400 - 40 nm. So the statement is - • True] 3) The sleeporowe configuration of sulfer is given as or s = [Ne] 39² 3p so, the 3p subshell is not completely filled, as the p orbital can accomodate 6 eleefrous but here only 4 electrons are present. & correct option is 8 [31]
