Question
Chapter 2, Problem 76E
Interpretation Introduction
Interpretation:
The concern about the wastage of energy resources is to be stated.
Concept introduction:
The Law of Conservation of Energy law states that energy can neither be created nor destroyed; rather, it can only be changed from one form to another. Different forms of energy are very precious for living as well as for non-living organisms.

- All structural types of Boron hydrides exhibit B-B, B-H-B and B-H bonds. Correct?arrow_forwardN-nitrosodimethylamine (NDMA) is a suspected carcinogen that can form via reactions between dimethylamine (DMA) and monochloramine (NH2Cl). The relevant elementary reactions and the corresponding rate constants are as shown below. Reaction Rate constant (M¹s¹) DMA + NH2Cl = DMCA + NH3 k =1.4×10-1, kr = 5.83×10-3 1.28×10-3 DMA + NH2Cl → UDMH UDMH + NH2Cl → NDMA -> 1.11×10-1 If the initial concentrations of DMA and NH2Cl are given, you should be able to predict the concentrations of all species at any given reaction time.

(a) How much NaOCI (kg) should you add? (Note: the equivalent weight of NaOCl is based on the reaction: NaOCl + 2H + 2 e→CI + Na +H₂O.) (10 pts) (atomic weight: Na 23, O 16, C1 35.5) (b) The pH in the pool after the NaOCl addition is 8.67. To improve disinfection, you want at least 90% of the TOTOCI to be in the form of HOCI (pKa 7.53). Assuming that HOCI/OCI is the only weak acid/base group in solution, what volume (L) of 10 N HCl must be added to achieve the goal? (15 pts) Note that part a) is a bonus question for undergraduate students. If you decide not to work on this part of the question, you many assume TOTOCI = 7×10-5 M for part b).arrow_forward
