1 mole of HNO3 produces 1 mole of H+
So [H+] = 1.189 x 10 -4 M

(2) 2NO2 + H2O ---> 2HNO3
Given mass of NO2 is , m = 5.47 mg
= 5.47 x 10 -3 g Since 1 mg = 10 -3 g
Volume of the solution , V = 1.0 L
Molar mass of NO2 is = 14 + (2x16) = 46 g/mol
So Molarity of NO2 , M = ( mass/Molar mass) / Volume of the solution
= ( 5.47 x 10 -3 / 46 ) / 1.0
= 1.189 x 10 -4 M
According to the balanced equation,
2 mole of NO2 produces 2 moles of HNO3
So the concentration of HNO3 is = 1.189 x 10 -4 M
HNO3 ---> H+ + NO3-
1 mole of HNO3 produces 1 mole of H+
So [H+] = 1.189 x 10 -4 M

Question Answer 1 True The corpus callosum , otherwise called the callosal commissure, is a wide, level heap of neural filaments around 10 cm long underneath the cortex in the eutherian cerebrum at the longitudinal gap. It associates the left and right cerebral sides of the equator and encourages interhemispheric correspondence. It is the biggest white matter structure in the mind, comprising of 200–250 million contralateral axonal projections. The (back) bit of the corpus callosum is known as the splenium; the foremost (front) is known as the genu (or \"knee\"); between the two is the truncus, or \"body\", of the corpus callosum. The part between the body and the splenium is frequently extraordinarily contracted and along these lines alluded to as the \"isthmus\". The platform is the part of the corpus callosum that ventures posteriorly and poorly from the anteriormost genu, as can be seen on the sagittal picture of the cerebrum showed on the privilege. The platform is so named for its likeness to a winged creature\'s mouth. Corpus callosum On either side of the corpus callosum, the filaments transmit in the white matter and go to the different parts of the cerebral cortex; those bending forward from the genu into the frontal flap constitute the forceps foremost, and those bending in reverse into the occipital projection, the forceps back. Between these two sections is the fundamental body of the filaments which constitute the tapetum and expand along the side on either side into the transient projection, and cover in the focal part of the horizontal ventricle. 2 False Ramus communicans (plural rami communicantes) is the Latin expression utilized for a nerve which associates two different nerves, and can be deciphered as \"conveying branch\".When utilized without further definition, it quite often alludes to an imparting branch between a spinal nerve and the thoughtful trunk. All the more particularly, it generally alludes to one of the accompanying : Dark ramus communicans White ramus communicans The dark and white rami communicantes are in charge of passing on autonomic signs, particularly for the thoughtful sensory system. Their distinction in tinge is brought about by contrasts in myelination of the nerve filaments contained inside, i.e. there are more myelinated than unmyelinated filaments in the white rami communicantes while the opposite is valid for the dim rami communicantes. 3 False tentorium cerebelli isolates the occipital flaps of the cerebral sides of the equator from the cerebellum. Its inward, sunken, free fringe adds to the tentorial indent. (See underneath.) The outer, arched fringe encases the transverse sinus where it appends to the dura over within the occiput. Past the \"petrous edge,\" the tentorium is tied down to the foremost and back clinoid forms 4 False myelin sheath(deep) and Neurilemma (superficial) 5 False Cranial nerves are the nerves that develop straightforwardly from the cerebrum (counting the brainstem), a.

APM webinar hosted by the Scotland Network on 14 May 2024. Speakers: Chris Drysdale and Peter Huggett An interactive session discussing how Project Managers can identify mental health symptoms, provide tools to help themselves and others, plus also increase the capabilities of the Project Management function. This webinar was held on 14 May 2024. The covid-19 pandemic led to concerns about a worsening of mental health & wellbeing across the world and increased awareness in both society and the workplace. This webinar looks to advise the benefits of having a Mental Health First Aid function in the workplace whilst also providing tools and techniques that can be readily used and applied to yourself and colleagues. Additionally, there are wider benefits to Project Management which will be proposed and discussed.

Program code examples (known also as worked examples) play a crucial role in learning how to program. Instructors use examples extensively to demonstrate the semantics of the programming language being taught and to highlight the fundamental coding patterns. Programming textbooks allocate considerable space to present and explain code examples. To make the process of studying code examples more interactive, CS education researchers developed a range of tools to engage students in the study of code examples. These tools include codecasts (codemotion,codecast,elicasts), interactive example explorers (WebEx, PCEX), and tutoring systems (DeepTutor). An important component in all types of worked examples is code explanations associated with specific code lines or code chunks of an example. The explanations connect examples with general programming knowledge explaining the role and function of code fragments or their behavior. In textbooks, these explanations are usually presented as comments in the code or as explanations on the margins. The example explorer tools allow students to examine these explanations interactively. Tutoring systems, which engage students in explaining the code, use these model explanations to check student responses and provide scaffolding. In all these cases, to make a worked example re-usable beyond its presentation in a lecture, the explanations have to be authored by instructors or domain experts i.e., produced and integrated into a specific system. As the experience of the last 10 years demonstrated, these explanations are hard to obtain. Those already collected are usually “locked” in a specific example-focused system and can’t be reused. The purpose of this working group is to support broader re-used of worked examples augmented with explanations. Our current plan is to develop а standard approach to represent explained examples. This approach will enable an example created for any of the existing systems to be explored in a standard format and imported into any other example-focused system. We plan to follow a successful experience of the PEML working group focused on re-using programming exercises.

(1) Acid rain occurs when the gases SO2 ,NOx react with water,oxygen.pdf

1. (1) Acid rain occurs when the gases SO2 ,NOx react with water,oxygen, and other chemicals in the atmosphere to form various acidic compounds. Sunlight increases the rate of most of these reactions. The result is a mild solution of sulfuric acid and nitric acid. Acid rain causes acidification of lakes and streams and contributes to damage of trees at high elevations and many sensitive forest soils.
