Introduction Halogen bonding, XB, is the product of a non-covalent interaction between a halogen X and a negative site B (e.g., Lewis base). The halogen, X, is usually part of an R-X molecule where R can be another halogen, an organic or an inorganic electron-donating-group. Halogen bonding (XB) is in some ways analogous to hydrogen bonding (HB). In the latter, a hydrogen atom is shared between an atom, group or molecule that “donates” and another that “accepts” it.[1-3] In halogen bonding, it is a halogen
Can counseling address the issue of emotional eating? Just as any other maladaptive behavior is used to cope with difficult feelings; counseling for an emotional eating disorder (ED) can be considered a means to cognitively adjust behavioral responses to negative emotions. Emotional eating is a behavioral response to negative emotional states in which individuals increase food intake. This form of disordered eating can be caused by many factors especially stress. Emotional eating is a common
9.1 Orbitals and Theories of Chemical Bonding 1. Which one of the statements concerning valence bond (VB) and molecular orbital (MO) bond theories is correct? a) MO theory predicts that electrons are localized between pairs of atoms. b) In VB theory, bonding electrons are delocalized over the molecule. c) MO theory accurately describes bonding in O2 and NO, VB theory does not. d) VB theory can describe molecular bonding in excited states. e) MO theory is used to accurately predict
Abstract Research indicates that development of friendships begins in preschool ages 3 to 5. As communication skills increase, the desire to develop close friendships also increases during preadolescence and adolescence. Ability to develop communication skills that are conducive to forming close friendships determines the kind and an on occasion the number of friendships an individual has. Individual approaches to friendship are linked to attachment style (self esteem and interpersonal trust).
Metal-Only Lewis Pairs with Transition Metal Lewis Basas Introduction: History of Metal-Metal Dative Bonding Concept In 1961, Vaska and Diluzio synthesized a lemon-yellow compound known as the organometallic complex trans-[IrCl(CO)(PPh3)2]. This was achieved by reducing iridium(III) to iridium(I) using just triphenylphosphine and an alcohol. This was significant because they had prepared an iridium carbonyl complex without the use of carbon monoxide. This complex has reversible dioxygen coordination
Love's Path- Personal Narrative They say it is better to have loved and lost, than to have never loved at all. Those words are not comforting to me. But, I love you Deborah, he says as we sit on the couch in my basement, his voice shaky, and uncertain. He looks into my eyes as if pleading, no, begging for forgiveness. I don't recognize these eyes that once provided me with happiness, security, and comfort. These eyes used to reassure me that indeed he did --used to love me. It hurts to look
in my long term memory. General Chemistry just had a test last week so I am attempting to store new information, specifically from Chapter 10 tilted Chemical Bonding. We have covered bond theories and have worked extensively on the Lewis Dot structure. The Lewis Dot structure represents the boding of valence electrons, we represent this bonding using dot structures. There are different types of chemical bonds that must be represented with their very own dot structure. We are also learning when a bond
Hi, I am Arabella, a junior in high school and a varsity cheerleader at Siesta Key High School. I am four feet and eight inches tall and a flyer on the cheer team. I often dress like a nerd, and do not care what other people think. I am dating the star football player at SKHS his name is Tom. Tom was not only a star football player, but he is also very good at soccer, basketball, baseball and volleyball. He is a liar and a cheater too. Anyways, people just call me Bella. I love sports and love spending
Whether you eat a whole tub of chocolate ice cream while crying or you party like a rock star all weekend while drinking, a break up is a break up. If you’re the person who eats a whole tub of chocolate ice cream, you probably accompanied it with romantic movies. Although they are comforting for the time being, they always leave you to wonder, why didn’t my break up didn’t have a happy ending like the ones in the movies? In Peyton Reed’s 2006 romantic comedy, The Break-Up, it portrays the realistic
The disadvantages of Task-Oriented Leaders Behaviour: • Decreased Motivation The task oriented leaders will mostly focused on the task of the employees itself. The leader will have a high influence on how the job should be done, most of the leaders with this type of leadership behavior will guide the employees to proceed the task based on the leader presepective, the leader wants everything under his or her monitored. This condition could give a negative impact in case of employees’s job satisfaction
