Pierre Chandon‚ Vicki G. Morwitz‚ & Werner J. Reinartz Do Intentions Really Predict Behavior? Self-Generated Validity Effects in Survey Research Studies of the relationship between purchase intentions and purchase behavior have ignored the possibility that the very act of measurement may inflate the association between intentions and behavior‚ a phenomenon called “self-generated validity.” In this research‚ the authors develop a latent model of the reactive effects of measurement that is applicable

ACTIVITY SERIES The activity series of metals is an list of metals ranked in order of decreasing reactivity to displace hydrogen gas from water and acid solutions. It can also be used to predict which metals will displace other metals in aqueous solutions. In introductory chemistry‚ the reactivity series or activity series is an empirical series of metals‚ in order of "reactivity" from highest to lowest. It is used to summarize information about the reactions of metals with acids and water‚ single

What is MBCT? Kabat-Zinn has developed the practice of combining CBT with mindfulness-based stress reduction (MBSR) program and named it “Mindfulness-Based Cognitive Therapy” (Segal et al.‚ 2013). Cognitive component includes education about depression‚ while mindfulness part covers meditation and simple yoga exercises (van der Velden et al.‚ 2015). Unlike CBT‚ where the focus is on the changing the thought context‚ MBCT patients observe the thoughts and learn to disengage from them. Therefore

Trends in Ionization Energy Period trends All the atoms in the same period have the same valence energy level and the same shielding. The increasing nuclear charge increases the attraction of valence electrons so ionization energy generally increases from left to right. The exceptions at full and ½ filled orbitals break the pattern because removing an electron from a stable (low energy) configuration will require more energy. Li has a low 1st ionization because 2 core electrons block the +3 nuclear

In order to find the formula of the copper chloride hydrate‚ we had to separate the compound to find the mass of water and copper. To begin this process‚ we evaporated the water and created an anhydrous compound‚ meaning we were left with only CuxCly. By calculating the weight of both the anhydrous and the hydrated compounds‚ we could conclude that the difference in the weights was the weight of the H2O. From this we were able to calculate the percent composition of CuxCly and H2O (see Calculations:

observing solubility with the naked eye. It was concluded that 5 of the combinations proved soluble‚ 2 completely insoluble‚ and 2 were insoluble at room temperature but soluble if heated. Also tested was the reactivity of cyclohexane and cyclohexene in sulfuric acid which tested to prove reactivity between cyclohexene but not cyclohexane. Finally tested was the reaction between bromine and alkenes‚ which showed reaction between the more polar alkenes than non polar. Introduction
