the concept of “victim precipitation”. This theory views the victim as a participant in a crime. This is analysed in two ways. The aggressor and the provoked. Victim precipitation is defined as the extent to which the victim may have contributed directly or indirectly to their own victimization. The concept is that victimisation involves the victim and the offender‚ and it is the action and reaction of the parties that has lead one of them to become a victim. Victim precipitation is a behavioural

Victim Precipitation Theory defined is “The view that victims may initiate‚ either actively or passively‚ the confrontation that leads to their victimization (Siegel‚ 2014‚ p.67) Victims of domestic violence can unknowingly participate in the very crime that they are a victim of. Victim Precipitation Theory shows us how victims passively or actively participate in a crime committed against them. A victim can passively participate by unknowingly showing certain behaviors that might encourage the

AIM: To outline what a precipitation reaction is‚ describe ways which one can predict whether a precipitation reaction would form or not‚ describe the uses of precipitation reactions in everyday activities and industries BACKGROUND INFORMATION: Precipitation is the formation of a solid in a solution during a chemical reaction‚ such as evaporation. A substance that causes precipitation when it is added to a solution is called a precipitant. This can occur when an insoluble substance is formed in

Selective Precipitation of the Barium Magnesium Group ABSTRACT The purpose of this lab was to identify the cations from the barium magnesium group present in an assigned unknown solution through selective precipitation. This was a qualitative lab where the theory of the common ion effect was used in several steps. Once the experiment was completed‚ it was determined that unknown solution #4 contained Ba2+‚ Sr2+‚ and Mg2+ ions. INTRODUCTION Selective precipitation is a part of chemistry

Stoichiometry of a Precipitation Reaction Purpose: The purpose of this lab is to calculate the theoretical‚ actual‚ and percent yield of the product from a precipitation reaction. Also‚ to learn concepts of solubility and the formation of a precipitate. Procedure: Weigh out your 1.0g of CaCl2-2H20 and put it into the 100mL beaker‚ Add your 25mL of distilled water and stir to form the calcium chloride solution. Next‚ use stoichiometry to determine how much Na2CO3 and put it into a small

mole CaCO3 = 0.68g CaCO3 Show the calculation of the percent yield. = Actual yield/Theoretical yield x 100 = 0.5/0.68 x 100 = 73.5% Conclusion: The objective of the experiment is to predict the amount of product produced in a precipitation reaction using stoichiometry. Secondly‚ the experiment accurately measures the reactants and products of a reaction. Also‚ the experiment is to determine actual yield vs. theoretical yield and to calculate the percent yield. For example in this

Good Morning‚ today I xxxx am here to talk to you about ‘’The Earth” Let me begin by a famous quote- “ The Earth provides enough to satisfy every man’s needs‚ but not every man’s greed.” ― Mahatma Gandhi The urgent message is “Save the Earth”. It’s a message that has been heard before and consistently being spread throughout the world. In this time that I have to talk to you‚ I want to show to you‚ how deep a mess we are in‚ with environmental crisis and how we can get out of it. It warns us

Analyzing: “The Victims” by Sharon Olds “The Victims” by Sharon Olds is a poem‚ which gives us an elaborated and refined view of a tortured family in our modern society. It describes the immature resentment of the young speaker and her family towards the father‚ and the more mature expression of sympathy of the grown up speaker. The poem is divided into two parts‚ easy to spot due to a sudden change in the verb tenses‚ speaker‚ tone and purpose. The first part of the poem‚ transmits to the reader
