Determining an enthalpy change of a displacement reaction Aim: To determine the enthalpy change for the displacement reaction between zinc powder and copper (II) sulphate solution. Zn (s) + Cu2+ (aq) → Cu2+ (s) + Zn2+ (aq) Theory: For the displacement reaction‚ an excess amount of zinc powder is added to the measured amount of aqueous copper (II) sulphate. The temperature change over a period of time has to be measured and thus‚ the enthalpy change for the reaction can be measured. The equation of the

Lab 2 Sara Rodriguez Period 2 Purpose: What is the more accurate way to measure volume‚ by using displacement or by using a ruler? Hypothesis: If the method of displacement is used ‚ then the results will be more accurate than measuring the volume using a ruler. Materials: -250 mL graduated cylinder -Triple beam balance -A weigh boat -Ruler -Samples Procedure: 1. Gather materials such as ‚ samples‚ weigh boat‚ triple beam balance ‚ graduated cylinder‚ ruler and water. 2. Take the materials

There is some truth to the statement "what gets measured gets done" with respect to the work environment‚ discuss. I believe the maxim “what gets measured gets done” (accredited to among others‚ Peter Drucker in his 1954 book ’The Practice of Management’) does hold a semblance of truth when associated within the business world. However‚ I would argue that the sentence in itself is incomplete. Between the ‘measuring’ and ‘getting done’‚ mangers need to insert both critical analysis of the measurements

But in that moment I realized‚ I need to prove that I am firm‚ flexible and versatile inany kind of circumstances. And I often showed them my best to make them amazed.

Is displacement a likely outcome of any situational crime prevention initiative? The short answer to this question is no. I will illustrate this answer in more detail by drawing upon three required readings. In his paper‚ Eck (1993‚ pp. 527) explicitly indicated that “there is no evidence of greater than 100% displacement and that full displacement is unlikely.” By summarizing pioneers’ works on the displacement‚ Eck listed six types of displacement: temporal‚ spatial‚ target‚ method‚ crime type

Gentrification causes the rapid increase in property value‚ as well as the eviction of life long tenants‚ and the alterations of whole neighborhoods. On paper‚ it seems like it’s a great idea to take a neighborhood and give it a face lift‚ but there is a human element to the equation we are leaving out. Sternbergh (2009) notes that “Displacement
