“Alternative dispute resolution (ADR) has become a more viable option than settling disputes at court.
It provides a much cheaper, more accessible and speedier method of dispute resolution”.
Critically explain with cogent examples, how ADR has become increasingly important in resolving
trade disputes in modern business environment.
During a practical session, a good 2nd year Inorganic I student prepared a good quality alum double salt
with the general formula, M2SO4.M’2(SO4)3.24H2O, where M is +1 and M’ is +3 cations. This was
carried out by weighing exactly 1.7418g of potassium sulphate, which was dissolved in 10mL distilled
water (dH2O). Similarly, 6.6644g of Al2(SO4)3.18H2O in the exact same fashion. The dissolved clear
solutions was mixed in a clean evaporating dish and allowed to crystallize out overnight. The crystals
were filtered off, washed with cold water and dried between filter papers. After complete drying the
experimental yield was determined to be 9.0500g with a NANI AnalyticaR analytical balance.
1.1 Answer all questions below after completing and balancing the following chemical equation:
a) K2SO4 + Al2(SO4)3·18H2O + __H2O → K__SO4·Al__(SO4)3·__H2O [4]
b) What is the theoretical yield of the reaction in the experiment narrated above? [7]
c) Determine the percentage yield of this experimental product. [2]
d) Give the chemical formula of an alum without the amphoteric Al trivalent ion, Al3+
. [2]
e) When limited amount of 0.1M NaOH solution is added to 0.1M of the alum product give
precipitate.
(i) What is the identity of the precipitate formed in this reaction? [1]
(ii) Give an explanation for the product in (i) in the form of a balanced equation. [2]
f) In a similar fashion as in e) above, Al2(SO4)3 solution reacts with the hydroxide solution to
produce a precipitate. Give the product by balancing the net ionic equation. [2]
g) To the product in e) above if one adds an excess of the base something peculiar happens. What
do you expect to happen? Explain with a balanced equation! Hint: Al is amphoteric! [2]
1.2 Why is it almost impossible for Al metal to react with water at normal ambient conditions? Give the
chemical formula of the protective coat that forms on the surface of the metal. [4]
1.3 In an experiment 0.3000 g of Al (Mr = 26.982 g/mol) is reacted with 10.00mL of 4.0 M KOH under
ambient conditions; determine the:
(i) limiting reagent [4]
(ii) theoretical yield [2]
Question 2 [16]
Determining the Formula of an Unknown Alkaline Earth Carbonate:
In an experiment of Inorganic I a student weighed accurately 0.2200 g of an unknown group IIA
carbonate (MCO3) sample on the analytical balance into a 250mL Erlenmeyer flask. Pipetted 10.00 mL
of standardized 0.4999M HCl into the flask, swirled the mixture until the reaction until the fizzing
ceased and the sample was completely dissolved. Added 3 drops of bromophenol blue indicator and
titrated with the standardized 0.2000M NaOH solution. Repeated the analysis with two additional
samples to give two more determinations. The average titre volumes for each of the three determinations
was found to be exactly 10.10 mL.
2.1 Balance step-wise with physical states the two respective chemical equations involved in this back-
titration technique reaction. [6]
2.2 Calculate the molar mass of the unknown carbonate, MCO3, identify the M in the sample. [10]
Question 3 [12]
3.1 Assume you carried out an experiment of Na and K metals reacting with water; report briefly what is
likely to happen in both cases. Also, provide the corresponding reaction equations that describe those
reactions. Hint: Consult your Experiment 3b! [4]
3.2 For the two metals above, which is more reactive? How does this trend depict the reactivity of the
elements within the group? Rank them in order of increasing reactivity. [4]
3.3 Write the balanced chemical equation for the reaction of oxygen with sodium to produce the resultant
peroxide? [2]
3.4 With physical states provide the general equation for the reaction between elements of Group VII
(i.e. the halogens) with those of Group I?

Hello,
Your Research Project is due this week. It must consist of:
1. Five source annotated bibliography
2. Slide presentation with 12 or more slides
3. Summary or Abstract containing at least 750 words.
Below is the Topic I selected and submitted as a proposal and got approved by professor.
Vulnerability and Risk assessment:
Cloud computing is an effective delivery model to provide services. It is not a new technology but uses information to deliver services using existing technologies. Vaquero (2009) “Clouds are a large pool of easily usable and accessible virtualized resources (such as hardware, development platforms and/or services). These resources can be dynamically re-configured to adjust to a variable load (scale), allowing also for optimum resource utilization. This pool of resources is typically exploited by a pay-per-use model in which guarantees are offered by the infrastructure Provider by means of customized SLAs”.
When the organizations using the cloud services there are a considerable number of vulnerabilities and risks involved that needs to be assessed and managed to continue using the services without any interruption.
“Vulnerability” refers to a software, hardware, or procedural weakness that may provide an attacker the open door to enter a computer or network and have unauthorized access to resources, within the environment. Vulnerability characterizes the absence or weakness of a safeguard that could be exploited. This vulnerability may be a service running on a server, unpatched applications or operating system software, or an unsecured physical entrance (Kamal, 2011).
A risk is the negative impact on the systems in terms of data storage, data theft by the malicious intruders. The level of risk can be varied based on the type of cloud architecture that is being used. A cloud customer or user can transfer the risk to the cloud services provider and consider it in the cost benefit that’s being received from the services. However, all the risks can’t be transferred to the cloud provider for example if the risk occurred due to the failure of the business then cloud provider or any other third party can’t mitigate the damage or can compensate the expenses for this.
There is a level of risk involved in allocating resources to all the participating firms when using cloud as it is a more demanding service and resources are allocated based on the statistical projections. There are resource allocation algorithms that are used for resource allocation purpose and these are vulnerable to distortions of fairness. There are risks of service being unavailable when a particular application uses a specific resource very intensively. When the service provider is not able to meet, due to this economic and reputational loss can occur to the cloud provider. There are risks when access controls and permissions are compromised and it can lead to loss of data of the customers and so financial loss to the organizations. Also, this can put the company’s confidential and PII data at risk.
Computing capacity, storage, and network are shared between multiple users. This class of risks includes the failure of mechanisms separating storage, memory, routing, and even reputation between different tenants of the shared infrastructure (e.g., so-called guest-hopping attacks, SQL injection attacks exposing multiple customers’ data stored in the same table, and side channel attacks). Insider attacks are considered to be a high risk as it can impact the confidential data and can impact the organization’s reputation, customer trust and experiences of all the employees.

Assignment Overview
Like many airlines around the world, leading Australian airline Qantas is facing very difficult times in spite of having a 65% market share in its home market of Australia. Due to rising fuel costs and a slow world economy, Qantas has recently been losing money and their CEO Alan Joyce has some tough choices to make.
One difficult decision for Joyce is whether or not to sell Qantas’ frequent flyer program. It may seem odd for an airline to sell its frequent flyer program, but Qantas’ program is much more than just an airline reward program. Members of this program can gain points not only by flying on Qantas but also through other means such as shopping at one of Qantas’ corporate partners or using one of their credit cards. Points can be redeemed not only with free flights, but also with products from numerous retailers. Over 10 million Australians belong to this rewards program, almost half of the population.
The frequent flyer program is Qantas’ most valuable asset and a sale of this program would help Qantas get out of its current financial troubles. However, selling the program would also mean allowing another company to have access to Qantas most loyal customers including their business class and first class customers. In the long-run, there is potential the sale could backfire and would not be wise.
Do some research on CEO Joyce’s current choice of whether or not to sell their frequent flyer program, and also thoroughly review the background materials on intuitive versus rational decision-making including Buhler (2001) and Kourdi (2011). Your assignment will be to apply the background materials concepts to Joyce’s current big decision.
