state at least three problems that may be involved when using flame tests for identification purposes
three problems are
1.If the platinum wire or sample contains impurities then result of test must gone wrong.
2.if the ion have low concentration flame test does not valid.
3.flame test is not valid for such ions which have higher lattice energy. cannot detect Fe3+ confirmedly by flame test.

Discuss some of the problems that may occur when requirements must be elicited from three or four different customers
Identify at least three torts or crimes that Mark Zuckerberg may have committed when he created the Facemash website. (Your essay should contain at least 500 words.)
Describe at least three potential problems global businesses face when they outsource or subcontract their work to companies in other countries? (e.g., a U.S. sneaker company outsourcing the manufacturing of its sneakers to a separate company in China or Vietnam.) (do not answer) How do you deal with the security issue and confidentiality issues? (answer this)

PROBLEMS 2.32 The wavefunction for a particle in one dimension is given by Another state that the particle may be in is A third state the particle may be in is y2/4 Normalize all three states in the interval-oo < y <-co (i.e., find A1,A2, and A3) is the probability of finding the particle in the interval 0 y < 1 when the particle : is in the state vs the same as the sum of the separate probabilities for...
1) Identify audit tests that may be used as alternative audit procedures when a response is not received for a positive confirmation request. Compare and contrast the quality of audit evidence yielded by these procedures with that produced by audit confirmation procedures. 2) Is it appropriate for audit firms to sharply discount their professional fees for development stage companies? Why or why not? What problems, if any, may this practice pose for audit firms? 3) Should audit firms accept “ethically...
Define discretionary measures and automatic stabilisers. Give examples. State the problems policy-makers face when using discretionary policy measures. Discuss the advantages of “automatic stabilisers” over “discretionary measures
when a solid dissolves in water, heat may be involved or absorbed. The heat of dissolution can be determined using a coffee cup calorimeter. In the laboratory a general chemistry student finds that when 1.16 g of CaCl2 (s) are dissolved in 116.30 g of water, the temperature of the solution increases from 23.65 to 25.44 °C. The heat capacity of the calorimeter was determined in a separate experiment to be 1.76 J/degrees Celsius. Based on the students observation, calculate...
