You work in a research organization that is looking for markers of various diseases that can be used as a diagnostic for the disease. It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu. What instrument would you recommend purchasing to support this work, Atomic absorption spectrophotometer or an inductively coupled plasma atomic spectrophotometer? Explain the basis for your decision.

Why is this correct?

Given the following data: Pals) 6 Cl2(g) → 4PCI3(g) AH = -1225.6 kJ Pals) 5 O2(9) > P4010(5) AH = -2967.3 kJ PCI3(9) Cl2(g) → PCI5(g) AH = -84.2 kJ PCI3(g) Oz(g) → CI3PO(g) AH = -285.7 kJ 2 Calculate AH for the reaction P.O10(s) + 6 PCI5(g) → 10 CI3PO(g)

Fertilizer X is a complete fertilizer with a fertilizer grade of 25-25-25, it is the only fertilizer material needed to satisfy a recommendation of 120-50-60 kg/ha; (b) Fertilizer X (25-25-25), Fertilizer Y (0-0-62) and fertilizer z (0-50-0) are the fertilizer materials needed to satisfy a recommendation of 120-50-60 kg/ha.   2. (a) a recommendation of 80-80-80 kg/ha is satisfied with 53 kg of fertilizer X (15-15-15)/ha; (b) the same recommendation (80-80-80) is satisfied by applying 0.4 g of fertilizer X to a 15 kg soil in a clay pot. 3. (a) Lower fertilizer analysis implies higher amounts of the fertilizer material needed to be applied to satisfy a recommendation. (b) Fertilizer analysis or grade is expressed as %N-%P-%K, and is usually printed on the fertilizer container/sack/pack 4. (a) Under acidic conditions, all of the plant…
