Most of the raw materials occurring over the earth consist of innumerable elemental impurities. These impurities should be removed through various industrial processing. In some cases, it is not economically feasible to remove such minor impurities completely as they do not show any effect on the quality of the final product.

Summary Introduction

Most of the raw materials occurring over the earth consist of innumerable elemental impurities. These impurities should be removed through various industrial processing. In some cases, it is not economically feasible to remove such minor impurities completely as they do not show any effect on the quality of the final product.

Expert Solution & Answer

Answer to Problem 1RQ

Correct answer: The presence of trace elements in materials provides useful “invisible” markers when comparing physical evidence.

Explanation of Solution

Crime investigators use the trace elements as they behave as “invisible markers” that can provide data for comparison or can help in establishing the material source. For example, glass fragments can be used as valuable trace evidence. Forensic investigators have also utilized the evidential values of different trace elements present in fibers, paint and soil.

Hence, trace elements can provide useful markers for comparing the physical evidence.

An 1100 pound equine patient was given 20 mg/kg sucralfate 3 times a day, 2.8 mg/kg famotidine twice a day, and 10mg/kg doxycycline twice a day. Sucralfate comes as a 1 gm tablet, famotidine as 20 mg tablets, and doxycycline as 100mg tablets. All are in bottles of 100 tablets.How many total mg are needed for the patient and how many tablets of each would be needed to provide each dose?How many bottles of each would be needed to have available if this patient were to be on this drug regimen for 5 days?

The patient needs a solution of 2.5% dextrose in Lactated Ringer’s solution to run at 75 ml/hr for at least the next 12hours. LRS comes in fluid bags of 500 ml, 1 Liter, 3 Liters and 5 Liters. How can a 2.5% solution be made by adding50% dextrose to the LRS?
