Concept introduction:
All matter can exist in mainly three states; solid, liquid and gases. Here, solids can be further classified in different types based on their structural units. The structural units can be constituent atoms or molecules or ions. Such as ionic solids are composed of ions, whereas metallic solids are composed of metal ions and electrons. A covalent solid consists of covalent molecules in it. Hence, one can easily identify the structural units with the help of type of solids and vice-versa.

- Identify and provide a concise explanation of a specific analytical instrument capable of detecting and quantifying trace compounds in food samples. Emphasise the instrumental capabilities relevant to trace compound analysis in the nominated food. Include the specific application name (eg: identification and quantification of mercury in salmon), outline a brief description of sample preparation procedures, and provide a summary of the obtained results from the analytical process.arrow_forwardIdentify and provide an explanation of what 'Seperation Science' is. Also describe its importance with the respect to the chemical analysis of food. Provide specific examples.arrow_forward5. Propose a Synthesis for the molecule below. You may use any starting materials containing 6 carbons or less (reagents that aren't incorporated into the final molecule such as PhзP do not count towards this total, and the starting material can have whatever non-carbon functional groups you want), and any of the reactions you have learned so far in organic chemistry I, II, and III. Your final answer should show each step separately, with intermediates and conditions clearly drawn. H3C CH3arrow_forward
