The given chemical reactions should be identified as exothermic and endothermic. Concept Introduction : An exothermic reaction can be defined as the chemical reaction which releases energy during the formation of product therefore the energy value must be written with product molecules in the balance chemical reaction. An endothermic reaction can be defined as the chemical reaction which absorbs energy during the formation of product therefore the energy value must be written with reactant molecules in the balance chemical reaction.

3) The following molecule, chloral is a common precursor to chloral hydrate, an acetal type molecule that was a first-generation anesthetic. Draw a mechanism that accounts for tis formation and speculate why it does not require the use of an acid catalyst, like most hemiacetal and acetal reaction: (10 pts) H H₂O

You are a Quality Manager for a very well-known food ingredient company that produces umami powder, and you are responsible for setting specification limits. The net weight (in grams) of bags of unami powder is monitored by taking samples of six bags on an hourly basis during production. The label on every bag reports a contents of 1KG umami powder. The process mean is μ = 1012 g, and when the process is properly adjusted, it varies with σ = 11 g. QUESTION: Your organisation strives to ensure that >99.97% of bags of umami powder produced conforms to specification. What performance process index value is required to achieve this process yield? Calculate PPK using the following formula: Ppk = (USL – mean)/3 σ Ppk = (mean -LSL)/ 3 σ
