The standard enthalpy of combustion of benzoic acid is given to be − 3225 kJ / mol . The heat capacity of the bomb calorimeter is to be calculated provided that the temperature increase of 2.16 ° C occurs on combustion of 0.500 g of benzoic acid in the presence of excess O 2 . Concept introduction: The change in enthalpy for complete combustion of one mole of substance in presence of excess oxygen is known as enthalpy of combustion. It is calculated by formula, Δ H comb = q x × M To determine: The heat capacity of the bomb calorimeter.

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
