A coffee-cup calorimetry experiment was performed to determine the heat of neutralization for the reaction HCI (aq) + NaOH (aq) → NaCI (aq) + H2O (1) AH = ??? The researchers placed 0.0592 moles of HCl in the calorimeter, with an equivalent mole amount of NaOH. The total volume of the solution after mixing was 90.00 mL (assumed equivalent to 90.00 g). When the reactants were mixed, the temperature of the solution rose by 8.52° C. They assumed the specific heat capacity was identical to water (4.184 What should the researchers report as the AH for this reaction, in units of Report your answer to three sig figs, but do not include units. If your answer is a negative value, be sure to include the negative sign.
Carbohydrates
Carbohydrates are the organic compounds that are obtained in foods and living matters in the shape of sugars, cellulose, and starch. The general formula of carbohydrates is Cn(H2O)2. The ratio of H and O present in carbohydrates is identical to water.
Starch
Starch is a polysaccharide carbohydrate that belongs to the category of polysaccharide carbohydrates.
Mutarotation
The rotation of a particular structure of the chiral compound because of the epimerization is called mutarotation. It is the repercussion of the ring chain tautomerism. In terms of glucose, this can be defined as the modification in the equilibrium of the α- and β- glucose anomers upon its dissolution in the solvent water. This process is usually seen in the chemistry of carbohydrates.
L Sugar
A chemical compound that is represented with a molecular formula C6H12O6 is called L-(-) sugar. At the carbon’s 5th position, the hydroxyl group is placed to the compound’s left and therefore the sugar is represented as L(-)-sugar. It is capable of rotating the polarized light’s plane in the direction anticlockwise. L isomers are one of the 2 isomers formed by the configurational stereochemistry of the carbohydrates.
