An explanation corresponding to the reaction of the cyclic compound β-D- galactose with Cu 2 + solution and its categorization as a reducing sugar is to be stated. Concept introduction: The simplest hydrolyzed form that is obtained from the carbohydrates is known as a monosaccharide. It is a simple sugar. Sugars are of two types, reducing and nonreducing sugars. Reducing sugars are defined as those sugars that contain OH group connected to the anomeric carbon atom. Nonreducing sugars do not contain free OH group to reduce other compounds.

Question

When 15.00 mL of 3.00 M NaOH was mixed in a calorimeter with 12.80 mL of 3.00 M HCl, both initially at room temperature (22.00 C), the temperature increased to 29.30 C. The resultant salt solution had a mass of 27.80 g and a specific heat capacity of 3.74 J/Kg. What is heat capacity of the calorimeter (in J/C)? Note: The molar enthalpy of neutralization per mole of HCl is -55.84 kJ/mol. Which experimental number must be initialled by the Lab TA for the first run of Part 1 of the experiment? a) the heat capacity of the calorimeter b) Mass of sample c) Ti d) The molarity of the HCl e) Tf
