The structure of a disaccharide formed from mannose units joined by a 1→4-a-glycosidic linkage should be drawn. Concept Introduction: Disaccharides are carbohydrates composed of two monosaccharides. Disaccharides are acetals, compounds that contain two alkoxy groups (OR groups) bonded to the same carbon. The reaction between two monosaccharides such that hemiacetal of one reacts with hydroxyl of second, results in the formation of acetal group. The new C-O bond that joins the two rings called a glycosidic linkage. There may be five-membered or six-membered rings in the two monosaccharide. In all the disaccharides there is at least one acetal that joins the rings together. Each ring is numbered beginning at the anomeric carbon, the carbon in each ring bonded to two oxygen atoms

An essential part of the experimental design process is to select appropriate dependent and independent variables. True False

10.00 g of Compound X with molecular formula C₂Hg are burned in a constant-pressure calorimeter containing 40.00 kg of water at 25 °C. The temperature of the water is observed to rise by 2.604 °C. (You may assume all the heat released by the reaction is absorbed by the water, and none by the calorimeter itself.) Calculate the standard heat of formation of Compound X at 25 °C. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

need help not sure what am doing wrong step by step please answer is 971A During the lecture, we calculated the Debye length at physiological salt concentrations and temperature, i.e. at an ionic strength of 150 mM (i.e. 0.150 mol/l) and a temperature of T=310 K. We predicted that electrostatic interactions are effectively screened beyond distances of 8.1 Å in solutions with a physiological salt concentration. What is the Debye length in a sample of distilled water with an ionic strength of 10.0 µM (i.e. 1.00 * 10-5 mol/l)? Assume room temperature, i.e. T= 298 K, and provide your answer as a numerical expression with 3 significant figures in Å (1 Å = 10-10 m).
