The Effect of Different Isotopes on Atomic Mass Introduction: An isotope is a variation of an atom that already exists. An isotope is different from an atom because of the number of neutrons in its nucleus. Finding the amount of neutrons in an atom can be calculated by subtracting the atomic number of a specific atom from its atomic mass. When looking at the periodic […]
Calibration Curve Equation: y = 984 371. 3561x + 216 064. 755 R2 = 0. 9912 Calibration Curve Equation: y = 688 260. 8175x + 475 029. 6892 R2 = 0. 9766 The peak areas of the acids were then obtained through chromatograms and plotted against the concentrations of the standard solutions of the organic acids to construct a calibration curve. Finally, the calibration curves obtained were used to determine the concentration of the organic acids in samples of white […]
3. 1 & 3. 2 Chemistry Notes Dalton * In 1805, John Dalton reintroduced the idea to explain 3 fundamental principles Experimental Work * Atoms of different elements have different properties * Law of definite proportion and multiple compositions: atoms of 2 or more elements can combine in a fixed ratio to form new substances depending on their combining capacities (eg. H2O vs H2O2) * […]
The first semester of the two part series covers the topics chemistry, histology, genetics and inheritance, and the integument, skeletal, muscular, digestive, and reproductive systems. General objectives: 1. To discuss a basic understanding and working knowledge of the human body. 2. To outline the concepts of homeostasis and interdependence of all body systems. 3. To provide an Introduction to the disruption of homeostasis (pathology) as […]
