The reason for why there is a high barrier to rotation arround a carbon–carbon double bond than carbon–carbon single bond has to be explained Concept introduction: In Orbital overlap model of bonding , two nuclei’s of two atoms are approach each other and overlap their atomic orbitals. As the overlapping the energy increases, the interaction decreases. After some distance the minimum energy is reached and it corresponds to the bonding distance. The two atoms of nuclei begin to repel and energy increases. There is a high barrier to rotation arround a carbon –carbon double bond than carbon-carbon single bond because higher energy require to break the pi-bond than the sigma bond.

There is an instrument in Johnson 334 that measures total-reflectance x-ray fluorescence (TXRF) to do elemental analysis (i.e., determine what elements are present in a sample). A researcher is preparing a to measure calcium content in a series of well water samples by TXRF with an internal standard of vanadium (atomic symbol: V). She has prepared a series of standard solutions to ensure a linear instrument response over the expected Ca concentration range of 40-80 ppm. The concentrations of Ca and V (ppm) and the instrument response (peak area, arbitrary units) are shown below. Also included is a sample spectrum. Equation 1 describes the response factor, K, relating the analyte signal (SA) and the standard signal (SIS) to their respective concentrations (CA and CIS).

A mixture of 0.568 M H₂O, 0.438 M Cl₂O, and 0.710 M HClO are enclosed in a vessel at 25 °C. H₂O(g) + C₁₂O(g) = 2 HOCl(g) K = 0.0900 at 25°C с Calculate the equilibrium concentrations of each gas at 25 °C. [H₂O]= [C₁₂O]= [HOCI]= M Σ M

What units (if any) does the response factor (K) have? Does the response factor (K) depend upon how the concentration is expressed (e.g. molarity, ppm, ppb, etc.)?
