40Born-Haber cycle The magnitude of the lattice energy dominates this multistepprocess. Charge on the ions. Chemistry The Central Science Chapter 8 Section 2 For NaCl the lattice dissociation enthalpy is 787 kJ mol -1. . Lattice energy cannot be measured empirically but it can be calculated using electrostatics or estimated using the Born-Haber cycle. Nag Cl-g NaCls Ho -7873 kJmol. Chemistry questions and answers. Part A Which set of compounds is arranged in order of increasing magnitude of lattice energy. The lattice energy formula of an equivalent ionic solid could be determined with the help of a revised formula of Coulombs law. Therefore CaO has the largest lattice energy because its product of ionic charges is q1q2224 which is greater in magnitude than that of the other two ionic compounds where q1q21. This would denote that the ionic compound with the charge of -3 exhibits a much higher lattice energ...
Correlation is a measure of the direction and strength of the linear straight-line association between two quantitative variables. Which statement best describes the association between variable X and variable Y. Correlation Analysis A group of students did an experiment to see how drinking cups of coffee right before bed affected sleep. . The sign of the correlation tells us the direction of the association. Perfect negative association B. Perfect negative association strong negative association. 785 students attemted this question. The results are shown below in the scatter plot with a line of best fit. Terms in this set 53 sample correlation coefficient. It is always between negative 1 and 1. If our data in a scatterplot is straight enough we can model our data with a _____. Which best describes the association between variables x and y. Correct answer to the question Which statement be...
