Chapter 8, Question 49 x Your answer is incorrect. Try again. In the unit cell of lithium sulphide, the sulphide ions adopt a face-centred cubic lattice. The lithium ions are in the holes within the face-centred cube. If the unit cell is charge-neutral, how many complete lithium ions must be packed within each face-centred cube? complete lithium ion(s) exact number, no tolerance Click if you would like to Show Work for this question: Open Show Work

1 pts D Question 8 Why isn't lattice energy measured for covalent compounds? Covalent compounds form a lattice that is different than ionic compounds and thus another measure is used. Covalent compounds don't form the lattice structure that ionic compounds do. Covalent compounds do not satisfy the octet rule and thus do not have lattice energies. OCovalent compounds have high lattice energies and cannot be measured. Question 9 1 pts Which of the following ionic...

A diffracted -ray beam is observed from the (220) planes of lithium at a 2 angle of 76.8° when -rays of 0.15418 wavelength are used. Calculate the lattice parameter of the lithium. (Enter your answer to three significant figures.)
8. A student conducts an experiment to determine the enthalpy of solution for lithium chloride dissolved in water. The student combines 5.00 grams of lithium chloride with 100.0 ml of distilled water. The initial temperature of the water is 23.0 °C and the highest temperature after mixing reaches 33.0 °C. Assume a density of 1.00 g.ml and a specific heat of 4.18 J/gºC. a. Is the reaction endothermic or exothermic? Justify your answer. b. Calculate the temperature change of the...
