Which of the following is an ionic solid? Os2- SF6 Na2s S8 O so,2-

Use the information provided to calculate the quantity of heat (in kJ) required to convert 59.22 g of substance A from an initial temperature of -8.998ºC to a final temperature of 53.2ºC. The molar mass of the substance is 31.20 g/mol. Melting Point of A = 1.110ºC Heat of fusion = 11.32 kJ/mol Boiling point of A = 109.9ºC Heat of vaporization = 86.91 kJ/mol     Solid Liquid Gas Specific heat (J/gºC) 2.22 4.1 6.4

What are the three basic types of solids and the composite unitsof each? What types of forces hold each type of solid together?
