7. Identify as true (T) or false (F): All chemical particles exist in a constant state of random motion. In exothermic reactions, bonds in chemical particles generally become weaker. Matter can change its physical state with pressure alone, at a constant temperature. Dispersion forces work on only some chemical particles.

10. CHALLENGE. Avogadro's number has been determined by about 20 different methods. In one approach, the spacing between ions in an ionic substance is determined by using X-ray diffraction. X-ray diffraction of sodium chloride have shown that the distance between adjacent Na+ and Cl- ions is 2.819 x 10-8 cm. The density of solid NaCl is 2.165 g/cm³. By calculating the molar mass to six significant figures, you can determine Avogadro's number. What value do you obtain? .. .. • Na O cr
