Question

Bord atoms 4) Which of the following represents a physical property? 4) A) Mercury is a silvery liquid at room temperature. B) Iron has a tendency to "rust." C) Xenon has an unreactive nature. D) Butane is highly flammable. E) Sodium metal is extremely reactive with chlorine gas. 5) 5) Which of the following statements is TRUE? A) At low temperatures, intermolecular forces become important and the pressure of a gas will be lower than predicted by the ideal gas law. B) The smaller a gas particle, the slower it will effuse At a given temperature, lighter gas particles travel more slowly than heavier gas particles. e higher the temperature, the lower the average kinetic energy of the sample. E) None of the above statements is true. 6) 6) Which molecule or compound below contains an ionic bond? B) C2Br4 C) CS2 D) oCl2 E) NH4NO3 A) SiF4

Explanation / Answer

4)

The one in which there is change in shape,size,phase or volume etc and can be retraced with simple change in temperature and pressure alone is called a physical property.

ans = (A) mercury is silvery liquid at room temperature

5)

ans = (A)

6)

ans = (E) NH4NO3 is ionic
