SECTION 2: ANSWER TRUE OR FALSE FOR THE FOLLOWING QUESTIONS (0.5 POINT EACH) 1. Some covalent compounds dissolve in water to produce conducting solutions. 2. In an acid-base (neutralization) reaction the indicator will change color at the end point. 3. In an acid-base (neutralization) reaction the equivalence point is the point where the indicator changes color. 4. A particular reaction may be both a precipitation and an acid-base (neutralization) reaction. 5. In a redox reaction, the reducing agent undergoes loss of electrons. 6. In a redox reaction, the oxidizing agent undergoes loss of electrons. 7. All combustion reactions are classified as combination reactions. 8. The combustion of an element is always a combination reaction. 9. A combination reaction may also be a displacement reaction. 10. For a gas obeying Boyle's Law, a plot of V versus 1/P will give a straight line passing through the origin. 11. For a gas obeying Charles'Law, a plot of V versus 1/T will give a straight line passing through the origin. 12. At a temperature of absolute zero, the volume of an ideal gas is zero. 13. From the postulates of kinetic-molecular theory, it follows that the molecules of all gases at a given temperature have the same average speed. 14. From the postulates of kinetic-molecular theory, it follows that the molecules of all gases at a given temperature have the same average kinetic energy. 15. The average kinetic energy of gas molecules is proportional to the absolute temperature.
