20. Methyl orange is an indicator with a \( K_a \) of \( 1 \times 10^{-4} \). Its acid form, HIn, is red, while its base form, In⁻, is yellow. At pH 6.0, the indicator will be (A)red (B)orange (C)yellow (D)blue (E)not enough information

10. The kinetic-molecular theory of gases does not assume that (A)gases are made up of tiny particles in constant chaotic motion (B)gas particles are very small compared to the average distance between the particles (C)gas particles collide with the walls of their container in elastic collisions (D)the average velocity of gas particles is directly proportional to the absolute temperature (E)all of these are correct
