    I don't know how to answer 28. Alloys may be mixtures, they may form eutectic mixtures (which have compositions like compounds), or they may be solid solutions. I suppose the answer to this question is C.
    For 38, alpha rays are not rays at all, but helium nuclei. Beta rays are not rays but electrons. Gamma rays are electromagnetic radiation.
