    • D.

      Neutralization of stomach acid with an antacid

    • E.

      Lead becomes a liquid when heated to 601C

    when sulfuric acid corrodes something it turns it into something else- that's chemical
    when cyanide is ingested it causes a chemical change in the patient
    gasoline combines with oxygen to form carbon dioxide and water- a chemical change
    stomach acid (hydrochloric acid) combines with a base to form salt and water- new substances are formed; this is a chemical change
    when lead melts it simply becomes liquid lead; it is still lead; this is a physical change
