Answer
Classifying each of the following as an element, a compound, or a mixture:
a. neon gas in lights- element
b. a salad dressing of oil and vinegar- mixture
c. sodium hypochlorite (NaOCl) in bleach- compound
Work Step by Step
a. neon gas in lights- neon atoms are the only ones present and hence it is an element.
b. a salad dressing of oil and vinegar- oil and vinegar do not mix very easily and hence this is a mixture.
c. sodium hypochlorite (NaOCl) in bleach- in sodium hypochlorite Na (sodium), O (oxygen), and Cl (chlorine) atoms are chemically combined in the same proportion (1:1:1). Hence this is a compound.
