Interpretation: The correct description that identifies zinc as a compound, element, the heterogeneous or homogeneous mixture should be determined.
Concept Introduction: The simplest form of matter consisting unique set of properties is said to be elements. They are pure substances made up of only one type of atom.
The chemical combination of two or more elements in a fixed proportion results in the formation of a compound.
A mixture is said to be homogenous when its composition is uniform throughout whereas a mixture is said to be heterogenous when its composition is not uniform throughout.

- Draw and show the full mechanism of how the molecule ((1E, 3E, 5E)-1-methoxyhepta-1,3,5-triene) is built using substitution and elimination reactions. You can start with an alkane of any carbon length with any number of leaving groups attached or with a alkoxide of any carbon length (conjugate base of an alcohol). Show each step and and explanation for each reaction. Also include why the reagents and solvents were picked and what other products can be expected.arrow_forwardDon't USE AIarrow_forwardDon't USE AIarrow_forward
