I NEED HELP PLEASE, THANKS :)

Explain the difference between a homogeneous mixture and a heterogeneous mixture. Give an example of each.

Read below.

Explanation:

Definition of a homogenous mixture:

"A homogeneous mixture is a solid, liquid, or gaseous mixture that has the same proportions of its components throughout any given sample." -Wikipedia

Definition of a heterogeneous mixture:

"A heterogeneous mixture has components in which proportions vary throughout the sample." -Wikipedia

So the difference is that heterogenous mixture's components may differ while a homogeneous mixture's components have the same proportions.

Example of a homogenous mixture: Water ()

Example of a heterogeneous mixture: Trail Mix

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
