Sand is made form a mixture of mineral grains (mainly quartz or calcite) which are themselves compounds. If there is water or air flowing though the sand at a fast rate, then it can also be a suspension.
Filtered maple syrup is a solution.
An element is an element and can not, in anyway, be separated.
Sand is a mixture and rarely is only one compound.
heterogenous
Mercury is an element; its symbol is Hg. You can find it on the Periodic Table of Elements in the transition state section.

compound
i think is an solution

Ca is the chemical symbol for calcium, an element. It is an alkali metal with atomic number 20. ------------------------------------------- The above is true, however if the element Ca is present in a solution then it will be present as part of an Ionic compound in solution, note a solution is not a mixture, element or compound, it is a SOLUTION. An insoluble compound of Ca could be present in liquid, in which case you would have a suspension. A suspension is a mixture.

Salt is a compound because it is composed of sodium and chloride ions that are chemically bonded together in a fixed ratio. It is not an element, suspension, heterogeneous mixture, homogeneous mixture, or colloid.
Copper is an element, as it is a pure substance made up of only copper atoms.
Mercury is an element; its symbol is Hg. You can find it on the Periodic Table of Elements in the transition state section.
no its a heterogeneous
