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.
Compound is not a type of mixture. It is a pure substance made up of two or more different elements chemically combined.

A suspension has large particles that settle out on standing.
Copper is an element, as it is a pure substance made up of only copper atoms.
suspension
compound
heterogenous
yes
Potassium hydroxide is a chemical compound.
Colloid has larger particles compared to solution, but smaller than suspension. Therefore, of the three options listed (compound, colloid, suspension), a compound mixture typically has the smallest particles.
Compound is not a type of mixture. It is a pure substance made up of two or more different elements chemically combined.
Vinegar is a homogeneous mixture of water and acetic acid.
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.
no its a heterogeneous

A colloid is not a single compound; it is a mixture with properties between those of a solution and fine suspension.
They create either a suspension, solution, mixture, or a compound.
