Question

Is marble an element compound or a mixture

Answer 1

This is a very simple question that has a rather complicated answer. Marble is typically more than 95% calcium carbonate, perhaps even 99% calcium carbonate, and calcium carbonate is a compound. Marble has a good claim to be recognised as a compound. 
However, if you look at a piece of marble, it has numerous very pretty stripes and blotches -- often known as "marbling" even. Clearly marble is not a homogeneous material. The small amount of various impurities in marble produce its very pretty appearance. So marble must also be recognised as a mixture.

Answer 2

Answer:n

Marble is a mixture.

Explanation:

Because marble are not homogeneous and therefore not pure substances or compounds. They are called mixtures. Mixtures are defined as matter which consists of two or more substances mixed together. A mixture can be either homogeneous or heterogeneous.
