In chemistry, a compound is defined as a substance formed by chemical union of two or more elements or ingredients in definite proportion by weight. To answer your question, the marbles themselves are a made of a mixture of a compounds. The marble collection itself is not a compound.
calcium
The scientific name for marble chips is calcium carbonate, which is a chemical compound with the formula CaCO3.
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. Many of the "fine chemicals" that you would find in jars in your school laboratory would have a similar purity to a good quality marble. So 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.
The mineral made up of a calcium compound and commonly found in marble is called calcite. Calcite is a carbonate mineral composed of calcium carbonate (CaCO3) and is often the main component of marble, providing its characteristic white color.
YES!!! It is a compound at any temperature up to approximately1000K, where upon it undergoes thermal decomposition to form Calcium Oxide (CaO)/(Lime) and carbon dioxide (CO2).
YES!!! It is a form of calcium carbonate (CaCO3). Hence it is a compound of calcium.
It's a mixture.

No, because marble is not an element. It is a compound containing Calcium, Carbon and Oxygen. It has the chemical formula CaCO3.
Yes, the compound word 'rock collection' is the noun in the sentence. The noun 'rock collection' is a word for a thing.
Marble is known as Calcium Carbonate (CaCO3) in terms of chemical formula.
