Carbon dioxide.
Mainly calcium carbonate.
CaCO3 (Calcium Carbonate)
The streaks produced in marbles are a product of the impurities present in the sedimentary carbonate rocks such as silt durring metamorphisis.
The number of marbles in 3 moles will depend on the molar mass of the marbles. To calculate this, you need to know the molar mass of the type of marble you are referring to (for example, regular glass marbles have a molar mass of about 24 grams/mol). Then you can use Avogadro's number to convert moles to the actual number of marbles.
He will have 13 blue marbles and 10 green marbles.
10 Green marbles, 13 Blue marbles.
He has 10 green marbles.
Marbles are naturally produced by nature, hence, a marble is a non-foliated metamorphic rock composed of recrystallized carbonate minerals, most commonly calciteor dolomite (wikipedia). However, marbles have been used as building materials during construction, and so men do play a part in shaping these marbles into ones we frequently see as walls or floors tiles in buildings.
