Chemical Symbol Of Marble

Caco3 calcium carbonate is the chemical formula for marble what is the correct chemical name for limestone or marble.

Chemical symbol of marble.

Limestone crystals are much smaller than that of marble and limestone is much more porous. Sodium hypochlorite is a chlorine compound often used as a disinfectant or a bleaching agent. Limestone and marble are predominately made of the mineral calcite caco3. The specific gravity of marble is the ratio of the density of marble to that of a reference substance usually water.

Marble is made of calcium carbonate caco3 which is also what limestone is made from. Typically marble is composed of the following major constituents. The exact chemical composition of marble will greatly vary dependong on the location and the minerals or impurities present in the limestone during recrystallization. A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule using chemical element symbols numbers and sometimes also other symbols such as parentheses dashes brackets commas and plus and minus signs.

Chemical components of marble lime cao 28 32 silica sio2 3 30 varies with variety mgo 20 to 25 feo fe2o3 1 3 5. This information can be used to tell whether marble will float or sink if dropped in water buoyancy. The only difference between limestone and marble is the crystalline structure. Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite marble is typically not foliated although there are exceptions in geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone.

Physical properties of marble hardness 3 to 4 on moh s scale density 2 55 to 2 7 kg cm3 modulus of rupture 12 to 18 n mm2 compressive strength 70 to 140 n mm2 water absorption less than 0 5 except rainforest green brown. Calcium carbonate is a chemical compound with the formula ca co 3 it is a common substance found in rocks as the minerals calcite and aragonite most notably as limestone which is a type of sedimentary rock consisting mainly of calcite and is the main component of pearls and the shells of marine organisms snails and eggs calcium carbonate is the active ingredient in agricultural lime and. In its pure form marble is a white stone with a crystalline and sugary appearance consisting of calcium carbonate caco 3 usually marble contains other minerals including quartz graphite pyrite and iron oxides these minerals can give marble a pink brown gray green or variegated coloration. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat.
