What is the grams of substance in 4.5 moles CaCO3?
Molar mass of CaCO3 = 66.1221g CaCO3/mole CaCO3. This means that 1 mole CaCO3 = 66.1221g CaCO3. To find the mass of 4.5 mole CaCO3, complete the following calculation: 4.5g CaCO3 X 1mol CaCO3/66.1221g CaCO3 = 0.068 mole CaCO3.
What is the chemical formula of chalk?
Chalk is CaCO3. The chemical name for chalk is calcium carbonate. It is a porous sedimentary rock, and is also a type of limestone. The White Cliffs of Dover are actually made from chalk.
How many moles are there in 250 g of CaCO3?
250 grams CaCO3 (1 mole CaCO3/100.09 grams) = 2.50 moles of calcium carbonate
What type of atom is caco3?
CaCO3 is achemical compound and contains three different elents, calcium carbon and oxygen. It is ionic and the chemical formula is the formula unit.
How many atoms of oxygen are in three molecules of CaCO3?
Three molecules of calcium carbonate (CaCO3) has nine(9) oxygens. Think of 3CaCO3 = CaCO3 + CaCO3 + CaCO3. Each molecule of CaCO3 has ;- 1 atoms of calcium (Ca) 1 atom of carbon (C) 3 atoms of oxygen (O3 = O + O + O). So if one molecules of CaCO3 has 3 oxygens, then three molecules of CaCO3 has 3 x 3 = 9 oxygens. The answer!!!!!
What material makes an exoskeleton?
Chitin.
What type of material is Limestone?
It is a carbonate sedimentary rock, composed of precipitated calcite or shells and shell fragments composed mainly of calcite, calcite being composed of CaCO3.
Is marble a smooth and contains shiny crystals?
Marble (with the chemical formula CaCO3) is a crystalline material.
What is the grams of substance in 4.5 moles CaCO3?
Molar mass of CaCO3 = 66.1221g CaCO3/mole CaCO3. This means that 1 mole CaCO3 = 66.1221g CaCO3. To find the mass of 4.5 mole CaCO3, complete the following calculation: 4.5g CaCO3 X 1mol CaCO3/66.1221g CaCO3 = 0.068 mole CaCO3.
Formula of limestone?
It is CaCO3.....it is the same as marbleFormula: CaCO3
What is the chemical formula of chalk?
Chalk is CaCO3. The chemical name for chalk is calcium carbonate. It is a porous sedimentary rock, and is also a type of limestone. The White Cliffs of Dover are actually made from chalk.
Is caco3 insoluble when react with water?
caco3 is solid form. its density is high so caco3 is not soluble in water. but co2 mix in water befuor the mix in caco3 . so caco3 is soluble after mixing the co2 .
How do you balance CaCO3 ----- CaO CO2?
the answer is DECOMPOSITION... and that is the answer not CaCO3
What is CaCO3?
CaCO3 is the chemical formula for calcium carbonate.
Is CaCo3 insolube in water?
CaCO3 is insoluble in water.
What will happen after heating CaCO3?
CaCo3=Cao+Co2
A type of rock that is very badly affected by acid rain?
For example limestone which is calcium carbonate (CaCO3).
