What is the grams of substance in 4.5 moles CaCO3?
To find the grams of CaCO3 in 4.5 moles, you would first calculate the molar mass of CaCO3 (40.08 g/mol for Ca, 12.01 g/mol for C, and 16.00 g/mol for O), which totals 100.09 g/mol. Then, multiply this molar mass by the number of moles (4.5) to get the grams of CaCO3. So, 4.5 moles of CaCO3 is equivalent to 450.405 grams.
Formula of limestone?
The formula for limestone is CaCO3, which represents calcium carbonate. It is a sedimentary rock that is composed mainly of the mineral calcite.
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 .
What will happen after heating CaCO3?
CaCo3=Cao+Co2
Is CaCo3 insolube in water?
CaCO3 is insoluble in water.
How do you balance CaCO3 ----- CaO CO2?
the answer is DECOMPOSITION... and that is the answer not CaCO3
How many moles are there in 250 g of CaCO3?
To find the number of moles in 250 g of CaCO3, divide the given mass by the molar mass of CaCO3. The molar mass of CaCO3 is 100.09 g/mol. So, 250 g ÷ 100.09 g/mol ≈ 2.50 moles of CaCO3.
What is the mass of CaCO3?
Molar mass of CaCO3 = 100.0869 g/mol
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 is the balanced equation for caCO3 2HCI?
CaCO3 + 2HCl --> CaCl2 + H2O + CO2
How many o atoms are present in 50gram of caco3?
There are 2 oxygen atoms in one molecule of CaCO3. To calculate the number of oxygen atoms in 50 grams of CaCO3, you first need to find the number of moles of CaCO3 using its molar mass. Then, multiply the number of moles by the number of atoms of oxygen per molecule of CaCO3 (2) to find the total number of oxygen atoms.
What is the coefficient for na2co3 cacl2 caco3 nacl?
The balanced chemical equation for the reaction between Na2CO3 and CaCl2 to form CaCO3 and NaCl is: Na2CO3 + CaCl2 -> CaCO3 + 2NaCl. Therefore, the coefficients are 1, 1, 1, and 2 for Na2CO3, CaCl2, CaCO3, and NaCl respectively.
