What mass of calcium oxide will be obtained by heating 3mol of CaCO3?

168 g
168 g mass of CaO will be obtained by heating 3 mole of CaCO3 [Atomic mass of Ca = 40]. Explanation :- 3CaCO2 ⎯→ 3CaO + 3CO2 ∴ Molecular mass of CaO is = 40 + 16 = 56 ∵ 3CaO is formed in the reaction. ∴ 3 × 56 = 168 g of CaO is formed.

How much volume of CO2 is produced when 50g of CaCO3 is heated completely under standard conditions?

Hence, at STP, ${ 11.2L }$ of carbon dioxide is obtained by thermal decomposition of ${ 50g }$ of calcium carbonate.

What mass of calcium oxide is formed when 10g of calcium carbonate is completely decomposed?

5.6 g
Using conservation of mass 10 g of calcium carbonate produces 5.6 g of calcium oxide.

What is the mass of calcium oxide?

56.0774 g/mol
Calcium oxide/Molar mass

What mass of CaO will be obtained by heating 5 moles of CaCO3?

Here is your answer. As 1 mole of Caclium carbonate on decomposition yields only 1 mole of CaO therefore, 5 mole of CaCO3 will also form 5 mole of CaO. Hence, 280g of CaO will be obtained by the decomposition of 5 mol of CaCO3.

What mass of calcium oxide is produced when 10g of calcium carbonate is heated?

When calcium carbonate is heated it turns into calcium oxide and carbon dioxide. 10 g of calcium carbonate produces 5.6 g of calcium oxide.

What will be the volume of CO2 produced by heating 0.25 g of CaCO3?

Therefore 25 g of CaCO3 gives 44/100 * 25 = 11 grams. One mole of CO2 is 44 grams. Therefore in 11 grams of CO2 , there would be 1/44 * 11 = 0.25 moles. 5.6 L of volume.

What is the mass of 50g of CaCO3 and CO2?

The first thing to do here is to calculate the relative formula mass of CaCO 3 and CO 2. The decomposition equation shows 1 CaCO 3 goes to 1 CaO and 1 CO 2. We have 50 g of CaCO 3, effectively we have half a CaCO 3. In order to get the mass of CO 2 we need to times the RFM of CO 2 by 0.5 (or divide by 2) because of the ratio of CaCO 3 to CO 2:

How do you convert Cao to CO2 from CaCO3?

CaCO3 → CaO + CO2. 1 mole of CaCO3 is able to yield 1 mole CO2. 3 moles of CaCO3 is able to yield 3 moles of CO2. 3 moles of CaO is equivalent to 3x molar mass of CaO.

How do you calculate the mass of CO2 from the RFM?

In order to get the mass of CO 2 we need to times the RFM of CO 2 by 0.5 (or divide by 2) because of the ratio of CaCO 3 to CO 2: 22 g of CO 2 are obtained from decomposition of 50 g of CaCO 3. Need help with Chemistry?

What is the mass of 56G of Cao in kJ?

Change in Enthalpy: ΔH (1000C) = +163.2kJ (positive, so the reaction is endothermic) This reaction produces 1mol CaO, mass = 56.077g 100 gm CaCo3 means 1 mole CaCo3 as molecular mass is 100. Mass = 56g/mol CaO / 100g/mol CaCO3 * 100g CaCO3 = 56g CaO produced.
