CaCO3 + 2HNO3 = Ca(NO3)2 + H2O + CO2M(CaCO3)=100 кг/кмольn(CaCO3)=1000/100=10 кмольn(CaCO3)=n(Ca(NO3)2=10 кмольM(Ca(NO3)2=164 кг/кмольm(Ca(NO3)2)=164х10=1640 кг - теорет.выходm(Сa(NO3)2)=0,85х1640=1394 кг - практич.выход

Answer 2

Calculating the Mass of Calcium Nitrate

To calculate the mass of calcium nitrate obtained from the treatment of 1 ton of calcium carbonate with an 85% yield, we can use the following steps:

1. Calculate the Theoretical Yield of Calcium Nitrate - The molar mass of calcium carbonate (CaCO3) is 100.09 g/mol. - The molar mass of calcium nitrate (Ca(NO3)2) is 164.09 g/mol. - The balanced chemical equation for the reaction is: ``` CaCO3 + 2HNO3 → Ca(NO3)2 + CO2 + H2O ``` - Using the molar masses and the balanced chemical equation, we can calculate the theoretical yield of calcium nitrate.

2. Calculate the Actual Yield of Calcium Nitrate - The actual yield is given as 85% of the theoretical yield.

3. Find the Mass of Calcium Nitrate - Using the actual yield, we can calculate the mass of calcium nitrate obtained.
