Question

calculate the weight of lime obtained by heating 2000kg of 95% pure lime stone (CaCO3)​

Answer 1

Answer:

To calculate:

• weight of lime obtained by heating 2000kg of 95% pure lime stone (CaCO3)

Solution:

100kg impure sample has pure

$CaCO _{}(3) = 95 \\ </p><p> = > 95 kg$

∴ 200kg impure sample has pure

$CaCO _{}(3) = 95 x \frac{200}{100} \\ = > 190 kg$

$CaCO _{}(3) -> CaO + CO log_{}(2 ) \\ since \: 100kg \: CaCO _{}(3) gives \: CaO = 56kg \\ 190kg \: CaCO (3) will \: give \: CaO = \frac{56 \times 190}{100} \\ = > 106.4kg$
