Question

masa calcar =18.56 kg

puritate calcar =68%

produs reactie =?

Answer 1

m.ip = 18,56 kg , p% = 68%

p% = m.px100/m.ip

=> m.p = m.ipx100/p% = 18,56x68/100 = 12,62 kg calcar

 12,62               m kg

CaCO3 --toC--> CaO + CO2

100                     56

=> m = 56x12,62/100 = 7,07 kg CaO
