AJUTOR!! Inventati o problema si rezolvati-o ( de
acest gen : 500 g calcar de puritate 80% se descompun termic . Ce
cantitate de var nestins se obtine ? )

Answer 1

Ce cantitate de gaz se obtine prin arderea a 150 g de carbune de P=80%?
[tex] \frac{12g}{\frac{C}{120g} } + O2= \frac{44g}{\frac{CO2}{x} } [/tex]
$\frac{12}{20}= \frac{44}{x} => x= \frac{120x44}{12}=440gCO2$
P=80%
mt=150g
$\frac{P}{100} = \frac{mp}{mt} => mp= \frac{Pxmt}{100} =120g Carbune  pur$
Sper ca te-am ajutat.
