Wapno palone to tlenek wapnia CaO.
m Ca = 40u
m O = 16u
m Ca : m O
40 : 16 / skracam przez 8
5 : 2
Zad.2
Wapno gaszone to wodorotlenek wapnia Ca(OH)2
m Ca = 40u
m O = 2 * 16u=32u
m H = 2 * 1u = 2u
m Ca(OH)2 = 40u + 32u + 2u = 74u
%Ca = 40u/74u * 100% = 54%
%O = 32u/74u * 100% = 43,2%
%H = 2u/74u * 100% = 2,8%
wapno palone to CaO
mCa 40u 5
------- = -------- = ------- 5 : 2
mO 16u 2
Zadanie 2
skład % wapna pgaszoengo Ca(OH)2
m Ca(OH)2 = 40u + 2 * 16u + 2 * 1u = 74u
74u ---------------100%
40u -------------- x
x = 40u * 100% / 74% = 54% zawartość % wapnia
74u ---------------100%
32u -------------- x
x = 32u * 100% / 74% = 43,2% zawartość % tlenu
100% - 54% - 43,2% = 2,8% zawartość % wodoru
