Calculate the volume of carbon IV oxide measure... - JAMB Chemistry 1991 Question
Calculate the volume of carbon (IV)oxide measured at s.t.p, produced when 1 kg of potassium hydrogen trioxocarbonate (IV) is totally decomposed by heat?
(G.M.V. at s.t.p 22.4 dm3, K = 39, O = 16, C = 12, H = 1)
(G.M.V. at s.t.p 22.4 dm3, K = 39, O = 16, C = 12, H = 1)
A
28 dm3
B
56 dm3
C
112 dm3
D
196 dm3
correct option: c
2KHCOdm3 → K2CO3 + H2O + CO2
2(39 + 1 + 12 + 48) 22.4 dm3
200 g 22.4 dm3 of CO2
1000 g (1000) / (200) x 22.4 = 112 dm3
2(39 + 1 + 12 + 48) 22.4 dm3
200 g 22.4 dm3 of CO2
1000 g (1000) / (200) x 22.4 = 112 dm3
