CAPF 2021Q12
Q: Which one of the following is an example of endothermic reaction? (a) CaO(s) + H2O(l) → Ca(OH)2(aq) (b) CaCO3(s) → CaO(s) + CO2(g) (c) C(s) + O2(g) → CO2(g) (d) CH4(g) + 2O2(g) → CO2(g) + 2H2O(l)
(a)CaO(s) + H2O(l) → Ca(OH)2(aq)
(b)CaCO3(s) → CaO(s) + CO2(g)
(c)C(s) + O2(g) → CO2(g)
(d)CH4(g) + 2O2(g) → CO2(g) + 2H2O(l)
