🦐 Co Oh 2 O2 Myślę, że się mylisz. Potrafię obronić swoje stanowisko. Napisz do mnie na PW, pogadamy.

Ca(s) + 2C(graphite) → CaC 2 (s) ∆H = −62.8 kJ. Ca(s) + 1/2 O 2 (g) → CaO(s) ∆H = −635.5 kJ. CaO(s) + H 2 O(l) → Ca(OH) 2 (aq) ∆H = −635.1 kJ. C 2 H 2 (g) + 5/2 O 2 (g) → 2CO 2 (g) + H 2 O(l) ∆H = −1300. kJ. C(graphite) + O 2 (g) → CO 2 (g) ∆H = −393.5 kJ. Calculate ΔH for the following reaction: CaC 2 (s) + 2H 2 The band at 370 nm can be assigned to the presence of Co(OH) 2 while the shoulder at 400 nm in ZX-6060-Co and ZX-n-Co samples can be assigned to the mixed cobalt oxide, Co 3 O 4 [51]. The Herein, we report a simple electrodeposition method for preparing Co 3 O 4 and Co(OH) 2 ultrathin nanosheet arrays (UNA) without using templates or surfactants. The obtained arrays exhibit high activity for oxygen and hydrogen evolution reactions, in both alkaline and neutral media. .
