Tepkimeler | Tepkime ısısı

--- | ---

I. $C(k) + O_2(g) \rightarrow CO_2(g)$ | $\Delta H_1$

II. $CO(g) + \frac{1}{2} O_2(g) \rightarrow CO_2(g)$ | $\Delta H_2$

III. $H_2(g) + \frac{1}{2} O_2(g) \rightarrow H_2O(g)$ | $\Delta H_3$

IV. $C(k) + 2H_2(g) \rightarrow CH_4(g)$ | $\Delta H_4$

V. $H^+(aq) + OH^-(aq) \rightarrow H_2O(s)$ | $\Delta H_5$

Buna göre, tepkimelerden kaç tanesinde tepkime ısısı ($\Delta H$) değeri standart oluşum entalpisidir?

Soruda görsel içerik var: A table with two columns titled 'Tepkimeler' (Reactions) and 'Tepkime ısısı' (Reaction Heat). Under 'Tepkimeler', five chemical equations labeled I through V are listed. Under 'Tepkime ısısı', corresponding Delta H values (Delta H1 to Delta H5) are listed. Reaction I: C(k) + O2(g) -> CO2(g). Reaction II: CO(g) + 1/2 O2(g) -> CO2(g). Reaction III: H2(g) + 1/2 O2(g) -> H2O(g). Reaction IV: C(k) + 2H2(g) -> CH4(g). Reaction V: H+(aq) + OH-(aq) -> H2O(s). Below the table, there is a question sentence in Turkish.
