There was a formatting issue with the specific chemistry symbols, there all correct in the picture below

2C(s) + O2(g) → 2CO(g)

C(s) + O2(g) → CO2(g) ∆H0= -394 KJ/mol

CO(s) + 1/2 O2(g) → CO2(g) ∆H0= -283 KJ/mol

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
