How much energy is required to decompose 612 g of PCl3, according to the reaction below? The molar mass of PCl3 is 137.32 g/mol and may be useful.4 PCl3(g) → P4(s) + 6 Cl2(g) ΔH°rxn = +1207 kJ

+1345.8kj

Explanation:

No of miles of PCl3 = 612/137.32

= 4.46 moles

Therefore, 4 moles > 1207

4.46 moles> x

X= (1207× 4.46)÷ 4

X= 1345.8kj

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?
