When the sun becomes active, the occurrences of phenomena such as solar flares, coronal mass ejection become frequent. The amount of high-energy particles and extreme shortwave radiation released, such as X-rays and UV, will also increase. These phenomena affect the ionosphere of the Earth's atmosphere the most.
Answer:- -2260 kj.
Solution:- It could easily be solved using dimensional analysis. From given information, the enthalpy change for the combustion of 2.00 grams of propane is -102.5 kj. It asks to calculate the enthalpy change in same conditions for the combustion of 1 mole of propane.
We convert 1 mole of propane to grams using molar mass(44.1 gram per mol) and then calculate the heat using the given information as:
= -2260 kj
Hence, the enthalpy change for the combustion of 1 mol of propane is -2260 kj.
