The equation for the combustion of CH4 (the main component of natural gas) is CH4(g)+2O2(g)→CO2(g)+2H2O(g) ΔH∘rxn=−802.3kJ
How much heat is produced by the complete combustion of 271 g of CH4? in kJ

Heat produced =  -13588.956 kJ

Given

The reaction of combustion of Methane

CH4(g)+2O2(g)→CO2(g)+2H2O(g) ΔH∘rxn=−802.3kJ

271 g of CH4

Required

Heat produced

Solution

mol of 271 g CH₄ (MW=16 g/mol0

mol = mass : MW

mol = 271 : 16

mol = 16.9375

So Heat produced :

= mol x ΔH°rxn

= 16.9375 mol x −802.3kJ/mol = -13588.956 kJ

five factors that determine the state and condition of the atmosphere and, therefore, influence and determine the weather. They include:

These factors can cause different properties in sections of the atmosphere or air masses. We often might think of the atmosphere as a large ball of air that encircles the Earth. While that is true, it is broken up into distinct sections with different physical properties. These properties are determined by the five factors just mentioned, and the differences in the properties between air masses are what cause the changes in our weather.
