Witryna31 gru 2015 · Combustion reactions are routinely exothermic. Why? To break bonds, you must expend energy. When bonds are made, energy is released. Let's take the … WitrynaCombustion, or burning, is a high-temperature exothermic redox chemical reaction between a fuel (the reductant) and an oxidant, usually atmospheric oxygen, that …
Methane is used in industrial chemical processes and may be transported as a refrigerated liquid (liquefied natural gas, or LNG). While leaks from a refrigerated liquid container are initially heavier than air due to the increased density of the cold gas, the gas at ambient temperature is lighter than air. Gas pipelines distribute large amounts of natural gas, of which methane is the principal component. Witryna21 gru 2014 · On the other hand, in the case of ethane, the heats of formation are -84.7, 0 and (2x) -37.4 kJ/mol; this reaction is endothermic by 10.3 kJ/mol.

Witryna12 gru 2024 · So are reaction for N O formation is. N 2 + O 2 → 2 N O. and the bond enthapy of N ≡ N is 891 kJ/mol, O = O is 495kJ/mol, and N O is around 90.2 kJ/mol. Therefore. ∑ b r o k e n = 1386 k J / m o l. ∑ f o r m e d = 180.4 k J / m o l. so. Δ H = 1389 − 180.4 = 1205.6 k J. This means that Δ f H [ N O] = 602.8 k J m o l − 1 this … Witryna11 sty 2015 · I thought all combustion reactions would be endothermic because you're always combusting something in the presence of heat.
