Did you know?
WebWhen heat is absorbed from the reacting substances this is known as an Endothermic Reaction. Example 2C + H 2 - Heat → C 2 H 2 3O 2 - Heat → 2O 3 But remember, whether endothermic or exothermic, both types of reactions still … WebDec 11, 2016 · Clearly, the reaction is exothermic. Explanation: You are burning ethane; normally, the gas supplied to homes and labs is methane, CH 4. CH 4(g) + 2O2(g) → CO2(g) +2H 2O(g) The stability of the C = O and O− H bonds means that energy is released upon their formation, and the reaction is exothermic.
Endothermic gas is a gas that inhibits or reverses oxidation on the surfaces it is in contact with. This gas is the product of incomplete combustion in a controlled environment. An example mixture is hydrogen gas (H2), nitrogen gas (N2), and carbon monoxide (CO). The hydrogen and carbon monoxide are reducing agents, so they work together to shield surfaces from oxidation.
