Another common combustion reaction takes place inside the cells of your body. What is the word equation for burning magnesium? It usually occurs when a hydrocarbon reacts with oxygen to produce carbon dioxide and water. CaO (s) + CO2 (g) → CaCO3 (s) 3. Examples: Fe, Au, Co, Br, C, O, N, F. Ionic charges are not yet supported and will be ignored. Example: 2Mg + O2 -> 2MgO Magnesium and oxygen combine to form the compound magnesium oxide. It is hygroscopic, so it will form a solution with moisture in the air if not protected from ambient moisture. What's unusual, however, is that magnesium is reactive enough to be combusted and oxidized in a reaction with carbon dioxide: 2 Mg + CO2 -> 2 MgO + C. Under normal combustion/oxidation circumstances, oxygen is the reactant. Alkaline earth metals also react with oxygen, though not as rapidly as Group 1 metals; these reactions also require heating. 2 Mg (s) + O_"2" (g) -> 2 MgO First, we need to identify the type of bond and reaction.

The reason why it gets hot is that there is a COMBUSTION reaction such the Mg metal plus oxygen makes MgO called magnesium oxide. There is no water or anything close to H2O in the incorrect answer neither is there anything resembling the compound for heat which are present in a combustion. The combustion of hydrocarbons (substances containing only hydrogen and carbon) can be described as complete or incomplete, depending on the supply of oxygen and the products formed. A short explanation of how the reaction works follows the video. What does CR mean in a chemical equation. ; Complete Combustion. What are the types of chemical reactions?
