type="application/x-shockwave-flash" wmode="transparent" width="425" height="350"&gt;&lt;/embed&gt;&lt;/object&gt;&lt;br /&gt;&lt;br /&gt;A combustión é unha reacción química na que un elemento combustible combínase con outro comburente (xeralmente osíxeno en forma de O2 gaseoso), desprendendo calor e producindo un óxido. Os tipos máis frecuentes de combustible son os materiais orgánicos que conteñen carbono e hidróxeno. O produto desas reaccións pode incluír monóxido de carbono (CO), dióxido de carbono (CO2), auga (H2O) e cinzas. O proceso de destruír materiais por combustión coñécese como incineración. Para iniciar a combustion do butano é necesario alcanzar unha temperatura minima, chamada ignición ou de inflamación.&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1'
