[1 mark]..... 5 (c) Oxides of nitrogen are also produced during the combustion of paraffin in air. The simulations capture the important characteristics of the soot formation process. _____ _____ _____ _____ (2) (ii) Write an equation to show how nitrogen monoxide in the air is converted into nitrogen dioxide. 5 (c) (i)Explain how these oxides of nitrogen are formed.
Hydrocarbons can also burn with a restricted air supply, and in this case the products of combustion include CO, C, (as soot) and H2O For dodecane, the incomplete combustion equation could be similar to: 2C12H26 + 23O2 → 20CO + 4C + 26H2O Decane is C10H22 (CnH2n+2). The combustion reaction of dodecane is as follows: C 12 H 26 (l) + 18.5 O 2 (g) → 12 CO 2 (g) + 13 H 2 O(g) ΔH° = −7513 kJ. This is called complete combustion. 6 Answers.
since you have 10 carbons, you will form 10 CO2, requiring 10 O2. You will form water and carbon dioxide so . But the excess is not included in the equation.
Favorite Answer. One litre of fuel needs about 15 kg of air to burn, and generates 2.3 kg (or 1.2 m 3) of CO 2 upon complete combustion. To get the … Write an equation for the incomplete combustion of dodecane to produce gaseous products only. Lee. Since you have 22 hydrogens, you need 11 oxygens, or 5 1/2 O2. _____ (1) (c) Oxides of nitrogen are also produced during the combustion of paraffin in air. This happens with any hydrocarbon. We shall take methane as an example. Explain how these oxides of nitrogen are formed. C10H22 + O2 → H2O +_ CO2 . Write balanced equation for the complete combustion of decane.? [2 marks]
5 (b) The combustion of dodecane produces several products. Relevance. Question: Write and balance equation for the complete combustion of decane, {eq}\rm C_{10}H_{22} {/eq}. Incomplete combustion means burning in a lack of air (not enough oxygen). The combustion of dodecane produces several products. /3Zzo .. (1) Oxides of nitrogen are also produced during the combustion of paraffin in air. Jet fuel surrogate. (i) Explain how these oxides of nitrogen are formed. A reduced n-dodecane-PAH mechanism is proposed for combustion and soot predictions.. A multi-step soot model was coupled with the mechanism to predict the soot formations. If there is not enough oxygen available for all the carbon to turn into carbon dioxide (see complete combustion), then some or all of the carbon turns to carbon monoxide. Answer Save.
Write an equation for the incomplete combustion of dodecane to produce gaseous products only. • Effects of ambient conditions (temperature, O 2, density) on soot were discussed.. 1 decade ago. Write an equation for the incomplete combustion of dodecane to produce gaseous products only.
