What is this equation balanced: Octane reacts with oxygen to form ...
2014年12月16日 · This is the combustion reaction for octane, C_8H_18., a volatile and very flammable alkane that is a component of gasoline. The balanced chemical reaction is 2C_8H_18 + 25O_2 -> 16CO_2 + 18H_2O Here's a nice diagram of this reaction I've found on a French forum The chemical reaction described is C_8H_18 + 12.5O_2 -> 8CO_2 + 9H_2O
How would you balance the equation for the combustion of …
2015年11月11日 · The complete combustion of any hydrocarbon gives carbon dioxide and water. I will represent the combustion of hexane. C_6H_14(g) + 19/2O_2(g) rarr 6CO_2(g) + 7H_2O(g) Is this equation balanced? How do you know? How is the complete combustion of octane, C_8H_18, to be represented? I balanced the carbons, and then the hydrogens, and then the …
2 C8H18 (l) + 25 O2 (g) -> 16 CO2 (g) - Socratic
2015年2月1日 · Step1. You must first determine the number of moles that are in 4000 g of octane, using the molar mass of octane. Step 2. Then you must determine the number of moles of carbon dioxide that can be produced by that number of moles of octane, based on the mole ratio between octane and carbon dioxide in the balanced equation. Step 3.
What are the products of complete combustion of octane?
2017年11月22日 · Octane is made up of simply Carbon & Hydrogen. In complete combustion, all the carbon and hydrogen atoms present react with oxygen ('combust') and thus the following occurs; #C# + #O_2# = #CO_2#
How would you write a balanced equation for the combustion of …
2015年11月10日 · 2C_8H_18 + 25O_2 -> 16CO_2 + 18H_2O You just have to check the number of atoms of each element is the same in both sides. You can do it by steps starting with the unbalanced equation C_8H_18 + O_2 -> CO_2 + H_2O By making a list of the elements and the number of atoms on each side of the equation 8-C-1 18-H-2 2-O-3 Then as you can see, the …
Balancing Chemical Equations - Chemistry - Socratic
Mass is conserved rather than created or destroyed so when a chemical equation is written, it must be balanced so that there is the same amount of reactants going in as yielded product. The equation is balanced by changing the scalar numbers that precede each part of the equation.
How do you write chemical equations for combustion reactions?
2016年3月23日 · The combustion of octane C_8H_18 follows this reaction 2C_8H_18 + 25O_2 -> 16CO_2 + 18H_2O A combustion reaction takes a hydrocarbon and burns it in oxygen to release carbon dioxide and water. A hydrocarbon is a molecule that contains carbon and hydrogen. The basic equation looks like this. The combustion of propane C_3H_8 follows this reaction …
How many moles of oxygen react with 6 moles of octane?
2018年3月16日 · You can double the entire equation if you like..to remove the half-integral coefficient. I think the arithmetic is easier this way... AND the question proposes the complete combustion of #6*mol# octane. Given the stoichiometric equation, we require #6xx25/2*mol# dioxygen...i.e. #75*mol# #O_2#. And clearly we could further ask for the mass of ...
This reaction shows the complete combustion of octane, C8H18, a ...
2018年1月26日 · We use the equation... C_8H_18(l) + 25/2O_2(g) rarr8CO_2(g) + 9H_2O(l)+Delta I halved your equation in that I find it is easier to determine stoichiometric equivalence in this form rather than the given form. And so if we burn 2.1*mol of octane, we need 2.1xx25/2*mol=26.25*mol with respect to dioxygen...and certainly we could also calculate an …
How would you balance the combustion reaction between octane …
2015年11月3日 · C_8H_18 +25/2O_2 rarr 8CO_2 + 9H_2O Is the above equation balanced? Don't trust my arithmetic. What would be the physical states of each participant in the reaction? Internal combustion engines rarely combust gas this cleanly, and a lot of C particulate, and CO gas are given off. If (say) 1 equiv each of C and CO were given off by the combustion, how …
