Ibuprofen is used as an anti-inflammatory agent used to deal with pain and bring down fevers. If it has a molecular formula of C 13 H 18 O 2 , determine the balanced combustion reaction when it is subjected to high temperatures.

Here we're told that Ibuprofen is used as an anti inflammatory agent to deal with pain and bring down fevers. If it has a molecular formula of c 13h1802, determine the balanced combustion reaction when it is subjected to high temperatures. Alright. So in a combustion reaction, this compound would react with 2, and it would produce water plus c02 as byproducts or as final products. Here we need to balance this out, so we're gonna make a list. We have carbon, hydrogen, and oxygen on this side, carbon, hydrogen, and oxygen on this side. We have 13 carbons, 18 hydrogens, and then 2+2, 4 oxygens. Over here we have 1 carbon, 2 hydrogens, and 3 oxygens. Here the numbers don't match for carbon, so what do I do? I have to put a 13 here. That 13 gets distributed to the carbon and to the oxygen. So we have 13 times 2, which is 26, plus one more oxygen is 27. Hydrogens don't match. This side is 18, the other side is 2, so I'm gonna throw a 9 here. That 9 gets distributed to the hydrogens to give me 18, but it also gets distributed to the oxygen. So I'm going to have 9 oxygens here, plus the 26 over here with the c o two, for a total of 35. Alright. So we have to think about, okay. How do I get 35 on the reactant side? Well, first off, we already account for 2 here. Right? We already have 2 oxygens there. So that means I need 33 more oxygens to get to 35 total on the reactant side. Can't use 16 as a coefficient because 16 times 2 is 32. Can't use 17 because 17 times 2 is 34. So the number I put here is 16.5. 16.5 times 2 gives me 33. 33 plus these 2 here would give me 35. Now remember, we cannot use, decimals or fractions when it comes to coefficients. In these cases, we multiply the entire thing times 2. So we get new coefficients, so all the coefficients get multiplied by 2, so all of these will get multiplied by 2, since I'm multiplying the whole equation by 2. So that'll give me 2 c 13h1802 plus 3302 gives me 18 h20 plus 26 c02 as my products. So this would represent the combustion the balance combustion reaction of Ibuprofen.
