As already mentioned by me in the comments, both the approaches are exactly the same. To explain this point, I would like to find the numerical value of the question posted by you in the comments using both methods. By Manipulating the Equations: Given: $$ \begin{align} \begin{array}{ c c} \ce{S + 3/2O2 -> SO3 } & ΔH = \pu{-395 kJ} \\ \ce{2SO2 + ...

To add further to your question, for a silver diamine dental product (Riva Star by SDI), the white precipitate disappears after applying more potassium iodide to the mixture. The excess solution in the tooth cavity is then rinsed off with water. There is some cool chemistry going on here but I am unsure what it is. Riva Star comes in 2 solutions that are ...

Let's look at the system: clothes + grease + water + soap. To be more specific: a) We prefer to wear hydrophilic materials to manage moisture removal (sweat). The clothes could be cotton, wool or linen, which are naturally hydrophilic, or synthetic, like polyester or acrylic, which are naturally hydrophobic, but are treated with a finish to make them ...

It is well-known that “Solids do not react together at room temperature over normal time scales and it is necessary to heat them to much higher temperatures, often to 1000 to 1500 °C, in order for the reaction to occur at an appreciable rate.” Ref 1. One reason this is true is that even when molecules of one solid diffuse into another solid, the resultant is ...

I am thinking of three methods, you could put the coin in a scanning electron microscope if it has a X-ray spectrometer attached and then get a spectrum of the X-rays which come off the coin. If you had access to a TRIGA nuclear reactor then you could try neutron activation combined with gamma spectroscopy. If you use a short irradation time in the reactor ...

Your "logic and reasonning" is entirely speculative and based on no knowledge of chemistry. Oleic acid and Linseed oil will not mix with straight chain hydrocarbons. Surfactants used in shampoos are highly hydrophilic and would not work in this instance. If there was a surfactant it would have to be a lipophilic one like the Triton™ X-100 that were ...
