Without an external doing work, heat will always flow from a hotter to cooler object. Two objects of different tempatures always interact. There are three different ways for heat to flow from one object to another. They are conduction, convention, and radiation.
Answer:
Silica gel chromatography is a s good method for separating these methyl orange and biphenyl because of the wide difference in their polarity. Biphenyl will give a higher Rf value because it is a non-polar and moves faster on silica gel.
Explanation:
Silica gel is very polar, so polar components (like methyl orange) interact with and move slowly it but non polar components (like biphenyl) move faster on silica gel. Looking at their chemical structures, methyl orange has a polar end while biphenyl is a non-polar hydrocarbon. During silica gel chromatography, the methyl orange will interact with silica gel and move slowly but the biphenyl will move fast on the gel because it does not interact with silica gel. This will result to a very distinct separation of the components.
The biphenyl will therefore have a higher Rf value on TLC because it will move faster and longer on the TLC plate.
Answer:
The balanced chemical equation for the reaction between sodium and water is:2 Na ( s ) + 2 H2O ( l ) 2 NaOH ( aq ) + H2 ( g ) We can interpret this to mean: 2 moles of water and ? ... mole(s) of hydrogen.
